Has anyone here purchased a TT02D w/body? Going by Tamiya website it comes with the TBLE-02S ESC but on online stores they say it doesn't come with a ESC.

Default What gives?



So I just finished building my all stock TT02 expect for bearings.

I noticed that it understeers when turning right. I checked for binding, steering endpoints are equal and everything seems to check out all right.

Is there something that I missed? Can anybody kindly help me please?

How about posting a picture of the assembled chassis? A picture of the link between servo horn and steering bridge will confirm or clear one possible problem

Here is the picture sir.

I installed adjustable turnbuckles on the said link from the very start in anticipation for fine tuning.

Still it has that oversteering when turning right.

Check your left rear damper, ensure that the piston slides without binding. Drain the oil if you have to. Try switching the rear dampers and see if the oversteering transfers to the left side.

Also, the servo horn and the servo link must be at 90deg to each other otherwise you will have uneven throw. It can be corrected at the radio but I prefer correcting the problem at the root

Servo link is at 90 deg. Throw is even. My dampers are the stock "pogo sticks".

I will look into replacing my dampers with oil filled ones.

Quick question for you guys.

What's the best way to "widen" a stock TT-02? In my son's kit, I noticed there was a pair of extra wide plastic wheel hexes. Do you need different stub axles to make those work? When I install them, there is not enough thread to bolt on a wheel.

Thanks!

Quick question as well...

Does anybody have a list of parts to convert a regular TT02 to a Type S?

Thanks!

List of parts is here ( https://www.tamiyausa.com/product/rc...3#.VVazylVVhBc ) You probably need almost all of it except the lower deck, G, D, B and A parts trees.

I like my Type S so much I wanted to convert my other TT02, but figured it was easier just to buy another kit at $99.

Thanks! Very helpful link there. I was also thinking that it would be more cost effective to just go and but a new kit as well.

I'm just curious, where are you finding type S for sale at that price? I want to do a conversion to Type S suspension however after seeing your post, buying a complete kit may be a better answer to my quest. Thanks.

I got my Type-S from RC Mart for $99. It is still listed at that price but it reads "Out of Stock."
A conversion might be cost effective if one had a TRF417 with a broken chassis or something like that. I just think the cost of all the suspension pieces would add up. You need the little spacers, the correct screws, C-hubs, bearings, drive shafts, suspension pins, all the little bits to shim the suspension arms, all the balls for the shocks and more shims, the shocks themselves (somewhat hard to find short ones), balls for the upper arms, the upper arm turnbuckles and cups, F & R shock stays.

I really like my S-type. In terms of balance, it works out better side-to-side than my TB04 Pro.

I just saw this "Coming Soon" on the Tamiya site, so S-type kits should still be available.

TT02D S-Type Chassis Kit - Drift Spec #47301

Looks like TT02 S-Type with drift tires and motor heat sink.

According to Qatmix this will be the highest spec TT02 once released.

Here's the link. Just scroll down. http://www.thercracer.com/2015/05/al...ouka-2015.html

I am looking forward to having this kit.

I did my DIY conversion to S. It is not complete though. I'm definitely buying that drift S-type when it reaches the LHS.
