Adjusting the Steering Trim
When adjusting the steering trim, do not use the trim on
the transmitter. The rudder trim on the transmitter is used
to trim the rudder while the aircraft is in flight. If you find
your model does not track straight during taxi, loosen
the screw and adjust the position of the nose wheel.
Remember to tighten the screw as soon as you have
changed the position of the nose wheel.
