RE: Flaperons or Differential Ailerons?
I'm positive the Hitec 7 can set up these functions. I have a Hitec Prism 7 which was the predecessor and it would set up both modes ok. Look at the manual for your radio and look for "flaperon" premix function. the right aileron is usually plugged into channel 6 and then you need to set the direction and throws so they both act as ailerons and flaps. You'll need at least two P-mixes on your radio to set up for mixing the surfaces with the elevators.
