Motor twitching

[Mulisha]

Just wondering about why motor is twitching happens at any throttle position. It's only on air boat with 2632 3400kv on 3s lipo. Esc is traxxas one out of a mini slash vxl, meant to be waterproof :P. Checked all wires nothing has de soldered is it my speedy, I have had it upside down a few times lol.

Sounds like a radio issue maybe that particular rx

I thought so its hk 2.4 but grabbed another hk rx and even spektrum rx and it still does it. Tried another motor too and it stutters as well.

It turned on and was working then I was driving it on the concrete and hit a bin then it went all silly.

It could be "cogging" (google: brushless cogging) but if it worked fine before, probably damaged it with your 'bin adventure'
