6. Installing the receiver:
The next step is to connect the servo plugs to the receiver.
This is the key to the numbered plugs:
1 Left aileron
2 Elevator
3 Rudder
4 Throttle
5 Right aileron
Secure the receiver below the instrument panel using small
pieces of the hook-and-loop tape 27 / 28.
7. Checking the CG:
Place the fl ight battery in the battery tray, and adjust its
position until the model balances at the 90 mm C.G. mark
(measured from the wing leading edge adjacent to the
fuselage). Fix the battery in place with the hook-and-loop
tape supplied.
We recommend applying a few drops of Zacki to the adhe-
sive face of the hook-and-loop tape to stick it securely to
the bottom of the fuselage.
