Did you swap out the ESC's from left to right to make sure it was isolated to the ESC?

I have never heard that sort of beeping so I wonder if you just have a partial failure of your speed controller. But there could be some interplay between motor/wire/battery combination. Either way, even if you isolate it to the ESC, the ESC will have to be replaced IMHO. But trouble shooting like you are doing at least prevents you from replacing the wrong component Good luck and happy gremlin hunting.

Pulse Width Modulation (PMW)? I'm sure this changes per load put on the ESC.... if I'm not mistaken. That's why you get a simple "putter" motion and not a rotation on the EDF...

Other possibilities include over voltage for receiver's BEC, Interference from high amp / high voltage battery cables running close to signal cables for the receiver.


Just some thoughts...

Flex Sir the high foltage wires running next to the servo lead from the esc to the RX might be a winner I will do some tests wednsday when I dive back to work. . .I'm on a break today & tomorrow.

Thanks Boss!
