Drove my TT-02 yesterday at the club and the car is still getting better.
I'm using a 21.5T V3 speedpassion motor along with a cirtix club stock esc.
This is a rather slow combo as i was driving an FDR of 4.68 (90T spur&50T pinion).
I was just able to keep up with the other guys who were running a carson cup motor with a fdr of 6.28 (58T spur&24T pinion combo in their TT-01E cars)
There was another guy with a TT-02 who was even running a FDR of 7.28 (70T spur&25T pinion) with also a (brushed) carson cup motor and the speed was just the same as my car.
The car is going good but the motor/esc combo is a bit slow, the only positive thing i noticed is when the car comes of the track the motor is after running for about 20 minutes only 56°C warm (not using a fan to cool the motor while driving)
Though it's a good combo for an endurance race
