Question
Why a BLDC motor stutter in full throttle?

Why a brushless motor stuttering with no load?
I am trying to figure out why some of my motor stutters more than the other.
It stutters at 3/4TH than fine at full throttle. Some motor will start to stutter at 3/4 and continue to stutter to full throttle.
I notice this stutter more with the smaller high kv motor with NO LOAD.

Too big a prop (torque),
Battery not up to the job
Poor connections/connectors between controller and motor, or in the motor. Can fry motor and/or controller! See
Motor stuttering? Won't run? Read before asking.

Voltage? Controllers? What motors? Kv? Prop? Current?

thanks ron.

I dont know if this matters but this is a turnigy 3536 motor. rewounded to 2200kv with very low (2T) turns. 12n14p 2T Y with 2x1.2mm wires.
With or without load it still stutters. Brand new lipo 4s, New ESC. All solder joints are good.

Found the problem. It is the ESC. Seems Yep ESC don't like high pole motors. Different brand works fine.
