Hi all

I have now finished my boat and I am just adding two esc’s one for the main drive power and one of the smoke generator, and I have several esc’s knocking around so tried a couple out.

I tried a Mtroniks one and find at low rpm it makes the motor give off a sort of high pitch whistling come whining noise, (most distracting,) and then I tried the electronize one it doesn’t do the whine or whistle, but makes the motor click or creak at low rpm.

The main drive motor is a gruapner speed 800bb torque, and the smaller one is just a 12v dc fan.

Any info or advice on how to stop this is possible, or an esc that doesn’t do it would be much appreciated. I put lots of effort into getting this really well detailed for appearance when on the pond, and having it whine and whistle or creak was not part of the plan.

Many thanks

Don
