JetSD,

I've seen the servos "chirp" when the switch was turned off, but not if the Tx was still on (which it should be for safety).

I've, never seen the servos rotate enough to go from an idle condition on a throttle to even 1/2 throttle (let alone full throttle) when the Rx switch was turned off.

Thanks for the warning. I will be watching for it on my aircraft.
