Will 54649 diff lock work with these new RR differentials? I built it for now with the 1 million fluid and will try it out at least, I have 6MM clamp on hex for axle, the weird rotor combination ones that come with kit appear like they may be 7-8 MM in width, hard to measure exactly.

Looking at manual for a regular R with dogbones the outdrives are MB16 #19804237, the RR they RR MA20 # 19803157. S different again, but the R and S have a flat spot on outdrives that engages the differential. The RR you do not, its just round with a pin that engages the bevel gear of diff. Will need to verify more before buying diff spool.

What spring you think I should put on these CVA's, I started with 50wt oil all around, 3 hole piston front, 1 hole rear but the silver springs feel pretty soft to me.

The CVA 4-pack TT02-specific kit with the black yellow-marked springs, built as per the instructions are a good starting including the supplied oil.

I have the CVA's they come with the RR, looking for stiffer springs than kit silver. Do you have part #? 54797, 53333, 84324?

If they're the same as what's supplied in the 54753 CVA kit, then yes.

Where are you running? In door or out door? 50wt is a big high.... 40 wt for out door and 45 for indoor is what I usually do

Indoor black carpet. I had the oil, I can adjust as necessary.

Got it, thanks. Technically speaking o rings in shocks would violate novice class rules, no shimming allowed, but I get what you are saying. Setting these things on a TT should be interesting, there really is not any part that does not have a degree or mm or more of slop in it be it camber, toe, droop etc.

The harder two variants of springs included in Tamiya spring set 54797 are very close to Xray 2.5 and 2.6 springs. That should cover most tracks.

Thanks, 2019 Novice allows any Tamiya Hop Up., but no shimming. Interestingly since you can use any hop up, I believe the torque tuned motor spins a a couple thousand RPM faster than the new Reedy Fixed timing 21.5T, the novice cars could be faster and built to the exact same spec as GT pro spec class.

They might as well make GT Pro spec the torque tuned motor now and save everyone the hassle of having to buy an expensive reedy motor and esc. Then a novice could truly move to that class easily.

wtcc, NICELY done !!!

I have 2 sets of premounted tire Type C #47351 which are 24mm, is there a 26mm TYpe-C premount, I can't seem to find. Will 24mm Fr and Rr be a nice set up?

Ran into this myself, and I am not having luck finding 26mm Type C tires

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.

Sadly, multiple motors isn't going to be an option. but a low voltage bath type break-in is probally in the cards.

I appreciate the advice!

ANYONE?

I think in reading the rules that TRF shocks are legal for the Spec Novice Class, but I don't think they are legal for the Pro Spec class if you are running in that. I assume your son is running in the Spec Novice Class. I would look at two articles for some tips about setup and I think there is a discussion on shocks and "o" rings. Based on my experience with young drivers and myself, I would buy some extra steering uprights. They break easily and local tracks run out quickly.
