I have been toying with the idea of using the 5th channel to trip a relay, making the on off of the heli remote. that way you can turn on the transmitter, and then from a distance you can hit the gyro switch, and power on the heli. just so long as you don't accidentally hit that switch in flight, that would suck. still I might have to do that. just as something to try.
If you do that, you'll need separate power to the receiver.
But the point is to have the power completely off until you're ready so you don't have an accidental throttle up from bumping the radio, glitches etc. If you control the "power switch" from the radio then you haven't eliminated this possibility and IMO defeated the purpose of having the power off. What you're proposing isn't really any better than using the throttle hold switch.
If you have an extra channel you want to use for something, try using it to switch lights on and off or retractable gear or something
