Almost, "ALMOST!!" any modern electronics can be adapted to another use if the builder has a little electronic knowledge and a bit of imagination. It is common practice for those of us who have several types of radios to use them over and over again if the original model has been reconverted to kit form. I am not too familiar with the radios included in the RTF airplanes but I do note that a warning is usually given that one should check with the nearest RC club before using the radio as there might be interference. I don't really know if this is because they use other than 72mHZ or because the AMA recommends at least a 3 mile separation between flying sites. An aircraft that uses elevons sounds like a good exercise for your imagination. Go for it.
