The problem with this motor is that it has too much vibration. On my F550 it seems to work OK, when I sandwich the flight controller between moon gel slices, but I did the same on the 3D printed quadcopter, and the moon gel cannot keep up with the vibrations, and the quad twitches, and shakes... it flies... but not smooth. I can actually see the arms of the quad vibrate at high frequency while it's flying.
I tried to balance the motors, and it removed a little bit of the vibrations, but not enough. (Props are balanced)
I tried to find an equivalent motor, but most I find are for 3S battery, and I am using 4S battery...
Does anyone know a good quality replacement for this motor? Similar size, power, 1200kv, 4S ?
