So the setup is that I have two servos in the wing.
RX is a 5chan with chans 1-5.
Flaperons are ON and second Aileron servo is set to Chan 5.
In Param Chans 5 & 7 have no switch assigned.

Ailerons work just fine. One goes up, one goes down, just like ailerons should. 8-)

I'd like to use the ELV-FLP function to lower the flaps by a % when up Elev is applied.

No luck. ELV-FLP function does nothing (it's not INH and it's set to 50%) regardless of if I set it to a switch or just force it ON.
Flap trim knob also does nothing.

Are these functions not available if the Flaperon function is in use? They were in my old FP-7UHP.

Thanks

Barry
