Programming flaps.
 

I have a tactic 650 6ch 2.4 radio. I have recently purchased a opterra delta wing fpv plane. I'm useing the tactic 625 rx in it. Flies great. Somebody hand launches the plane for me. No problem but I want to do it myself. It needs up elev on launch. About 1/2in or so. It flies on elevons so it has a servo on each wing. Is there any way I can program a switch on the tx to switch it so it puts both ailerons up upon take off . The switch it back once flying ? Sort of like flaps but this gives me up elevator instead of down like flaps do. I don't know how to do it. If it can be down. The only other way is to trim up upon launch then trim after flying. Is there a way I can overcome this. Thanks for any help guys. Good fly 'n......Ron

No need to answer ..... thanks. It cannot be done with elevons.
