I'm building a Jerry's Big Boy that will have split ailerons using 4 servos and 1 servo ea on the elev, rudder, throttle. I plan to set this up with flaps, airbrake and a crow mix.

I want to match up all the aileron servos for full length aileron control when not using the crow or flap mix. What is the best way to do this?

Hope this makes sense.

Thanks

Jeff
