My ? Is, can i do this w/ any Rx and the mt-4? Or just a telemetry Rx?
That's of course an option. Yes, you may fry the servo unless it is HV. Don't know, buy it may even be possible to fry the ESC since you're feeding high voltage "back" to the BEC in the ESC.
Don't know if this is possible with other Rx...
