Replacing the Propeller
You may need to replace the propeller in the event of a crash.
If you have access to hemostats, grip the prop shaft
between the spinner and fuselage front and turn propeller
counterclockwise to remove propeller. If you don’t have
hemostats, continue below.
1. Have an adult carefully use a hobby knife and cut through
the clear tape on the side of the fuselage as well as across
the top seem of fuselage. See Step 1 of Replacing the Prop
Shaft.
2. Carefully remove fuselage top and side to gain access to
the inside.
3. Grab the spur gear (as shown) and turn propeller
counterclockwise until it releases from the prop shaft.
4. Thread the new 130mm x 70mm prop and spinner
clock wise onto the gearbox shaft.
5. Carefully place fuselage parts back and re-tape with
clear tape.
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. To remove prop shaft, open the fuselage by cutting through
the clear tape on one side of the fuselage. Also cut the tape
across the fuselage in front of the rudder.
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.
4. Gently pull on the spur gear and the prop shaft will slide out
of the gearbox. You may need to cut away a small portion
of foam to allow the spur gear to slide forward out of the
gearbox.
5. Remove the propeller from the old prop shaft, then
thread the 130mm x 70mm prop and spinner on to the
new prop shaft by holding the spur gear and turning the
prop clockwise.
6. Slide the new prop shaft back into the gearbox.
