I always set up my planes so that the same switch does the same thing on every plane......I also fly with a 10C.....I don't have my radio in front of me so bare with me.....My ignition kill is through an optic kill switch set up on the inboard switch on the face of the transmitter on the right side...not on the top of the transmitter but the face....my choke servo is the switch next to it on the face of the transmitter...figured if I needed to kill it in a hurry and missed one switch I'd hit the other...
But that is how I do it....you set your transmitter up to suit you....but try and set all your planes the same way....or one day you'll reach for high rates thinking you're flying plane B, and kill ignition cause you're really flying plane A
