Control Direction Test
Properly bind your aircraft and transmitter before doing these tests. Verify the linkages
move freely. Switch ON the transmitter and connect the battery.
Use the transmitter to operate the aileron and elevator controls. View the aircraft from the rear when checking the
control directions.
Ailerons

aircraft to bank left in flight.
2. Move the aileron stick to the right. The right elevon should move up and the left elevon down, which will cause the
aircraft to bank right in flight.
Elevators
3. Pull the elevator stick back. The elevons should move up, which will cause the aircraft to pitch up in flight.
4. Push the elevator stick forward. The elevons should move down, which will cause the aircraft to pitch down in
flight.
Rudder/ Differential Thrust
