Tamiya TRF503 announced with picture

[qatmix]

http://www.thercracer.com/2014/01/42275-trf503-chassis-kit-announced.html

Looks like a nice evolution of the 511 :)

Also the new 2WD should be announced as well

[kaylon]

I'm getting addicted to Tamiya again :)

K

[jph]

Thanks for the heads-up Qatmix, I wonder how long it will be before these new kits are available to buy?

Really looking forward to seeing the new 2wd :-)

[Fredrik Emilsson]

501X arms front, WO driveshafts and BB etc. Looking good!

[DaveG28]

Oh Tamiya Tamiya, why do you do this to me, releasing such a sexy piece of kit after I've finally gone elsewhere!

Only Tamiya would announce all new off-road race cars just AFTER ditching their off-road team :o

[qatmix]

I know, however it looks great (added a few more details)

I think I know what I want for my birthday this year :) .. or maybe the tractor ;)

[DaveG28]

It does look great, I am very conflicted haha! I guess we are looking at a spring release date which is just as we stop all 10th scale for the summer round here :(

[guinness]

would be nice a new tfr201

[Origineelreclamebord]

I'm quite surprised to see this release - like many of us probably. I must say it's spec is not highly surprising, but that is a good thing, they're building on a highly rated belt-drive platform - as far as I know anyway! :) Also, they seem to go from one extreme to another: Until now we're modding and hopping up Tamiya's, and this car has got an impressive spec and even a brass weight kit included!? :o

Based on the spec sheet I don't see a big item they should have done differently on the car...and to be honest with Tamiya's recent non-TRF releases and weird decisions on the TRF-front it's become a bit unpredictable what they'll have in store! :lol:

By the way, some more pictures:

Funny to see in the text in the first picture (on the left) they say 355mm wheelbase... I suppose that should be it's total length? :lol:

[Dyna]

Interesting to see thay have gone for an aluminium lower chassis plus metal centre pulleys as well.... Seems just about everyone is going for metal lower chassis these days - bandwagon anyone ?

I cant see that the 'new' 2wd will be radically different either, maybe just using up all the stock of the 201 parts with the XR & XM conversion kits into a all-in-one box ?

[Origineelreclamebord]

Seems just about everyone is going for metal lower chassis these days - bandwagon anyone ?

It's not surprising. With power and battery life no concerns anymore for 5 minute heats, cars don't have to be as light as possible. In fact a heavy car is a lot more stable over bumps and jumps, so weight can be a very good thing.

Aluminium chassis plates are an easy and cheap way to achieve that extra weight low down on the sprung mass of the car. Besides, aluminium chassis plates (when not elaborately machined with slots and stuff) should prove to be cheaper than carbon plates. A small benefit might also be that an aluminium plate can better dissipate heat than a carbon one. And last but not least, I think you'll find the 'usual' chassis plate alloys (6061-T6 and 7075-T6) to be stiffer and more durable than most carbon fibre in the RC industry (which often contains relatively few layers of carbon for it's thickness, reducing stiffness and strength).

[Jamesk]

Well i will buy one and retire the 502.2 i have. I like the idea of a metal lower plate,if its simular to to XM on the 201 it will bring better handling.

Even thou i doubt it will be any cheaper just because of the chassis materials have changed.

jK

[Dyna]

Oh i agree that a car doesnt have to be as light as possible these days, but the extra weight of a milled ally chassis ( which this new 503 is ) verses a carbon one will be very minimal.

Cost of a milled & anodized ally chassis over a straight carbon one ? Again minimal - in fact the carbon ones would probably be cheaper.

Heat dissipation, well possibly it might help a tad, but i cant remember ever having problems with over hot motors anyway in a carbon chassis - in my 501x & DB01r they run quite cool - just have good ventilation and a motor heatsink :)

Stiffness.... hmmmm again maybe, but a) does the TRF 4wd platform NEED to be any stiffer ? The 501x and 511 are already very stiff... And b) not so sure about being more durable in the real world. Ok the ally chassis might not break or shatter like a carbon one would do so you might be able to finish the race you are in, but if you have hit something that hard it will definitly be bent or at the very least tweaked. And thats my main bug-bear with ally chassis in general. Once they are tweaked its impossible to get the car set up again properly. It might not be broken in half like a carbon one, but its then got to be replaced anyway.

Better handling being ally instead of carbon ? Maybe, but you would have to do back-to-back tests to confirm or deny that one and on different tracks. Marc Rheinard might be able to tell them apart, but im a very average driver so i very much doubt i would notice the difference on a double-decked 4wd chassis tbh !

Anyways enough of that as it doesnt really matter - it looks to be a very nice car & its a TRF so im sure we will all buy it no matter what its made of :D

I just hope its not too expensive and spares back up is decent...

[SiR_Dave]

About Damn Time Tamiya :drool::drool:

[Fredrik Emilsson]

Looks like db01 front arms (soft trf501x ones), dn01 rear arms. XV01 rear hubs. New WO driveshafts. No more lost pins...

[Kimo]

Looks pretty awesome to be honest... :o

[discothesnake]

Very nice although a bit surprised to see them continue to use 10mm hexes on front and pins on rear. Everyone else seems to be going 12mm hex all round.

Typical Tamiya tho, looks stunning.

[Aussie Top Force]

Very nice! Why not include a new body, which would be the cheapest part!. Not sure that it'll tempt out of the 502X though. Open belts on dusty tracks?? The new Losi 22-4 has an enclosed system for similar spec. So the 503 will need to be keenly priced and well supported.

Mmmmm....the 201XM and Egress 2013 have left some big dents in the racing budget of late!

Additional: a close look at the Parts tree shows (bottom third of image) nice blue 12mm hex's near the new universal joints:

Id you look a some of pictures that has the prototype chassis.. you will see 12mm clamping hexes for the rear ...:D... also there is a way to run 12mm ones on the front as well... and only have a 1.5mm wider front track :p

[SiR_Dave]

Anymore news... pic's ect ect... possible release date:bored::eh?::drool:

[MHeadling]

From what I'v read about it, March release date, price will be around $550-600

Lots of pics on tamiyablog, area52.cc and various other sites

[Jamesk]

£ 360 sounds about right for a TRF kit. Expensive but think I'll have one.

Jk

[Aussie Top Force]

What are the 511 gear diffs like for those that have used them? Are they low maintenance and what improvement to handling do they offer over ball diffs?

[SiR_Dave]

From what I'v read about it, March release date, price will be around $550-600


Really:wub:wub

[MHeadling]

511 gear diffs are pretty good, the stock plastic bevel gears are prone to stripping if not shimmed up but the TA06 steel bevel gears fit in the 511 diffs then they are pretty bomb proof

They are cheap too, new on eBay from HK about £12

[fastinfastout]

my gear diffs have leaked quite a bit though......

[MHeadling]

Forgot to mention tamiya have done a Red TRF o ring kit for the gear diffs, this sorts it

[MHeadling]

Here are the parts I used:

Nice video here

[kentech]

Tamiya posted the TRF503 product page together with a Japan release date of March 22.

http://www.tamiya.com/japan/products/42275/index.htm

If you want the translated version of that together with more info also translated from Japanese see here:

[shedloads]

Car looks good! Anyone know what shell would be used?

[xfactor]

Whatever the body used you wont want to use it. It states,

Body Price 79,000 yen :woot: wonder what its made of. You wont want to mess that body shell up with bleeds :D

[SiR_Dave]

Nice... that means we should be able to get this kit form RC Champ for about 10~15% off of Tamiya's Retail price :drool:

[Roel]

Whatever the body used you wont want to use it. It states,
Body Price 79,000 yen :woot: wonder what its made of. You wont want to mess that body shell up with bleeds :D

Think that's something like the price without a body, around €580 or 480 Pounds.
There is another price of 83790 Yen, €612 or 510 Pounds which might be with body?

[Aussie Top Force]

The Proline forward cab for the 502 might be a fit, as well as the original 511 body. Not sure if there is a proline phantom body available yet? Rhiehard was using it at the Reedy RoC:

Look at the car not the girl!:lol:

[qatmix]

expect 30% off the RRP in Japan

[kentech]

Regarding the price. The 503 is slightly more expensive compared to the TRF418, so you will get a pretty good idea of what the 503 price will be by checking the 418 price on various markets and adding a bit.

[SiR_Dave]

55,300円 Will be the street price after tax from RC Champ and Super RC in Japan... they can be pre-ordered now:D

[kustom chris]

TRF503 $839.99 AT TOWER HOBBIES
far out thats expensive

[Roel]

55,300円 Will be the street price after tax from RC Champ and Super RC in Japan... they can be pre-ordered now:D

About €400 or 335 Pounds, sounds good.

Did he gave a date when it's available?

[DaveG28]

Must...resist...

[GRIFF55]

Do it wookie!

[qatmix]

Want one!! It might even make me want to race buggies properly again..

:woot::thumbsup: Do it Dave... I can send some of your TRF502x parts back to you if you need them LoL:p

[MHeadling]

Any other on line stores doing a pre order??

Had a look at rc champ (crap website) and couldn't find super rc ??

Any links would be handy

[SiR_Dave]

I can post up SuperRC link after I find it... :blush:

Here is the Super RC site link for the 503... it would be bets to e-mail them...:yawn:

[MHeadling]

Cheers Dave :thumbsup:

£327 very tempting!

[SiR_Dave]

No problem:D

I'm looking to be picking one of these up from Champ on the Friday the 21st or Saturday the 22nd:drool:


I hope they will have some spare parts available at the release date at some of the shops in Tokyo... other wise my little Japan trip might be :bored::eh?:


On a side note it looks like Denmark will be getting the kits in at the end of this month..??!!:o:o:eh?::confused:

[DaveG28]

If resistance fails I will be emailing Stella Models, they usually have good pricing!

[SiR_Dave]

I'm willing to bet you will get one :p

[GRIFF55]

Ditto!

[MHeadling]

Chaps what about doing a group buy? Maybe Stella or rcmart would do a deal for a box full of 503 to the UK??

I know of 4 people at my local clubs who want one

[rcaddict]

TRF503 wont be available in the U.S. until April,
but I found a tasty close-up video to watch in the meantime. :D

Why wait.. you can order it overseas and still get it quicker and cheaper than what most shops will be selling them for in the U.S.:eh?:

Just think the yen to dollar has the best it has been in a few years so it's around 102~105 Yen to the Dollar. so you might be getting the kit for around 500$~515$ shipping should not break the bank and would only take 10~14 days tops or you can pay for EMS if you want it quicker :D

[D-StyleNZL]

Wonder if they will have a Ti screw set available at time of release, or if the 511 set will work....

[SiR_Dave]

I would think that 95% of the screws from a TRF511 are the same .. ;)

[rcaddict]

I would be willing to bet that HediSan over at CHAMP is already turning Ti screw sets for 503 right now as we speak... ;)

[D-StyleNZL]

Got an email back from Stella and Joyhobby saying that they are doing pre-orders. Just waiting to get word back on price.

[SiR_Dave]

I would be willing to bet that HediSan over at CHAMP is already turning Ti screw sets for 503 right now as we speak... ;)

I'll be at the Akihabara Champ Store picking up my TRF503 on Friday the 21st of March:D:woot::woot::thumbsup:

[rcaddict]

Lucky Bastard! I have to wait for my friend who fly's to Japan every other month. I think he might be leaving for Tokyo next week. I should have him stop by at CHAMP for me. :drool:

Otherwise I have to wait for April. :yawn:

[SiR_Dave]

Less than one month now:drool::woot::woot:... Can't wait!!

The new TRF503 have just arrived today in Denmark, ready to ship to shops in Denmark and Sweden.

http://www.tamiyaracing.dk/?p=1341

:-)

[Roel]

Any shops out there that have the 503 on the website?

Would be intersting to see what the european price is going to be.

Seidel in Germany has the car on the site but no price yet.

[Welshy40]

Problem with Tamiya is they dont use good materials and then slop is stupid after a short period of time plus the cost is stupidly expensive and spares are hard to come by and have to be bought from abroad. Not worth it.

[Roel]

Ow hello, mister Tamiya hater.

I'm sure someone, somewhere will value you opinion but I doubt anyone here will give a %$#@ about it.

I believe someone´s been the happy owner of a Striker in the past :lol: If your view was less rant and more constructive I would've agreed on it that the TRF201 is somewhat brittle in places (the front end mainly), but I gained that experience in my rookie year, which explains more than half of the breakages... :p

Anyway, cool to hear the 503 is already arrived in Europe. I can't wait to see it in the flesh!

[rcaddict]

Is the production version of the 503 coming with an aluminum chassis, or will it be carbon graphite? :confused:

[Fredrik Emilsson]

Aluminium chassis. :-) undertray and wing included, but no body.

[patez]

BTW, which body will fit? I saw phantom was released for b44.2. I wonder if it works for 503 too. It would look good side by side with my 201xr phantom.

[SiR_Dave]

The Pro-Line Phantom will work on all the TRF 4wd buggy series if you look closely at the front of the Phantom body that was used by Marc R at the most recent Reedy Race you will see it has cut lines for the B44.2;)

[patez]

Thanks! Proline bulldog was so dull lookin.

[SiR_Dave]

I think that there are a few other options out there for body's for the TRF 503 once it comes out... pretty much anything that will fit the B44.2 should fit the TRF503 as well.. . as well as a few makers in Japan that have bodies for the 511 that are not cab forward:)

[Aussie Top Force]

Looking good. However, the 502X is serving my well and has plenty of life left in it, so unfortunately I don't think the 503 will find its way into my collection any time soon.

[Fredrik Emilsson]

It´s a really nice kit.
Good that they included metal gears in diffs and also hex adapters. Also like the turnbuckles.
Shame that they did´nt include hard hex ball connectors...

I think I might purchase this machine in the very near future. I bought my 501X upon release (still a nice buggy), seems the 503 is worth the money.

Where can I found the manual????
I want to check parts if can use them in my 511x

[SiR_Dave]

Where can I found the manual????
I want to check parts if can use them in my 511x

I only have these pictures of the Manual so far.... but most of the parts I have crossed referenced are all new... 8series part #... so there are all special order from Tamiya currently:cry:

[Fredrik Emilsson]

You can use some parts on 511 like suspension arms, camber mounts, damper towers, all plastic parts etc.
Some parts would fit with minor mods, like making new holes etc.

Let say you want to update your 511 to 503 specs. In short, you want the longer chassis with new motor position and new 12 degree kickup.

You would have to buy (probably not 100% complete list):
alu chassis plate, rear (front) suspension mounts, center bulkhead (right), motor mount, new topdecks, new front bulkheads (upper and lower) with bulkhead spacers, new drivebelts, new front suspension mount.

Center bulkhead mount is shorter. So the 511 bulkhead does´nt fit the 503 chassis unless you make new holes in chassis. Could be done of course.

Front upper bulkhead is modified to fit new kickup and is now 12 degrees, 511 had 8 degrees. Not a new 502X mistake...;)
You can use 503 upper bulkhead on 511 and vice versa. Basic dimensions are same, but angle on damper tower would be wrong of course.

503 damper towers fit 511 and vice versa. Rear tower is basically same, with outer holes removed and inner added. Wing mounts are lowered ~10 mm and moved out ~3.5 mm.

Front tower sit ~1.5mm higher. Outer holes removed.

Front suspension mount to change kickup. Also front lower bulkheads are modified for new kickup of course. (Want the suspension mount to be in the correct angle)

You can then add gear diffs, BB dampers etc to the list and you will realise that buying a 503 is a better option.

[Origineelreclamebord]

At least Tamiya produced the car so there's no doubt about it whether it's more financially interesting to replace or upgrade your car :lol: Then the nice part of the story is that many suspension spares are still compatible - perhaps not the same, but at least they're compatible!

By the way, thanks Dave for sharing the build pictures - the car looks amazing! :)

When to look around to buy a few TRF511 hop-ups (alloy steering, ti screws/shafts etc) Not much around that are a fair price.
Wonder if you can order the rear Hex's just by themselves.

[SiR_Dave]

I have inquired about getting the "normal" spare parts for the TRF503... and Tamiya Japan said that they will not have spare parts until after the 22nd of March release date in Japan.... so... .I would think the 1st week of April:cry::yawn:

Unless some gives me $600 as a gift, there's no way my wife would let me buy another RC Car at the moment! Still, it can't stop me wanting one!

My 502 went well on the weekend, it was quick and capable, sadly my lack of track time ended in a poor result for the 502X.

In fact I'm saving dollars for RC-10 Worlds Car with a justification 'its for my birthday in April'. A $600 503 on top of that would put me in the dog box for some time:thumbdown:

Funny thing with the rear Hex's, I wont be using them for a while untill all my wheels from my 502 (still running Pins) are past there use by date.

[patez]

I just started to build mine :p

:drool::drool: Very nice:woot::woot:

Looks like the new shock towers are 3.5mm:eh?::eh?: they look "BEEFY":wub


Post up more pic's when you can please:D

Looks great! Would like look grey next to my 201 XR! Aluminium Chassis and blue bling, very nice!

[SiR_Dave]

5 more days and I will have this kit in hand :woot::woot:..

Can't wait:drool:

[Roel]

A $600 503 on top of that would put me in the dog box for some time:thumbdown:

Will be worth it. :p

[patez]

And its ready to go!!

The manual setup was a bit different what i expected. Sway bar is there, and 4mm of limiters in the rear shocks.. Also the rear shocks are in relatively "stand up position"

Some info for those thinking of buying a 503, RCMart in Hong Kong currently have the kit listed for $410, and airmail delivery to the UK is $45, so a total of $455 (~£280). Thats the cheapest I have seen it anywhere, so I just ordered one plus a few extras! :)

Nice picture of it build up patez... what body do you have planed for it?:blush::woot:

I'm going to try out the following bodies to see if they even fit :thumbsup:

TRF501x Worlds body
TRF511 body
Proline Bulldog body for the TRF502x

leave some for us :thumbsup:

[SiR_Dave]

There site says 4... but they have only 2 now:p 2 buddy's just purchased some:yawn:

[patez]

I have old 511 body which fits it perfectly. I'm gonna try b44.2 phantom for it. The included sidepods are cut out from 511 undertray and they're attached on the topside. The old undertray holes align with new lower deck. Many bodies should fit dependending of the size of electronics.

Crazy nice!
Did you put some extra weight under the lipo?? Is it out of box or just your own?

[patez]

The weights are included in the kit. Everything is "stock" as instructed in the manual. As an alternative, I suppose you could put some weight in the middle where you see 2 empty holes between the batteries.

[Toon]

They were showing 4 in stock when I placed my order, which had gone down to 0 earlier today, but they are now showing 4 in stock again, but at the slightly higher price of $429.90 (still a great price though, the kit is $480 + shipping at Stellamodels).

is that a normal pin axle setup on the rear, and hex b44 size on the front, as per previous trf 4wd's?

[fastinfastout]

I dont recall the trf511 to being this cheap. This car is a bargain!

[patez]

For the rear theres pin and 12mm hex parts included in the kit. front is smaller old style hex. I changed it to 12mm too.

Nice I have one of the Proline phantom B44.2 bodies that I have fit tested one on my 501x/502x/511 and it's a little tight in the rear around the shocks and the chassis on the 501 & 511.. but on the 502x it fits rather well... which makes me think with the thinner chaissis of the 503 it should work fine... or be really close with the way the servo mounts on the 503.... I'll be able to double check next week for sure:eh?:

Now with the 511 body that you have fitted to the 503... how much room does the body have around the bump for the motor now that motor has been moved forward 7mm on the 503.. Just wondeing since I would really like to use my 501x bodies:)

Because the chassis is longer, i can actually move the body forward or backward ~7mm maybe. But still, there's a little room above the motor even if the bump is not at the exact spot. I had trouble fitting my wiring on 501 earlier. Now that there's more room in the back of the spur, its quite handy to put the motor wires under the antenna holder.

The motor is also moved inward. So there's more room about 8mm in that direction. The sensor wire doesn't rub against the body anymore.


If the servo arm rubs against the body, i can reverse the servo with a shorter arm. (in the manual a short servo was fitted other way around and standard was fitted like i did)

Btw, did you try b44 phantom with 511 undertray?

Thanks.... I kind of figured the 511 body would work...:drool: and now that the chassis is longer it should not be that much of a difference at all now that there is a spacer for the rear body mount:D... now as far as the servo rubbing... I was talking about the outside mount vice the servo horn arm:lol:.. The TRF 501x worlds body has the nice bumps in there for that which is nice and the 511 body is not a issue..

Now as far as the 511 under tray.. it works... I'll post up some pic's later today:D

Also if you get a chance to weight it.... might be nice to see if the car needs to go on a diet:lol:

The alu plate is quite narrow, so that doesn't even add that much weight if you ask me. +/- 50g? The gear diffs may well prove lighter than the ball diffs (by about 5-10g a piece?) and the big bores will be heavier (about 20-30g in total?).

[Aussie Top Force]

Nice paint work! Who's talent is responsible?

[Aussie Top Force]

Also if you get a chance to weight it.... might be nice to see if the car needs to go on a diet:lol:

I think the idea of the aluminium bottom plate is to add weight low in the chassis, other wise carbon fibre is the better choice. Heavier cars are more stable and generate more traction, especially for high powered modified motors and the fact that battery technology is getting lighter.

Stock racing on the other hand, i.e. 17.5t as we do in Aus, being light can help acceleration with tall gearing. The 503 and the 201 are clearly designed for high powered motors considering the drive ratios that come standard.

Some one buy my FF01's so I can afford one of these beauties!:cry:

I have the weight of the 39T ball diff... I would think the Gear diff will only be +~- a few grams.. so thats fine...:) and the Chassis has all of those nice cut outs in it.. And for the Shocks the Big bores 20grams more so you nailed that;)

We all know it will happen:blush::bored:

[patez]

My car weights 1732g with 511 body in driving condition and with the extra 50g weights. Batteries we're 260g.. other electronics i dont know (hobbywing 120A xerun and savox 1257 servo ko propo tiny receiver).. So under 1700 without the extra weight.. Gear diffs must weight more than ball diff, they're filled with fluid after all.. But around 1700g is quite typical these days or actually on the lighter side? Also i have a feeling, i'm gonna need those extra weights for low-medium traction.

The lower deck feels very light. Its only 2mm thick compared to 201xr which is 3mm.

[SiR_Dave]

1723g:cry::bored: time for a little diet:lol:

[ridgeracer]

My DB01RR is lighter than that !

[patez]

well its 1682 without the extra battery weights. I suppose you dont use them on hi traction. Unfortunately theres no indoor track where i live.

[Toon]

So in standard spec, 503 rear wheels are either pin or 12mm hex fitment, and front wheels are 10mm hex? Is 10mm hex the standard fitment for 4WD front wheels, and if not, do any manufacturers other than Tamiya make wheels that will fit? I think I read that front wheels for the b44.2 are the same?

Sorry for all the questions, but I am coming from a 201 buggy, so really have no clue as to what the 4WD buggies generally use, and don't want to buy wheels that won't fit. :confused:


In other related news, I saw that the price of the 503 at RCMart has shot up to $480 now! I am so glad I ordered mine a few days ago! :)

[SiR_Dave]

10mm B44.2 front wheels fit the TRF 4wd buggies... but you need to make sure that you have the wider of the two that they sell... the 503 comes with the correct ones.. the earlier 501x ones were a little thin and caused rubbing against the steering upright when using other than Tamiya Wheels;)

The Body of the 501x is a bit longer compared to the 511 in the nose area.... so you have room to shift the body a little bit.... I'm sure it will be close around the motor.. but since it works on the 511 without any issues.. I don't think a 7mm forward motor should cause a issue:blush:

Is there any reason why the 503 wouldn't work well as a 2WD buggy? And has anyone tried running a 501/502/511 in 2WD?

The only reason I ask is that I have had a bit of 'buyer remorse' since ordering my 503 (which left Hong Kong today). All of my friends that I will be racing offroad with this year will be doing the 2WD class. I already have a TRF201 with a Vega chassis, and I do plan to buy the new version of the 201 when it is available, but that may be a few months away yet, and the 503 looks so good with the gear diffs and big bores. So I am thinking about trying it in 2WD, as I have read that many people have done the same with 4WD buggies from other manufacturers, particularly the XRay XB4.

I will be racing exclusively on astro, so the mid motor configuration shouldn't be a hinderance, as there are 2WD buggies like the XRay and Schumacher that are now in that configuration.

It's got to be worth a try at least? :thumbsup:

[jasonrcb]

We have run the 511 and the 502 in 2wd form,both cars worked ok without being anything special,but add the 201 front end and they both became very good,both versions were ran in saddle pack formation and the results have been pleasing,there will be a 502/201 in shorty layout in the not to distant future,that will be the Cobra KR,until then here are a couple of pics of the other versions we have been running.

[D-StyleNZL]

Well mine has been delivered. Althou, Im still at work so no unwraping just yet.

One thing, which Caster block be better to use. 10° or 12° ?

[SiR_Dave]

Well mine has been delivered. Althou, Im still at work so no unwraping just yet.

One thing, which Caster block be better to use. 10° or 12° ?

12 would be smoother but I would try both... since the new front end has a higher kick up in the front:)

[Aussie Top Force]

In respect of the caster blocks is the 10/12 degrees set in the caster block, so they give an extra 10/12 degrees caster, or are they set to give the 10/12 degrees caster overall, i.e. the caster built in works with the 501x kick up to give the final caster of 10/12 degrees?

If its set in the actual block, the 503 with 12 degrees kick up the final caster would be 22/24 degrees.

In recent pictures of the development cars, see Mark Rienhards cars at Reedy race, he was using the plastic caster block. Does the standard (plastic) caster block come with any built in caster or are they set at zero?

[SiR_Dave]

The carbon plastic ones that come with the TRF503 are set at 12* ... and then add that to the total kick up.. for the total:blush:

[SiR_Dave]

Thanks for the comparison. Might have to get the 12 degree ones for 502 as it has the 10 degree ones fitted.

Has anyone found any setup sheets for the 503 available, or care to share their own setup?

I tried to find info on the setup used by Lee Martin at last years offroad worlds, but I could only find a series of photos of the 511/503 prototype he used, but some basic setup info can still be taken from the photos - http://www.petitrc.com/setup/tamiya/setuptrf503/TRF503_LeeMartin_Chico2013092629/.

I was really looking for guidance on shock oil/springs, and gear diff oil weight. Having never used a gear diff in a buggy before, I am just guessing at the diff oil weight from looking at setups for XRay/Schumacher buggies, but that seems to be anywhere from 3000 to 20,000! :confused:

[tyreman]

Have a look on Lee's website lmracing.co.uk as he used that car at the euros as well

[patez]

Lookin at the Lee's pictures, it seems the building instructions are the same for atleast the shock tower/arm positions and the rear sway bar... I just used the included oil for rear diff, and 10000 for front diff.. Going to test it out next saturday..

Building it from the manual.. there's certainly some thought in the setup there, its not just "put everything in the middle position". Only thing i'm bit concerned about, is the amount of limiters in the rear for bumpy or big jump track.. 501 had a tendency for grip rolling also. Considering that, maybe 4wd doesn't need that much of travel in the back.

Need to drive it first :thumbsup:

[Toon]

I think I wrote that page and I even think that's my hand....and whilst it was a long time ago I am fairly sure the original 501 had 10 degree plastic hubs but the DB01 onwards were 12 degree's....

I also never noticed a difference in handling switching from the 511/502 std item to the alloy one, but with my driving that's no proof!

There's some elusive 10 degree alloy ones somewhere out there too though...

Any of you guys at have our kits... Have you had a chance to run it yet and if so how do you like it..?:drool:

[patez]

I just drove few packs. The track was concrete with carpet jumps. First impression was that the rear was very slippery. So i took out the sway bar (because i haven't used it on my 501 either). Then it it was something like i thought how the car would handle with all the little differences over 501/511.. Gear diffs are of course quite different from the ball diffs.. After a few laps I noticed how consistent they are. So i was able to sweep nicely through a slippery but hispeed corner. The length of the car makes it easier too.

The included setup is propably made for higrip, I'm going to take out the limiters from rear and maybe try sway bar without the limiters. The weights in the rear were definitely needed for low grip. 1k in the rear diff and 10k in the front is propably quite extreme diff setting. But its easy to turn in and lots of steering out of the corner. With the gear diffs and extended chassis its quite easy to get hang of it. Its also easy to understand why people prefer so different diff oil weights. Many setups work and you just adapt to the way the car handles..

I managed to pop one ballstud out of the rear hub. I might switch to the almuminum ones. A longer ballstud screw might work also if i drill it through the hub. (Actually i might try this modification first)

Also i used the short motor screws as instructred in the manual. They were too short and my motor was loose after a few laps. And the other screw had stripped some aluminum from the motor. So i switched a bit longer screws. (I suppose most motors would work with about same length).

I feel there's work to do with the setup. But as it is now, its already faster and more _consistent_ than my old 501. 501 was had a little push but with other setups it was hard to drive smoothly out of the corners... Now with 503 i have more steering but its still easier to drive..

:wub

[SiR_Dave]

Thanks for the info:thumbsup:
So the rear hubs seem to be the week point.. Your the 3rd person I have heard thesis from:eh?:..
It seems like a good starting point for the gear diff oil is 3000 in the rear and 7000 in the front.. :woot:

[Chris]

same problem here with the rear hubs.

i switched back to the alu hubs.

Hey guys, whats the best store to get it from in Europe?

There is an extender included for the rear body mount so the older bodies wil fit, the bodies that fit the 511/502 are a direct fit to the 503, there just is a bigger gap between the body and the rear shock tower.

Proline Bulldog also fits on it straight away, the phantom is designed to go on the longer car so should fit without any gaps.

The TRF501 body also fits but is a bit tight around the motor.

There are turnbuckles included but I haven't driven the car yet so I don't know how strong they are.
So maybe a set titanium turnbuckles.
On most places the silver ballstuds are included, which have never been the strongest or most hard wearing, so you might want some bags of the hardened ball studs.

And maybe the rear hubs, or put a longer ballstud in as the original is a quite short one that is then also fitted on a spacer.

For the rear there is a set of 12mm hexes included with the kit, fronts are the usual 10mm.

Are there any spares available already for the 503 ?are some parts from the previous models compatible ?thanx

[Kimo]

And where did u guys order one? :bored:

Haven't seen any shops yet that stock the spares, they should be in soon i think with stella, rc mart etc.

Several of the parts that you want to have as spares are either the same or they will fit from older cars.

Most of the breakable suspension parts are the same as the older cars, the rear hubs are different but older parts and option aluminium ones will fit.

Front axles with the ring around it are a bit tight in the aluminium caster blocks so they might rub agianst the block when the parts have a bit more slack from use, but they do fit.

Older shock towers will change shock positions but they will fit the 503.

Gear diffs are mostly the same but the pulley is bigger, so that will not fit.
Internal gears and outdrives are the same.

Parts that you might want as spares that do not fit from older cars are just belts, diff pulleys, maybe the center pulley but the old system with the plastic pulleys will fit the 503, think the entire slipper assembly from the 511 can fit into the 503, and a set of shocktowers.

At last i got phantom painted. It fits good. If you're planning to use this body and want perfect fit, you might want to attach the undertray a few mm inward. Or maybe get a proline undertray too. Anyway for me its good as it is. The servo arm ball comes quite near to the body (could reverse it to have more clearence), otherwise there's plenty of room everywhere.. Also don't cut the lines as marked for b44.2 you dont need to cut that much..

All built and ready to try out. With a few extra blue lock nuts added for extra speed.:thumbsup:
Used the 511 body as I had a spare one. it fits well, with pretty much the same cut out lines on the rear as the 511, and leaving a little bit extra on the front, and bending a bit of the material to cover the diff a bit better.
Also used the full under tray rather than the side pod type design, again with a little effort this fits well too.
Found it easier to fit the electrics than the 511, but really wish they would move the slipper nut and spring to the other side!
Also decided to use the alu caster blocks and rear hubs.

The diff pulleys have been available for over a year: 51463 TA06 Front Gear Differential Pulley & Case Set (39T)
You can also get a complete diff thats a direct fit: 54470 TA06 Steel Gear Differential Unit (Front)

I was requested to put up a pic of the bottom of the car to show the whole undertray.
I used the 511 body and positioned it so that the marked cutlines were used at the rear, and the body fit against the rear tower.

In order to fit the tray to match, use the marked cutlines at the rear, and use the marked rear hole.
A little of the rear is tucked under the plastic bumper as is done on the 511.
At the front to get some extra material to tuck under the bumper, just bend some of the plastic to give you the extra length you need (a bit of heat helps here). Then mark and cut.
Hope this helps

Can somebody measure the wheel base on the 503 from the centre of each wheel nut front to rear. I'd like to compare with 502X, which is 280mm with 3.5 toe-in rear suspension (front) carrier and 0 degree aluminium hub carriers.

Should be able to do a pretty good comparison for you over the next couple of days when I build mine up :thumbsup:

You can say that again:blush::lol:

Tamiya Japan.. still has a few spares for the TRF503:lol: just not any front towers until the middle of the month:(:wtf:

[Aussie Top Force]

The wheelbase on my 503 is approx. 287mm with the standard kit setup.

So the 503 is about 5mm longer than 502X both in standard form. I'd say the 3.5 toe on the 502X would reduce the wheel base by a couple of mil. However I find the 502X more stable out of corners with the extra toe.

OK... few more updates..
How about a few new front hex options.. 12mm and 10mm
3mm~3.5mm thickness, so using a Kyosho ZX-5 / Losi 22-4 front rim should not be an issue for 12mm front wheels.. also the offset is only 0.5mm wider;)

Just a quick question....why you using the front hole on the alloy hub carrier?:)

[SiR_Dave]

Had good luck with that location before on my TRF502x... the car reacted a little bit more to my liking with the shorter link :)

[pugs]

I see mate....you might change it back when you try the car;)

[SiR_Dave]

Cool...
I'll try both locations:) chassis length is a bit longer so if might be a different feeling:blush:

[pugs]

yeah try both mate, the car is sharp even with it in the normal position.....noticed you didnt add the rear roll bar...a good move, i disconnected mine in a practice run:)

[Aussie Top Force]

In respect of the front oneway, is the diff locked when under power? I always ran my Egress, Top Force and Yokomo YZ-10s with the one way, but the one one bearing was not in diff, it was elsewhere in the drive system of the respective buggy. Thus the front diff acted like a diff.

[patez]

yes, diff is locked (on power) with the front oneway. the oneway bearing is inside the the pulley.

[AaronR]

How about some other parts that crossover from other Tamiya cars that work with the TRF503 :)
TRF417 Steel light weight outdrives... need two sets to make it work on one diff..;)

Tamiya part 54425 (x 2)?

[SiR_Dave]

Tamiya part 54425 (x 2)?

Yes.. you will need two 54425 since one of the Outdrives is longer that the other... you will need the short side..;) if you wanted to loose a little more weight and save some wear and tear on the outdrives you could also use 51469 x2 as well:D..

I have a whole bunch of other stuff that I have been test fitting and finding out what works from other cars:drool:

[SiR_Dave]

Electronics all wired up and suspension installed :)

Body fit testing up later tomorrow:D

What are thos blue washers between tjhe upper shock mount bush and teh shock tower? Are they a Tamiya Part?

[SiR_Dave]

Yes they are ;)

Part # 53873:)

[Toon]

So, how are we all planning on protecting the lovely alloy chassis from scratches, scrapes, etc?

I have (maybe rather foolishly), already cut up the undertray and mounted the side sections as per the manual. I plan on using the Proline Phantom B44.2 body, which is narrower than the full undertray anyway, so wouldn't have been able to use the full cover. Replacement Tamiya undertrays (#54133 TRF511 body & chassis fairing) don't seem to be too readily available either.

Ideally, someone would produce a pre-cut protective sheet for the chassis, with screw holes. They are available for other buggies, but as the 503 is so new, it could be some time before they are available. I have some carbon-effect vinyl A4 sheets that would offer some protection, but then there wouldn't be any screw holes without a whole lot of precision cutting being required... :(

Will I be able to fit normal size servo in a TRF503??Or just low profile is an option??

Thanks

[patez]

yep you can use std servo. and theres still room left for a small receiver.

[jaq]

I have Futaba R614FF-E, quite small, we will see in a week:)

Thanks

[SiR_Dave]

I'm using a JConcepts standard blank chassis protector sheet on the bottom of the 503.. it's pretty thick and durable... I use it on my other buggy and has lasted over 30 plus practice and race days with out any issues of ripping ;)

Now for the 511 lower chassis protector.. I am only using a small section of it and it will just the back section near the battery trays moved in close as possible and then use Velcro to mount the body and they use the front body mount posts.. it you use the rear mount post they tend to rip a hole in the body since there is really not too much mount too back there.. so I just turn the rear body mount upside down and use the mount as a stopper and let the Velcro in the back hold the body down :)

I've had abit of misfortune....
Got interference at the end of the straight and a car went into my 503 at full chat!
The consequence is.....
Bent chassis
Bent front bulkheads
Bent front hanger

The wishbone only cracked though ;)

Was just wondering if it's possible to get any spares? I can't find any online and rc champ haven't replied?

The only plus side is the car was fast! Was is the right word to be used in that sentence ;)

Any help would be great?

[Roel]

Think the only way to get parts at the moment is from Tamiya Japan itself.
Haven't seen any shop that has any parts for the 503.

Seidel in Germany ussually stocks ALL parts of Tamiya cars, even the things you will probably never break but he still hasn't even got the price for the car itself on the website this time. :confused:

[guinness]

car coming on the 23th ,im ordering front and rear ally hubs,
are this the right spares arms???

Hello, i've got the same issue with Rc-champ last year, try with Super Rajikon.
The e-mail adders is oversea@super-rc.com, send to them the list of spares you need, your data and shipping address, they reply very soon( like champ once )

[SiR_Dave]

CHAMP R/C is on Vacation for about 10 days so they will not be answering too many e-mails..
I have yet to have any issue ordering from them;) it takes about 1~2 days to here back from Masa... if not send another e-mail..
They can get Tamiya Parts for the 503..
