Not helping you any but gives me one more reason to stick with my old Futaba. If I want flaps I plug them into the flap channel. Done, no mixing needed.
Actually setting up the flaps does not require any mixing... nor nothing more than plugging them into the flap channel.
He chose to put each flap on a separate channel, which is different than what you did with the Futaba.
The mixing is more complex in this setup because you have a lot of options available to you for a lot of different reasons... you don't have to use this, but he did.
AUX1 is Flaps...
RCPilot: note that he has each flap on a seperate channel.
What I told him is the correct way to do this.
