RE: 7CAP 5chan RX Flaps?
I needed the 5 chan RX in another model. So I replaced it with a 6 chan.........Guess what - - - - If you place the second aileron servo on channel 6 all the mixing functions return. I can now have my ELV-FLP function on a switch and it moves both ailerons just as it should. Snap flap works as long as you leave the second aileron servo on the default channel 6.
All the best

Edit - don't forget to ENABLE FLAP TRIM and set it to 0% - 0% or the TX channel 6 knob will work one aileron. That would be drastic if used in the air.
