R/C & Gear Installation
Everyone has their own favourite methods for fitting the R/C and gear, but the installation tech-
niques shown here can be used as a guide and they have worked perfectly in all of our planes
flown by C-ARF factory staff, and many of our customers. The advice below applies to whatev-
er engine type you chose to fit; gas, glow or electric.
With a plane of this size it is important to keep everything lightweight to ensure the best perform-
ance and flying characteristics, and the Hacker 50 electric power version shown only weighs
5.9kg ready to fly. The DA-50 powered version is quite a bit heavier at about 7kg, dry. Of course,
the final weight of your model will depend a lot on the power plant used, and if you decide to add
any trim or paint to the model.
Receiver and Antenna
The receiver can be fitted anywhere you like,
but the 2 choices shown minimise the number
of extension leads required. Please protect it
from vibration and shocks (even if you chose to
use electric power) by mounting it on some
foam rubber, and don’t forget to secure the
receiver crystal with a piece of clear tape.
With electric power it can be installed on the
side of the fuselage as shown, or if using a
gas/glow motor you can use the mount provid-
ed on the vertical back face of the fuel tank
base. Run the antenna wire along the side of the
fuselage in the cockpit area, taped in place, and
then vertically through the top of the fuselage (in
a piece of silicone tube) behind the cockpit and
back towards the vertical stab (see photo). Keep
it as far away as possible from the cables for the
elevator servos and the closed-loop rudder
wires.
Composite-ARF strongly advise you to keep all
the cables between the motor ignition battery,
ignition switch, gas-engine ignition unit, or elec-
tric motor and speed controller, as far away as
possible from the Receiver and Antenna.
Receiver Batteries
As this model only has 5 or 6 servos, even if
they are all digital types as we have used here,
a single receiver battery pack of 5 cells x 1400
mAH is normally quite sufficient. Wrap the
Nicads in foam, to protect the soldered joints
from vibrations and shocks. Of course, if you
need more weight in the nose of the ‘plane to
achieve the correct Centre of gravity, it is better
to install a larger Nicad - rather then add lead.
