You can get both with a 1/8 shaft or 4mm. I would say to run the sidewinder 5700 combo on 2s lipo. Plenty of power for that car. I have a pair of tt-01 chassis cars, and have run a variety of motors. The novak motors do well, as do the cc motors. I currently have a hacker 5s 540 motor on 3s lipo. Trying to break 90mph, best is 74 so far. The feigao 380c motors work well too.
