RE: Flying wing conversion to micro flight
That was probably Jason Nowel. I sent him a PM and asked him to check out this thread for comments.
You do set up the RFFS just like a regular systen to use elevons. The mixing is done in the transmitter. You will need to add centering magnets to each actuator if you don't mount them in line. This helps stabilize the surface when launching and adds flutter control to the actuators.
