Great Planes RV-4 Park Flyer Kit - GPMA0010 - Manual (Page 33)

6. Mark the location of the battery on the outside of
the fuselage.
❏
7. Use Great Planes Hook and Loop 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 fuselage 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 as we did in the photo.
Otherwise, you may damage the model while removing the
battery!
❏
8. Mount the receiver and speed control to one of the
fuse sides or to the fuse top deck with Velcro or double-
sided foam mounting tape. If the speed control has a switch,
install it on the fuselage side.
❏
9. 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 bottom
of the fuselage, guiding the antenna through, and taping it
to the rear of the fuselage 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.
❏
10. Recheck the C.G. to make certain the model
balances correctly. If the battery is held in place with Velcro,
you will be able to shift it slightly to fine tune the C.G.
❏
11. Check the lateral balance of the model. With the wing
level, carefully lift the model by the motor propeller shaft and the
fin. Do this several times. If one wing always drops when you lift
the model, that side is heavy. Balance the airplane by adding
weight to the other wing tip. An airplane that has been laterally
balanced will track better in loops and other maneuvers.
❏
1. For safety, remove the propeller from the motor. Move
the throttle stick to the off position, or towards you. Connect
a 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. If necessary,
remove the servo arms from the servos, and then remount
them so they are centered.
Warning: Whenever the model is not being flown or set
up, the battery should be disconnected.
