Quick question... Planning to run 1900kv on 4S at Norcal Hobbies. What pinion gear tooth should I get. 17T? 18T?
18t, no timing, adjust from there. Using an RX8/T8 1900 (and no current limit), I come off around 120-130 on the ESC with no fan, and 130-135 on the motor with no extra heat sync, pack after pack. I just put a couple holes in the obvious front facing spots on the body to push air in for cooling, and on the back side to let it out.
