My current setup on 9CH Tx:

Mode Glider 1
Flaperon On (2nd servo on channel 6)
Trim Mix On
Start OFS On (I use this when in lift)
Speed OFS On (I use this when escaping sink)
Butterfly On (modulated by throttle stick) (Switch C - Up)
Elev-Flap On (switch C - down)

Programming launch preset:
I want to program a preset on switch F for launching a DLG glider. I use PMix 1 ofst to raise the elevator. I wanted to use PMix 2 ofst to reflex (raise) the Flaps. But I tried both FLP1 and FLP2, and the Flaps did not move on activation (the PMix 1 elevator is operating as expected).
What am I missing ?

Programming Butterfly:
How can I use PMix 6 or 7 to give me the following:
Throttle stick in full throttle position: Flap up
Throttle stick at 15% throttle: Full flap down
Throttle stick at throttle cut off position: Flap up -> this is to protect the flap servos on landing

Thanks for your support.
