Use a FlySky or Turnigy receiver connected to an Arduino and motor shield to drive two servos.
This code builds uses the excellent FlySky i-bus library by Tim Wilkinson.
Connect the servos to your arduino, pins 9 and 10 for pwm, and 5V/Gnd. You'll need to connect the receiver to Gnd and 5v, as well as RX (pin 0).
In the future I may migrate to the delfy22 iBus_Arduino library which could support telemetry. Additionally I'd like to have some of the other channels control some digital outputs etc.
