Checking the Rudder
Check the movement of the rudder using the transmitter.
When the left stick is moved left, the rudder should also
move left. This will cause the aircraft to turn left while on
the ground and to yaw left while in flight.
Section 14: Checking the Control Surface Movement
Check the movement of the rudder using the transmitter.
When the rudder/throttle stick (left side of the transmitter)
is moved right, the rudder should also move right. This
will cause the aircraft to turn right while on the ground
and to yaw right while in flight.
