Nice! looks similar to the TT02 I set up for my son! ;)

Here's my finished TT02 with body.....

I am not sure if I am racing this body....it might end up a shelf queen/cul-de-sac cruiser so it doesn't get hammered

Nice :nod:

How much Offset do your wheels have?

4mm. They are the Tamiya FXX wheels

So... last night I built a TT02b MS. How much power can I expect those stock plastic gear diffs to survive? It's got a 13.5t brushless setup in it right now.

Pictures later... But it's a heck of a rig. :-)

Hello guys. Could you explain shock mounting positions, please? I know TT02B and Type S have more positions than the standard TT02. How does handling change? What about on and off road setup?

Not sure about offroad, but onroad using the outer holes make this side of the car more agile. In theory the damper gets a little "harder". If you change the front to the outter holes it will react faster and more directly to steering inputs. The rear position is mostly in a more lay down position than the front. If you use the outter upper hole here, the rear will turn better with the car, but is more likely to step out on the limit. Using the inner holes will generate a more calm and forgiving rear end.
So I would use these positions to fine tune the balance of the chassis, even though you feel these changes much less than on a pro cfk chassis car.

So, I've got a TT02 chassis with a rather hot motor in it. I stripped the ring and pinion to my front diff.

What's the recomended way to hardening the drivetrain to deal with high horsepower on the TT02?

I ordered the GPM steel ring gear... I've heard about using some other tamiya cars metal gear diffs, but I can't find a good set of part numbers for those.

Thank you!

Check nothing was binding. For onroad the drivetrain is strong for most motors. I've even mounted a 5.5t in one :) The only mods were bearings and the alloy prop and cups.

If you want steel diffs the TT01 had heavy steel diff internals. So a TT01 differential will fit.

nope, it was all fine. It's actually a TT02b, with a 13.5 in it... so... i'm asking for trouble. Still, advice is advice. :-) The diff itself survived, the ring gear and pinion have not.

You can use the metal ring gear and propshaft bevel gear from a DF02. The bevel is #5455040, the ring gear is 3454029 and the diff case is 0555104 (the DF02 Gravel Hound manual is downloadable off Tamiya.com).

. Perhaps you're unlucky, I run a boosted 13.5 in my TT02B and the front diff is fine. The rear clicks occasionally but I do drive it with due consideration for it not having a slipper so no landing off jumps under power.

Anyone know if the TT-02R can be adjusted to the 251mm wheelbase so that I can fit the Tamiya 1/10 RC Porsche 911 GT3 Cup VIP '07 body? (made for the TT-01E)

do you have your diffs shimmed? I don't.... I ordered some shims so I can make the mesh tighter. The diff has something like half a MM of side to side play, and that's a large fraction of the tooth engagement...

Yes. From memory it's a single 0.2mm shim. They can vary depending on the mould tolerance of the individual chassis. One of my TT02 cars has diffs shimmed with a 0.1mm in front but a 0.3 in the rear! You don't want to take all the backlash out though or the drivetrain will be too tight.
