However... I want to upgrade my belt standard 10t pinion and I donīt know if I should buy align or esky pinion.. Does the align pinion even fit the belt engine and main gear?
My second question is about flight time.. I know that more teeth in the pinion makes the main rotor spin faster (more head speed) But if I adjust and lower my Tx throttle curves so that the RPM is the same as with a 10t pinion with a 11t (or even 12-13t). Will this save battery and result in a longer flight time?
That do you think?
P.S. Which Align main shaft fits the Belt (plastic version) There are several to order and I donīt want to get the wrong one.
