Replacing the Propeller
Replacing the Prop Shaft
When you are ready for your first flight, you will want to select a relatively
open area, the size of a basketball court or larger, that is free of people
and obstructions with calm wind (if flown outdoors). Once you have properly
trimmed your airplane and become familiar with its handling and capabilities,
you will be able to fly in other smaller, less open areas.
Choosing a Flying Area
Flying the P-51D Mustang
Having followed the proper receiver initialization and arming procedures,
confirmed proper control of the servos and motor, and found a suitable flying
area, your P-51D Mustang is ready for flight. Start first flight using the low
rate set tings to become familiar with the flying characteristics before
increasing the throw of the control surfaces.
Place the P-51D Mustang in position for takeoff (facing into the wind if flying
outdoors). Gradually increase the throttle to ¾ to full, and steer with the
rudder. Pull back gently with the elevator and climb to check trim. Once
the plane is trimmed out, you can begin exploring the flight envelope of
the Mustang.
Note: Due to the large propeller on the Mustang, it is possible to hit the
prop on the ground while landing. Make sure to flare when landing
and try to land as smoothly as possible to minimize hitting the prop.
While this does not damage the airplane it is possible to wear down
the tips of the propeller if flying from an abrasive surface such as
concrete or asphalt.
• IN THE UNFORTUNATE EVENT OF A CRASH OR PROPELLER STRIKE, NO
MATTER HOW MINOR OR MAJOR, YOU MUST LOWER THE THROTTLE
STICK AND TRIM TO THEIR LOWEST POSSIBLE POSITIONS AS QUICKLY
AS POSSIBLE TO PREVENT DAMAGE TO THE ESC OF THE RECEIVER
UNIT.
Failure to lower the throttle stick and trim to the lowest possible
positions in the event of a crash could result in damage to the ESC in
the receiver unit, which may require replacement of the receiver unit.
Note: Crash damage is not covered under warranty.
The propeller is threaded onto the shaft of the gearbox.
1. To remove propeller, open the
fuselage by cutting through the
decal on one side of the fuselage.
2. Hold the spur gear with your
finger and spin the propeller off
the shaft.
3. Thread new 130mm x 70mm
prop and spinner onto the
gearbox shaft and tape the
fuslage back together with clear tape.
You may find that you need to replace the prop shaft in the gearbox
should it become damaged. To replace the prop shaft:
1. Gently grasp the white nylon nut located at the back of the prop shaft
to prevent it from turning.
2. While holding the nylon nut, rotate the spur gear in a clockwise
direction. The prop shaft will thread out of the nut.
3. Gently pull on the spur gear and prop shaft will slide out of the
gear box.
4. Thread the 130mm x 70mm prop and spinner on to the new prop shaft
by holding the spur gear and turning the prop in a clockwise direction.
5. Slide the new prop shaft back into the gear box.
6. Place the nylon nut on the back of the prop shaft. Spin the prop and
spur gear in a counter-clockwise direction. The nylon nut will thread onto
the prop shaft.
7. While holding the nylon nut in place, gently turn the spur gear
counterclockwise to ensure the nut is snug.
