7. Servo arm position should be as shown.
Note: It may be necessary to adjust the clevis to
center the rudder once the pushrod is attached to the
servo. It is advisable to attach a 4-inch (100mm) piece
of clear tape on either side of the rudder hinge. We
recommend 3M Blenderm tape or hinge tape.
Hand Launching the P-51 Mustang
Mode Change Flight Control System
Important: Initial flights should always be done
with the airplane in Low Rate (Mode A). In this
mode, there is some limitation to the travel of
the control surfaces, helping to prevent you from
overcontrol. After you have had several safe
flights in Mode A, you can move on to Mode B,
which will no longer limit the travel of the control
surfaces.
Note: It is possible to change flight modes while the
plane is in flight. However, it is important that you
have enough altitude while in flight before changing
the flight mode.
Your P-51D Mustang comes with the ability to change
flight modes as you gain more experience and become
more familiar with it. There are two modes, selectable
from the transmitter, from which you can choose.
Mode A (Low Rate) - Mode A is recommended for all
first flights. The travel of both ailerons, as well as the
elevator, will be limited in this mode, allowing you to
become more familiar with your plane. The switch on top
of the transmitter will be back when you are in this mode.
Mode B (High Rate) - Mode B does not limit your
control surface travel, allowing more aggressive flying
and aerobatics. However, your P-51D Mustang will also
be more prone to crashes due to over-control if you are
not careful. The switch on the transmitter will be toward
the pilot when in this mode.
Low Rate = A
High Rate = B
First Flights
5. Attach the clevis to the control horn.
6. Turn on the airplane and center the rudder servo.
Slide the servo horn onto the “Z” bend of the
pushrod in the outermost hole and attach the
servo horn to the servo making sure the servo
horn is at 90 degrees to the pushrod.
Your P-51D Mustang will need to be hand launched. To
do this, follow these instructions:
1. Make certain that the aircraft battery is fully
charged.
2. Turn on the transmitter, making certain you are in
Mode A (Low Rate).
3. Insert the battery into the fuselage and plug the
battery lead into the lead coming from the
fuselage. Secure the battery with the hook and
loop straps.
4. Hold the airplane with your hand behind the wing
gripping the fuselage.
5. While holding the transmitter in one hand, push
throttle slider to full on (up) with thumb.
6. Take a couple of steps and FIRMLY launch directly
into the wind while keeping the wings level. Do not
throw it up or down. Point it level (parallel) with the
ground when launching. THROW IT HARD until you
become accustom to the amount of force it takes
to launch the plane.
7. Keep steering into the wind and hold at full throttle
in a slight climb until you have reached an altitude
of at least 50 to 70 feet (15 to 21 meters).
8. When you have reached this altitude, it is safe to
steer in the desired direction, as well as adjust the
throttle input, to help control altitude and speed.
Note: If airplane is thrown too lightly it is possible that
the airplane will not have enough airspeed to fly away
and control authority will be reduced the slower it is
thrown. The proper throw is similar to a javelin throw.
