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.
