Very ture.... 新手 buy tt01 la. I have a new hand friend. Bought a TB02 without telling me. He doesn't know how to use shim at the spur gear, damaged both gear after a few runs. Messed up the ball diff, unbalanced setting and angles
TT01 is better. Nothing to set meaning less chance to mess up (for new hand). 4WD much easier to drive. If you get a F103GT, you will give up R/C veryyyy soon.
