Aurora 9 Flap to Elevator Mixing

Hello all,

I own an Aurora 9 radio and I want to use the flap function but I am not sure of the concept behind the programming of elevator trim with flaps. Let me explain.

My airpalne needs down elevator trim mixed with the flap function to prevent balooning when the flaps are deployed. Currently, full down flaps will point the airplane's nose straight up.

The flaps currently are activated by the left slider switch and there are about 10 postions (clicks) before 50% flaps and about another 10 positions (clicks) before the flaps are fully deployed. I can put the flaps down to any one these 20 different postions, which gives me several flap positions, not just three-flaps up, flaps half down, flaps fully down.

Hitec has created a built-in screen for elevator to flap mix. My question is -must I put in a separate percentage of down elevator for each of these 20 positions or will just one down elevator percentage (foir example 10% down elevator) be proportionately mixed by the transmitter at each of the 20 flap postions?

A secondary question is what are the exact steps to input and activate the elevator percentage. I tried to do it once and all I got was a permanently down elevator.

Thnks for your help.

Try using the camber mix assigned to the left slider, it lets you set the flap, ailerons and elevator. This is what I use for the Fun Cub but also set it up in Glider mode and use B-Fly mixing tied to the throttle which lets it come in automatically when I lower the throttle.
