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!

#1 rule in R/C, make sure your transmitter is on before you turn the car on, simple as that. Follow this rule and you should have no problems. What you are seeing is normal really.

What about A failsafe? does your transmitter or esc's support A failsafe or a fallback position if the receiver looses the signal from the transmitter?
