Hello all. I have the Phantom 2 with Futaba FG8 and the R6208SB receiver. I'm looking to connect a set of RETRAX retractable landing gear. The twin servos connect in a Y cable that attaches to one channel on the receiver. Can't figure out the best channel (considering failsafe having landing gear come down) to use and how to program the transmitter. Any help or guidance will be greatly appreciated.
