Newby help.

[Batfish]

Hi all,

Joined the other day, decided to get back into club racing.
The last time i had a Kyosho inferno 10 so yeah a few years ago.

Just picked up a Schumacher cat K1 aero off of eBay,
Quite a few upgrades with it.

I need help with a motor setup, the track here is outside only and plenty of dusty sections and usually wet grass.
I'm looking for something that will give smooth control and not flat out attitude
I'd rather learn to drive the thing again before going for it.

That said, I have been looking at Orion vst pro motor, Orion R10 esc and battery wise i'am unsure, the car comes with three chassis incl the forward motor option which its sitting in at the moment.
Still waiting for the car to arrive.

The specs are as follows.

In fact here is the full run down.

Schumacher Cat K1 Aero 1/10th Off Road 4WD Rolling Chassis (No electrics)

Absolute Top Specification Car maintained at any expense and run successfully for a full seasons racing. Comes with the following option parts over the standard kit...
• Forward Motor Conversion (Carbon Fibre Chassis)
• Normal Kit Carbon Fibre Chassis
• Optional Alloy Chassis
• Front Alloy Yokes
• Front Alloy Pivot Blocks
• Rear Alloy Pivot Blocks
• Gear Diffs Front & Rear
• Alloy Transmission Housings Front & Rear
• Rear Alloy Hubs
• Newly Fitted AVID Bearing Kit
• Cougar SV2 Rear Wishbones
Also included in the sale are the following items...
• Professionally Painted Bodyshell (New)
• 2 Sets of Big Bore Shocks
• Core RC Spring Set
• Spare tuning parts (Roll Centre Adjusters, Anti Rollbars etc)
• Numerous sets of Wheels & Tyres
• Many New in pack spares (see photos)

Any help would great.

Kindest regards
Adam

Welcome back to RC. I returned last year after a 25yr lay off.

However, I couldn't specifically see a question in your e-mail?

If you were just generally getting a feel for the electrics, then certainly Orion stuff is good and if you get anything above the basic spec you will be able to programme the ESC to give you smooth control for the slippery stuff.
I use Speed Passion, but Orion stuff is good

Hi Mate,

Thanks for the welcome.
Sorry should have been more specific
Looking for suggestions/advice on the
Motor, Esc to go for and how high or low with regards to amount of turns.

[mattr]

I think the question is what motor to get to learn how to drive again......

TBH, I'd be looking at something in the 8.5-10.5 range. Start off with all the toys turned off.
Keep adding boost and turbo until motor temps are silly, then upgrade to a "proper" motor, lower turn than 8.5. And start the process again.

You'll need an ir temp probe, and a selection of pinions.

Second hand motors, or hobby king will see you right to start with.

Might also be worth downloading a couple of setup sheets from petitrc and setting the car up sensibly for the track you are using. It's quite possible that the seller has either been driving high traction or carpet, or has just thrown the car together to sell (shocks and diffs not set up properly). Having a good motor won't help if the car won't go in a straight line.

Hi Matt,

Say I go for a 10.5T
Would i be better to invest in a say a top spec esc 160amps now rather having to change out later?

Boost/Turbo?? I've only ever used Nitro in the past bud. New technology and a learning curve this electronics.

[mattr]

If you've got the cash, get a better one. Rather than one you'll be pushing to 10/10ths all the time.
I'm using Speed Passion Reventon Pro, which will do all I want and more.
Boost and Turbo describes how the ESC adds the timing to the motor. You can have fixed (done mechanically by moving the end bell, or electronically by advancing the timing, it's the same amount throughout the rev range) boost increases timing through the rev range, faster the motor goes, the more timing it adds, some ESCs you can put variable or sloped "rules" in place.
Turbo adds the timing after a time delay at wide open throttle, i.e. after 0,2 sec at WOT, start adding 1 degree of timing per second.

There are lots of variables and versions depending on your ESC , so probably best to buy one, read the manual then start asking questions. You're unlikely to buy a bad one, as there aren't many left.

[luniemiester]

Personally if your new to electric its easier to just buy a 6.5 motor and not worry about boost and turbo. This will be quick enough while you get to grips with the car and can take boost and turbo later if needed.

Even now I still spend half my day playing with these settings where as a "normally aspirated motor" is plenty fast enough for now. If it's too quick you can just turn down the epa on the throttle to suit. If you find you need more speed then add boost/turbo afterwards

My lad who's 8 runs a 6.5 unboosted on 80% throttle and its plenty quick enough for him and if he gets to that stage where he needs more than 100% the the boost option is available with out changing motor

[Batfish]

Thanks Buddy,

I bit the bullet and bought an Orion R10 pro with the card.
Was unsure of motor so started reading through the forum/net.

I have a Graupner des 806 b servo
6v speed .13
Torque 10kg
Holding torque 19kg.
I was going to use this but something tells me it won't be enough for the task
Since other are somewhat more powerful.

Any suggestions,

Thanks again
Adam

[mattr]

FWIW I found the 6.5/EPA combination to be quite abrupt and not very nice to drive. You may be ok with it.

Servo should be ok/borderline, unless you crash a lot.
I'm using a 15kg servo. But I do crash a lot.

[Batfish]

Hi Mate,

Going Team Orion esc and motor.
I found a cracking servo but £100 I'm still sitting down after seeing the price.

Purchased new Rc gear too, Futaba 4pls with 2 Rx both FHSS.
Thanks again folks for the suggestions and answers

I also found a low turn motor with epa reduced, unpleasant to drive. Maybe use the expo to reduce the initial acceleration rate if this is the route you choose
For what they cost, I'd start with a 9.5 ish and the use boost as advised above to give a spurt on the straights if needed. You can then replace with a lower turn if needed. It is prob worth having a few - I use a 7.5t for outdoors and a 10.5 or 13.5 indoors, depending on track, but I have some boost set on my speed passion reventon pro ESC.
The savox servos are pretty good for ~ 50-60. Typically most use the 1258 normal size or 1251 small. I've seen it said that the 1251 can strip gears, but I've not found that to be the case.

[Batfish]

Just wondering
I have been looking at Futaba Bls 152 servo is it really worth the money?
And Hitec 7950/7955
I did look at Ko propo 30101 but I missed out on one, must have been new old stock.
Never used Savox before maybe I'm just biased towards Futaba and Hitec

I purchased the Team Orion R10 pro esc
And will purchase one of the vs motors, is it worth buying one of the mod ones? It's only £10 more.

Best regard
Adam

[Ashlandchris]

Gut feel can almost never be changed, but I have used Savox for the past year and they've never let me down. I was given a low profile 1251 with stripped gears by someone and I swapped the gears and it has been running in my YZ2 since Jan with no probs.
I'm told "Xpert" are top notch too, but never had to venture that far yet

[Batfish]

Hi Chris,

Thanks for the suggestion, having a look at xpert servos at the
Moment, must admit there not a bad spec or price.
Noticed another make, Radio shock?? But no uk supplier?

The Futaba 152 is £130 a lot of cash for a servo, I would understand if it was 1/8 or 1/5 scale.

Many thanks to everyone coming up with tips, suggestions and recommendations.
Please by all means keep them coming.

Regards
Adam

[Batfish]

Found a Futaba S9075SB for a good price £66
0.14 at 6v and 30kg at 6v

Should be enough for the Schumacher k1

[Mivys]

Hi batfish, I'm just getting back into it after a good 20 year break - things have changed a lot! Last time I raced I was on a reedy pink dot in a procat! Just looking at a K1 myself... Always liked the cats... Good luck with your start up

[Batfish]

Hi Mivys,

Like yourself if have been out of the Rc cars since 1990's
I picked up the cat K1 with a host of upgrades.
Spec I'm using for it,

Team Orion R10 pro
Team Orion Vst2 pro 6.5T or 5.5T unsure if standard or mod version motor.
Orion saddle packs
Futaba servo listed above, although the Savox 1258 that was recommended is a decent servo, there is also the xpert servo too.
Futaba Plks-4 with telemetry Rx.

The recommended tire for the track here is Schumacher mid spike yellow insert
For dry use and for wet just the same but green insert apparently.

I went a bit crazy and picked up a Mi5 with mid mount chassis etc too
but my mates needing it so i'am in talks with a chap at the moment for a Mi5 evo

Good luck with which ever kit you go for bud, the X-ray Xb4 seems to be a good kit. If your stuck ask the folks on here, a lot of free knowledge.
Let me know how you get on and which kit you go for.
