

Check the engine Mount Bolts

Remove the spinner and propeller from the engine.

Remove the exhaust stacks from the fuselage, and

then remove the cowling from the fuselage. Remove

the muffler from the engine, and then use a Phillips

screwdriver to make sure the four bolts securing the

engine to the mount are tight.



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.
