To set up a dual elevator servo mix with trim function on the JR X9303 2.4:

1. Use the 9303’s built-in dual elevator program. This activates the gear and elevator channels at the same time, ensuring perfect servo synchronization.

2. Connect one elevator servo to the Elevator channel and the second servo to the Gear channel.

3. Enable the dual elevator function in the transmitter. This avoids the delay seen in a regular mix (e.g., elevator to Aux. 3), ensuring both servos respond together.

4. Use Sub Trim to fine-tune each servo arm to 90° for proper alignment.

5. Use Travel Adjust to ensure both servos move the same amount in each direction.

This setup allows both servos to respond to trim inputs and stick movements equally.

AR7000 7-channel full-range receiver AR9000 9-channel full-range receiver Important: When using the X9303 2.4 with parkflyer receivers (the AR6000 and AR6100), it’s imperative that these receivers only be flown in parkflyer-type aircraft (small electric airplanes or mini and micro helicopters). Flying receivers designed for parkflyers in larger aircraft could cause loss of control.
