Great Planes Tutor Park Flyer Kit- GPMA0002 - Manual (Page 20)

3. With the model ready to fly and all parts installed
except for the battery, position the battery pack on top of the
wing as shown in the photo. Lift the model at the balance
point or place it on a Great Planes C.G. Machine. If the tail
drops, the model is “tail heavy”. If the nose drops, it is “nose
heavy”. Position the battery on top of the wing so the model
will balance. This is the location where the battery must be
mounted inside the fuselage to balance the model, thus
eliminating additional ballast (nose or tail weight). Because
weight is critical to the flight performance of Park Flyers, it is
best to balance the plane by mounting the battery in the
optimum location. Minor C.G. changes can be made by
changing the location of the receiver as well.
❏
4. Mark the location of the battery on the outside of the
fuselage.
❏
5. Use Great Planes Velcro ® (GPMQ4480, not included),
or another suitable method to mount the battery. Keep in
mind that the battery should be readily removable to allow it
to cool, and in case you have additional battery packs.
Note: If using Velcro to mount the battery, reinforce the fuse
bottom with two 3/4" [19mm] wide strips of leftover 1/16"
[1.6mm] balsa. Additionally, only a couple of 1/4" [6mm]
wide strips of Velcro are required to secure the battery-do
not use a whole sheet. Otherwise, you may damage the
model while removing the battery!
❏
6. Mount the battery. Mount the receiver to one of the
fuse sides or to the fuse bottom with Velcro or double-sided
foam mounting tape.
❏
7. Determine your method for extending the receiver
antenna and routing it through the fuselage. Something as
simple as drilling a 1/16" [1.6mm] hole through the top of the
fuselage, guiding the antenna through, and taping it to the
stab or fin is acceptable. Be certain there is no way that the
antenna can reach the propeller! Never coil-up the antenna
inside the fuselage, nor cut it. The antenna is tuned to a
certain length.
❏
8. Recheck the C.G. to make certain the model balances.
If the battery is held in place with Velcro, you will be able to
shift it slightly to fine tune the C.G.
❏
1. For safety, remove the propeller from the motor. Move
the throttle stick to the off position, or towards you. Connect
the charged battery to the speed control. Turn on the
transmitter, then follow the instructions that came with your
speed control to turn on the receiver.
❏
2. Center the trims on the transmitter. Operate the servos
by moving the control sticks. Check that the servos respond
in the correct direction as shown in the diagram. If
necessary, use the servo reversing function in your
transmitter to get the controls to respond correctly.
WARNING: Whenever the model is not being flown or setup,
the battery should be disconnected.
