My P34K is 1.5 yo now and a few times I"ve noticed that one motor is slow to rev up than the other three. As motors start one will hesitate before reaching rev speed of the others. It almost gives the impression that the rotor blade is loose and is tightening on with power, but all props were put on snugly. Once the ac has warmed up further start ups are right in sync. The ac has flown flawlessly throughout.
An ESC timing issue, otherwise?
Thanks.
