I think i got my telemetry at something like 3.74 to get 3.81 after around 4 minutes of sport flying on 300mah nanos. And that is with 75 midstick to 100 at H throttle curve. Pitch in normal is 0-20-60; BTW, 50 at mid stick is too low, the more you bog the motor, the more amp it draws. Spin it up a notch.
What exactly is "head should rotate free" , i unscrewed the screws slightly and tried to move the motor as far back as it would allow, but my geat still "snaps" every time i move it one step. not like my v911 where theres almost no resistance at all in the mainshaft/maingear
