a small hole through the right fuselage side, just below the wing
saddle and just in front of the fuselage former separating the servo
and receiver compartments. Then, pull the antenna through this
hole and extend it back to the tail end of the fuselage.
❑ 26) To hold the antenna at the rear of the fuselage, use a pair
of needle nose pliers to make a small wire hook with a loop at one
end out of a straight pin (not supplied). Glue the hook to the rear
of the fuselage, beneath the stabilizer, using a little thick CA. Then,
use a small rubber band (not supplied) to cinch the antenna to the
wire hook.
❑ 27) Plug the rudder and servo leads into the appropriate
receptacles in your receiver. Also, plug the aileron Y-harness into
the aileron receptacle in the receiver.
ELECTRONIC SPEED CONTROL (ESC) INSTALLATION:
❑ 28) The provided RC System 18 amp brushless ESC will now
be installed into the plywood box immediately behind the
firewall/motor mount, secured with a piece of Velcro
® tape. But
before the ESC is installed, the positive (red) and negative (black)
battery wires must first be prepared with a connector (not
included). Good connectors, typically, require soldering of these
wires and this requires the use of a soldering iron and flux. For our
ESC and battery connectors, we chose to use a Kavan #6321 K-2
connector set. These great little connectors are small, lightweight,
and self-polarizing.
a) Solder a battery connector to the two black (negative) and
red (positive) wires on the ESC. Solder the corresponding
connector to your flight pack battery.
b) Note that the ESC is installed into the plywood box with the
flight battery connector routed into the battery compartment
and the receiver connector routed into the fuselage where
the receiver is in place. The three forward motor wires are
located toward the front of the fuselage as shown. Attach
Velcro
® strips to the bottom of the ESC and to the bottom of
the ESC tray and press the ESC in place. NOTE: DO NOT
pad or pack the ESC in foam or plastic. It must be left fully
exposed, allowing it to stay cool.
c) Connect the ESC receiver connector into the appropriate
throttle receptacle in the receiver.
MOUNTING THE MOTOR:
❑ 29) The brushless motor is now mounted to the firewall/motor
mount at the front of the fuselage.
a) Use a 1.5 mm hex or ball-driver wrench to remove the rear
aluminum motor mount from the motor shaft. Use the hex
wrench to loosen the two grub screws just enough to allow
the motor to be removed.
