    pinion size

    What size pinion would be a good starting point. this is my set-up trx-4 sport 39t spur , 550 21turn trailmaster sport, 3cell lipo with hobbywing 1080 esc. looking for good controllable low speed and good drag brake. thanks for any suggestions.

    I'd probably go 15t-18t at most. Depending if you want a bit of extra speed.
