Hi john_s3
I am not familiar with your radio, but your last description hints a lack of understanding. I have used elevons on my plane, a flying wing. My radio is a Futaba 2.4MHZ. It is an early computer radio. To use elevons I have to use the manual, which describes exactly what to do. If your radio does not have this feature, you can purchase an elevon/mixer, or something named similarly. I used one before I had a computer radio. It worked very well.
