I used 1s hobby wing 120a with 6.5t, mod firmware. Speed is no bad. My friend tested stock firmware with same esc and turn and tune down a lot of boost and turbo, it is still much faster than mine.
low-turn motor in most 1/12th will leave you having to replace the tires/parts quite often. that running costs more expensive. Timing + mid-turn motor had better for regular playing.
