I bought the FT Mighty arrow and finished building it and when i got it to bind to my Flitetest radiomaster pocket controller, i selected FT Wing but i cant seem to figure out how to set up the elevons. I've only set up normal controls for our Tiny trainer. What do i need to do to get elevons set up? Right now when i pull back it turns and when i push left or right the elevons go up or down like to gain or lose altitude. Are there any good videos on how to set up those controls? Any help would be greatly appreciated!
