With your transmitter, you'll set up the ailerons with the Flaperon function, and use a "Y" connector or Futaba's MSA-10 Servo Synchronizer to double-up the servos in each wing.

For dual elevators, activate the Ailevator function, and zero-out the aileron portion (unless you want the elevators to operate in concert with the ailerons).

For dual rudder servos, you'll need the MSA-10 Servo Synchronizer to get both servos properly matched. A "Y" harness could be used, but the servos will be slightly "off" from each other, and have increased battery drain and gear wear.

The throttle is set up in the conventional manner.

Put the kill switch on any other available channel and set it to be operated by a switch in the AUX-CH function. The trainer switch is ideal if you're not going to be using the trainer function. That's because it's spring-loaded, and you can have the kill operate when you pull the switch.
