I just finished this build and after the 4th ride I noticed that there is a humming/vibrating sound(not good at describing sounds) coming from the motors.
dual flipsky 6355 motors that I used for more than a year with no issues.
fsesc that I used for more than a year with no issues.
bench test with&without belts attached. can be heard when the motor reaches full speed.
There doesn’t seem to be any performance related issues. acceleration and breaking are smooth.
What do yall think? Am I just being too paranoid because its a new build?
