I am not even sure I did. I just figured wider was better. Used to my VTA car I ran with the wide rear. 24mm it will be then, thanks, I just finished the build. Need to get out there, are enough spec novice guys running on Sundays for a class?

hey guys, new to the tt-02 platforms.

getting ready to build my tt-02s and tt-02r for me and my son. going to be running on black ozite and no additives.

is it safe to say, Tamiya 24 Type C - is going to be the best tire?

Yes

Check with Larry's RC before you buy. I think they have decided on a spec tire for GT class.

yes I think they agreed on the vaterra ones :( I just wanted a different set to try out.

3.9
 

I have done FDR of 3.9 with yeah racing Motor Mount, 75 teeth spur and 50 teeth pinion, 64 dp of course. Works fine with a 21.5 turn Hobbywing for my 5 year old son 😁

hey guys,

trying to return to racing after a multi year hiatus, with these gt3 spec classes.

built a tt-02s for me and a tt-o2r for my son. couple of noob questions.

1. what o-rings do you guys run in the TRF shocks, I put the 419 shocks on the tto2s, and the 42102's on the R. What I thought building a smooth shock and getting the air out, only to realize the leak like crazy and I have to rebuild. my bad! do I stick with the TRF blue- o ring, or any other better?

2. with these trf shocks and the ball stud mounted, you get them on, but now, what's the easiest way to get on and off the car without tearing up the shock? does anyone use a shock collar and screw?

3. Tamiya parts seem like a pain in the butt to order or find in stock at a reasonable time frame. not wanting to wait 2-3weeks for tires, or body or steering knuckle and flange. as much as I support local with all my hobby needs, is there a US online retailer that stocks or supports these parts? I only know of amain and tower, I try to avoid to support local.

what started as a cheap car and class, has me consumed with Tamiya blue and almost the cost of a normal touring car. that's my own addiction issues.

So in a week or two, i'm participating in a race where we build, and run, TT02's for an endurance race.

What should I pay special attention to while building the car? It's a box stock race.... So I suspect I only get to play with lubes and such. I usually swap screws for M3 versus ST screws... I think i'll be limited to the nasty self tappers. Chap stick? Shock oil? How do you suggest lubing those screws.
