R/C & Gear Installation
Finished in 5 - 7 hours
Everyone has their own favourite methods
when fitting the R/C and gear, but the
installation shown should be used as a
guide, and similar set-ups have worked
perfectly in all of our planes flown by C-
ARF factory staff, and many of our cus-
tomers.
C-ARF highly recommend that you install a
dual receiver battery system, with a high-
quality servo powerbus unit and dual
switches as shown, for the ultimate in safe-
ty and security. The full ‘PowerBox’ range
is all available from C-ARF as an option.
Visit our website for more details.
We recommend 2 Rx batteries of 5-cells,
between 1800 - 2400 mAH each, and if you have built the
SuperXtra using the DA-150 and the set-up shown in these
instructions you should find that one battery each side of
the fuel tank, on a foam rubber pad, secured to the carbon-
composite tank base with cable-ties, will give the correct
Centre of Gravity.
(Please double-check the manual for
your R/C system if the use of 5-cell NiCads is recommend-
ed, or not)
Please make sure that all the Nicad batteries are fixed very
securely in the plane, as the forces on these heavy items
during high ‘G’ manoeuvres is extremely high.
When fitting the batteries, make sure that you will still have
easy access to the plastic nuts that go on the front wing
mounting dowels during assembly of the plane.
Dual NiCad and Powerbox installation
The PowerBox 40/24 power control unit is designed espe-
cially for large models and provides dual battery inputs with
hi-amp connectors, multiple outputs for 6 channels/24 ser-
vos (no ‘Y’ leads needed), automatic voltage regulation and
stability, built-in servo amplifiers for those long servo
cables, as well as dual visual LED battery displays. It
comes complete with hi-current connectors and is fitted
with anti-suppression chokes on all channels.
The Powerbox is screwed to the angled plate, and the
receiver is mounted on the vertical bulkhead behind it, as
shown, on foam pad, with 2 rubber bands. on a scrap 3mm
plywood stick that is glued to the front of the bulkhead This
makes for a very neat installation, with no unnecessary
extensions and loose cables in the plane. With the R/C

fixed either side of the tank base
