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 130mm x 70mm prop and spinner clockwise
onto the gearbox shaft.
Replacing the Prop Shaft
You may need to replace the prop shaft in the gearbox should it
become damaged. To replace the prop shaft:
1. Open the fuselage by cutting through the decal on one side of
the fuselage, and on the top turtle deck.
Note: Do not pull off the clear tape; it will remove the color
from the airframe.
2. Gently grasp the white nylon nut located at the back of the
prop shaft, use needle-nose pliers or hemostats.
3. While holding the nylon nut, rotate the spur gear clockwise.
The prop shaft will thread out of the nut.
4. Gently pull on the spur gear and the prop shaft will slide out of
the gearbox.
5. Thread the 130mm x 70mm prop and spinner onto the
new prop shaft by holding the spur gear and turning the
prop clockwise.
6. Slide the new prop shaft back into the gearbox.
7. Place the nylon nut on the back of the prop shaft. Spin the
prop and spur gear counterclockwise. The nylon nut will
thread onto the prop shaft.
8. While holding the nylon nut in place, gently turn the spur gear
counterclockwise to ensure the nut is snug.
9. Tape the fuselage back together with clear tape.
