I always set my planes up the same way. I use the throttle to kill the engine and the choke only for starting and as emergency kill.

Futaba 9c allws you to set up a 3 way switch as hi-low-off. Start on hi, taxi and fly on low, off to kill.

I also use a Spektrum DX7. It has a neat feature you can enable that will remember the last throttle trim location when you hold the trim down until it is fully closed. The next time you trim it up, it returns to where you had it. So find a comfortable idle RPM, then trim all the way closed to kill the engine, then let it jump back to running position with one up-trim click.
