Control Surface Centering
Before your first flights, or in the event of a crash, check
to make sure the flight control surfaces are centered. It is
much better to do this mechanically due to the mechanical
limits of linear servos.
1. Make sure the transmitter trims are centered, and
sub-trims are set to 0.
2. Check to see if any of the flight control surfaces are
not centered.
Control Direction Test
CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.
Test the controls prior to the first flight to ensure none
of the servos, linkages or parts were damaged during
shipping and handling and the controls function in the
correct directions.
Move the rudder stick to the right. The rudder should
move to the right. This will cause the aircraft to yaw and
bank to the right in flight.
Move the rudder stick to the left. The rudder should move
to the left. This will cause the aircraft to yaw and bank to
the left in flight.
Pull the elevator stick backward. The elevator should
move up. This will cause the nose of the aircraft to pitch
up in flight.
Push the elevator stick forward. The elevator should move
down. This will cause the nose of the aircraft to pitch
down in flight.
If at any time during the test the controls respond in the
opposite direction of operation of the flight controls, follow
your transmitter's instructions to reverse the flight controls.
3. If the surface is not centered, use a pair of pliers and
carefully lengthen or shorten the pushrod by adjusting
the U-shape in the pushrod.
