I can give you some tips if you are set on the TC02:
-the top plate, the one that connect the bulkhead and the steering system to the chassis needs reinforcement around the rear screws, it's too thin on that place and I broke one easily.
-the bottom plate breaks on the kickup.
-maybe the ball diff was updated, if not then it would need some work and Kyosho parts, the slipper needed a spring change.
-the rear inner ballstuds should be vertical and could be better located.
-you can't tune anti squat and inboard rear toe.
-you can't use tall(~26mm) lipos.
-front arms break usually at the inner hinge pin.
-wear is fair, steering rack, CVD's and arms are the most critical parts.
Drives well but *I* really think it could be even better on that regard.
