Test it out

i will. Time is very limited for testing. I get a short time each week to.play hense the research. Are you using the trf ahor springs to get the ride hight?

Ran my TT02 S on carpet for the first time this week.....what a pig. While I drove it to second place, it was the hardest I've ever had to drive that car. It pushed hard in corners, the lack of sway bars was very evident in the high speed corners. I think I've come up with a solution that will allow me to mount sway bars (I'll post it if it works)

This was my set up in usgt for carpet

Ride height 5
Droop - 2,5 over ride height in front and 1,5 in rear
Camber - 1,5º all around
Front toe - 1,0º toe out
Dampers TRF419 big bores
Shocks Muchmore 400 wt
Springs Muchmore X springs Red front (firm) Pink rear (medium)

Diff - Front epoxied / locked, Rear 10k (using my diff mod in this post R/C Tech Forums - View Single Post - Tamiya TT02 Thread

Car was extremely competitive. I stopped running it because of the rear portion of chassis breaking when rear axle stud would catch a pipe and break... I even broke the hardened chassis this way..

That's almost a mirror copy of my setup. I'm running a ball diff in the rear, locked in the front.

The only major difference is dampers. I'm running TRF black coated with stiff front springs and med rear springs.

This was on grey CRC carpet with SXT 3.0 sauce on Gravity USGT tires

thanks you thats great info, realy appreciate it. I rebuilt the shocks last night (mini CVA) with a some orings to reduce my droop, im still not down to 5mm ride hight so when the springs arrive ill try the medium rear and see if that gets me where i need to be. i rebuilt with a 35wt oil with the 1 hole piston. I have around -1.5 up front -2 in the rear with unknown toe, im guessing at around 1deg. also running heavy oil in the front diff, this did help last week. thanks again for the info, ill see how this setup works :-)

thanks again.

Got a box stock TT02 for my son to run at TCS events in novice. Car ran fine in practice on black carpet. First qualifier got some traction roll, so between quals I super glued sidewalls. Second qualifier car ran great when making left hand turns but would spin out on right hand turns. Could not find anything mechanically wrong with the car, looked at diffs, dogbones, etc...nothing-even tried different tires with same result. In final car did same thing. Got home and still can not find anything wrong with car. HELP! WHAT IS GOING ON? THX

what tires were you running?

...I'd also double check the bearings in the outdrives, as well as verify your steering travel is the same left to right, lock to lock.

Any secrets on how not to pop out dog bones (besides not hitting anything) for a box stock (except for super mini shocks and aluminum motor mount) car?

Kit stock rubber tires, but I tried a different set that someone loaned me with the same results.

I am thinking that it is in the drive train because going straight and turning left there are no problems

Bearings are fine and steering is the same left and right

Unfortunately no tricks or secrets, just have to replace with 53792 universal shaft assembly or equivalent

No testing this week. Damn weather. Question on motors now.
Im running a sport tuned which is about the pace we all run. Id likento go brushless for increaded run time not more speed. Would a 17.5t be roughly in the same region as the sport tuned but give increased run time?

Thanks

I could be wrong but I think they range between 23t and 27t. Do you have a model number you can provide?

I think a 17.5t motor would be much faster than the sport tuned.
