I have a setup using four Novak Super Rooster ESC's and a Futaba T6EX transmitter. Everything is working great! That is, until I turn off the power switch on the transmitter. At that point, one of the ESC's LED's goes out and the motor starts turning. This continues until I turn the transmitter back on or if I disconnect the batteries.

Has anyone seen a problem like this? I switched a couple motors and the problem stayed with the ESC and not the motor, so I think the ESC might be faulty. I have gone through the one touch set up a few times, and it goes well every time, but I still have this strange problem.

Any tips would be appreciated - I'm new to this so I hope I have given enough information!

You should probably post this in Radio and Electronics section...

Reposted as per your suggestion, thanks.

Well for starters I would recommend switching off Whatever your running 4 ESC's in first b4 you switch off the transmitter.
