Recently bought adjustable upper arms for my tt02 drift build, and much to my chagrin when I adjust them so the wheels have negative camber the drive shafts get smooshed, and the wheels become harder to rotate, does anyone know if they make shorter driveshafts for the tt02 or if there is a solution to this problem, thanks.

Are there any o-rings or spacers in the drive cups that you could take out?

Thanks, Do you need to buy new drive cups for those? they don't look like they just fit right in.

The tt02 doesn't have any o rings from stock.

So you replaced the stock with tt02r drive cups and then the driveshafts fit?

Yeah Racing makes M07 33mm driveshafts does anyone know if those fit?

I spent time turning laps last night at our local indoor carpet track that was setup for 1/10th........was able to get some good consistent laps in but that consistency would melt away into unpredictability after a couple minutes.

The main culprit was one of the through-chassis mounts for the steering rack, and while I have the upgraded aluminum rack one of those mounts would loosen and lead to a ton of slop and wander, add in that I had a C-clip in one of my shocks come off and the piston was floating up and down independent from shaft.

Pulled the whole front end apart today and I think I came up with a permanent fix for metal on metal mounting through the chassis which means LocTite is in play.....so that should solve that crap show. I also finally got off my butt and got some nylon washers that were the right size to eliminate the slop in the front A-arms...... rebuilt it all and this could be the winning combo......

Been working on some floor aero the past couple days. Hopefully this keeps some air out of the body!

Thanks 4 pointing that out on the Xpress arms on the yeah so4

Back in June my son and I started running in The Porsche Cup Cars, which uses the kit torque tune motors. Yesterday was our latest race and we were in top place for the A main. My car died right after go.

The torque tune called it quits and spit out one of the brushes which buried itself into the tub lol. Motor has a fan and the case / end bell temped at 100°.

My son finished the race in first but also told me that his car faded at the end of the race.

For gearing, we were running 64/29 the max per TT02R manual, using Tamiya mod 06 / AV gears.

For Tamiya ProSpec class it's not an issue with the 21.5. For CupCars using the Torque Tune I’m surmising that it’s too much gearing.

I took a peak at the TT02R manual and noticed Tamiya had highlighted 64/27 as popular. I’m guessing that could be the max with this motor? 🤔

If I'm not mistaken the 27T pinion is marked because it's included in the kit. Brushed motors have a limited service life. I had suspected that my battery has failed me during a club race, but it was just a bad handout motor. It doesn't hurt to lube both motor bearings multiple times a day on these things.

You maybe right. In my experience, these mabuchi motors have failed me always in the same way.. the copper arm that holds the brush shears off and the brush is imbedded in the plastic of end bell or thrown out from the vent holes. This happened on two black can sport tune in my Sand Scorcher runner, so I stopped running that motor in it. With the torque tune 2 times as well, albeit the first time was when I had it geared (FDR of 3.7 or so) to have my son 7 at that time compete in our club class for VTA.. so it was geared very high and the motor died by days end.

I didn't expect it to happen in a TT cup car class using the Tamiya gearing (FDR 5.74). But to your point, I have ran this motor now for 5 race days for a total of 18 heats. Never cleaned it and never oiled the bearing. Something to consider for sure.

For next race I plan on trying 27t (6.16) to see if it makes a difference and see how long the motor lasts. Track is super tight so it should be ok.

I've been out of racing for 10 years or so. Getting started in VTA racing again and want to use a TT02 because my intent is to move up to TCS Spec 21.5 as my.skills improve.

Question is which model to start with- TT02R or SRX? Which will be more competitive as I move up and why?

Thanks, fellas!
