I just want to share the setup for my Skymaster-Xtreme F-18C Hornet.
I'm using ailvator mode on Futaba 12FGA 2.4GHz FASST transmitter, it comes with 14-channel receiver and here’s the following setup and function:
Ch1: Elevator 1 (port side), 45mm up and down with -50%expo, aileron 35%
Ch2: Elevator 2 (starboard side), 45mm up and down with -50%expo, aileron 35%
Ch3: Rudder, approx 60% drive and -40% expo
Ch4: Aileron 1, 15mm throw with -40expo and 30% flaps mix on landing
Ch5: Aileron 2, 15mm throw with -40expo and 30% flaps mix on landing
Ch6: Throttle,
Ch7: Flaps 1, 25mm for takeoff and 50mm for landing
Ch8: Flaps 2, 25mm for takeoff and 50mm for landing
Ch9: Landing gear,
Ch10: Spoiler,
Ch11: Wheel brakes,
Ch12: 3-position switch engine aux ( shutdown, standby & smoke option),
Ch13: Rx Voltage monitor (no Tx control) and
Ch14: Rx Backup power supply
All surface control has servo reduced speed setup to prevent it from stress during sudden stick operation.
I’m also planning to put aileron on the flaps only for landing mode condition so I would have high control output on almost stall speed on landing.

Happy flying,
John
