Replacing the Propeller
The propeller is threaded onto the shaft of the gearbox.
1. To remove the propeller, use needle-nose pliers or
hemostats to grip the prop shaft.
2. Spin the propeller counterclockwise (if viewed from
the front) to remove the old propeller.
3. Thread the new 100mm x 60mm prop and spinner clock-
wise onto the gearbox shaft.
You may find that you need to replace the prop shaft in the
gearbox should it become damaged. To replace the prop shaft:
1. To remove prop shaft, open the fuselage by cutting
through the decal on one side of the fuselage. Remove the
plastic dummy engine by gently pulling off the fuselage.
2. Gently grasp the white nylon nut located at the back of the
prop shaft to prevent it from turning.
3. While holding the nylon nut, rotate the spur gear in a
clockwise direction. The prop shaft will thread out of
the nut.
