Is there a way you can set it up so his reply's get rejected unless there in the playground section? I have to admit the stuff he posts in here isnt funny or helpful.

DISCONTINUED? Man, where do you get your top secret info?!

Available here too... http://www.tamiyausa.com/product/ite...oduct-id=53951

Lee · #**224** 04-06-2008

BMag, you mention front one way, so why put it in the rear

I still love you though, although your advice is not helpful, it is hilarious, but only because we know your talking crap

ryan · #**225** 04-06-2008

Bmag...Im in desperate need of a pit bitch. I think you would be the best person for the job. How about it??

Just sell the one way and get the correct piece already! I doubt the oneway for the 501X has been discontinued. Go to a different hobbyshop or order online for the correct part if the hobbyshop cannot get the right part in. Use the ball diffs in the mean time. The stock diff balls should work fine if the diff are built correctly. I would also suggest canceling the order for the tugsten diff balls too. More junk you do not need. Get someone that is experienced show you how to correctly build a ball diff that will last. It is not that hard. If you are still new to driving you might want to think twice about using a oneway anyway because they usually make a buggy harder to drive verses using a ball diff in the front. Oneway diffs usually make a buggy have alot of off power steering and make the rear pivot harder on braking because of only having rear wheel brakes. Just a heads up.

Further investing this car I built the diffs tottally wrong...
I forgot to put in the .05mm spacer and the bearings also.
Rushing a kit is not the anwser.

Thankfully the front diff is fine, the rear isnt fine.

I've ran the diffs in my 501x for 8 club meets and only on the last one was the rear diff starting to feel a bit rough.

Thats on the standard diff balls, running indoors with a 10.5 though so fairly easy on them power wise.

At the risk of looking as foolish as B-MAg

I have actually raced a car with a one-way in the back and a ball diff in the front

This was many years ago (late 80's) in Australia when the Mid Optima had a one way option - you could simply take the one way unit out of it's housing and place it into the housing of a standard rear gear diff.

On our slippery track I found it worked rather well - front wheel braking stopped you from spinning out into corners and the car wouldn't understeer out of corners as much.

Not too convinced on how well it would work today though

In fact, I'm sure Gil Losi Jr tested a Yokomo Dogfighter with front AND rear one-ways back in early 87 at some big international event at the Romsey track over there, prior to the 87 worlds?

ashleyb4 · #**230** 05-06-2008

how did he brake.

A

mole2k · #**231** 05-06-2008

Front and rear would be strange, as Ash said he would have no brakes also there would be no diff action so it would be solid 4wd with no brakes.

jimmy · #**232** 05-06-2008

I bet it would be awesome over the jumps tho

bender · #**233** 05-06-2008

From what I can remember the Romsey track was very fast and open dirt track (at least from the pictures I saw), so brakes weren't needed - plus of course the cars were nowhere near as fast as now

And no diff action (at least in the front end) was quite normal back then - both the Progress and Dogfighter used one-way hubs with solid axles. I think the original Cat used this setup too?

DaveG28 · #**234** 05-06-2008

I have to say I do think its worth getting better diff balls for this kit, I've alwys struggled to make standard ones last, and its not the easiest kit to keep swapping diffs on!

Having said that, I tend to run diffs too tight so maybe that's why!

lochness42 · #**235** 05-06-2008

What about using oneway all around?

Is that the standard car or big pulley / worlds car? If you use dust covers (the sticky sort) like I made, then I find the diffs last well. I found the original diffs worked best with ceramic balls, but the bigger 12-ball pulleys were fine with the kit balls.

Good point Jimmy, I haven't tried standard balls with the bigger pulleys, I guess having the extra balls in that version makes them last better! I like as little maintenance as possible anyway though, haven't touched the front diff in @12 meetings, despite rain/dust etc! Its just about holding up still..

I use the sticky diff protectors too, I've had a few come unstuck though so I sometimes end up with loads of crap in there anyway!

Has anyone tried the centre one way yet by the way? Might be a good compromise between a diff or one way at the front?

jimmy · #**238** 05-06-2008

As well as more balls I think the balls are futher out from the centre, so you get more torque. Did you clean the pulley really well before sticking the protectors on? not sure which you have but mine are designed to touch the diff halves which need grease applied to them and it creates a near perfect seal.

That probably explains it, mine touch the diff halves too but although I cleaned the pulley's to try and get them to stick better, I didn't grease the diff halves so the protector is probably gripping on them leading to it pulling off! Cheers for the tip Jimmy, will try it when I rebuild them!

Now that would be crappy right there, Id be like driving my TXT-1
