Its a very common issue/flaw with the TT02. The stock set up is awful You can upgrade it by going to the Type S Bell Cranks and the Hi Torque servo saver. It really depends how much you want to spend (if anything). On my TT02R Runner, I dont run the servo saver I just run an alloy horn. Unfortunately TT02s are just known for having terrible steering. You can can turn the dual rate down on your radio to help the sensitivity if your radio has that option.
@Lone-wolf I dont think OP meant to post 8 times, the forum seems to be glitching quite bad today =/
