I've just run calibrations for these motors on 4s
Sunnysky 2814-11 (700kv) with APC 12x4.5MR props. Current limiter set to 20A
FM-4006 (740kv -same as MT-4006) with APC 10x4.5MR, APC 10x5.5MR and APC 12x4.5MR props. Advance was increased to 20 after losing sync at high rpm with the 10" props. Current limiter set to 15A after toasting a motor and ESC with it set to 20A with the 12" prop. Gotta look more closely at the motor data next time and not assume their listed max current is for 4s.
The closed loop RPM scale has been set for each.
