First of all I do not own a sv esc. I am on my 3rd sv motor on my hydra 120 esc and all 3 motors have a horrible vibration at full throttle. I have tried low and normal motor timing on the esc. I have also tried the motors before mounting into boat to make sure it is not a driveline problem. My props are balanced on a magnetic balancer. I am also running fiegao and neu motors with no problems. I had a sv motor about a year ago and had no problems what so ever. I am running them on 4s lipo. Has anyone else experienced this and does anyone have any suggestions? Oh and also this vibration results in excessive heat.
Thanks, Alvin
