❏ 2. Securely mount the receiver and battery using
1/4" or 1/2" [6 or 13mm] R/C foam rubber to protect them from vibration. The included Velcro strips may be used to secure them where preferred. On the prototype test models the battery was mounted to the top of the wing bolt plate in the fuselage and the receiver was mounted to the forward servo tray. If preferred, the battery location could be determined while balancing the model, thus reducing or eliminating any additional ballast required to get the model to balance.
❏ 3. Connect the battery, switch(es) and servos to
the receiver. Use servo extensions or Y-connectors where necessary (on the model shown in the photo, 6" or 8" [150 or 200mm] servo extensions were required for each elevator servo, and for the battery and the aileron plug in the receiver.
❏ 4. Make a
strain relief
for the receiver antenna
from a leftover servo arm. Install the strain relief near
the end of the antenna where it enters the receiver. Drill 3/32" holes through a few of the formers to guide the receiver antenna away from the servos and wires. Guide the antenna through a hole in the fuselage insulated with a piece of leftover air line or fuel tubing. Connect the end of the antenna to a pin stuck into the fin via a rubber band and a
hook
made
from another leftover servo arm.
Balance the Model (C.G.) The model should be in ready-to-fly condition with all of the systems in place including the landing gear, engine, propeller, spinner, etc. It is advisable to have two people to balance the model—one to hold the model (or place it on the balance stand) and one to view it from the side to see if the stabilizer is level.
❏ 1. If using a Great Planes C.G. Machine to balance
the model, set the rulers to 4-9/16" [116mm] and adjust the bases so the upright rods are spaced approximately 22-1/2" [570mm] apart (to support the wing at the “break” in the leading edge as shown in the sketch). If not using a C.G. machine, accurately mark the C.G. on the top of both sides of the wing 4-9/16" [116mm] from the “break” in the leading edge with a fine-point felt-tip pen. Connect the marks with a strip of 1/8" [3mm] (or narrower) tape. (You will be able to feel the tape line when lifting the model upside-down with your fingers.)
More than any other factor, the C.G. (balance
point) can have the greatest effect on how a model flies and may determine whether or not your first flight will be successful. If you value this model and wish to enjoy it for many flights, DO NOT OVERLOOK THIS IMPORTANT PROCEDURE. A model that is not properly balanced will be unstable and possibly unflyable.
