need to be about 25mm (1”) diameter for the motors mentioned above.
We suggest that you tack glue the mount into the cone with 1 or 2 very small drops of CA, and then
temporarily tape the nose cone on the fuselage to confirm that it has the required side-thrust. No
down thrust is needed. Mark the position of the nose cone on the fuselage now, so that you glue
it back in the same position later, to
set the same thrust-line. When satis-
fied, remove the motor, and then glue
the motor mounting ring permanently
into the nose cone using a slow
(24hr) epoxy and micro-balloon mix-
ture. Finally glue the nose onto the
flange on the front of the fuselage,
using a little 30 minute epoxy.
Battery Tray
All the parts are supplied for the
balsa/fibreglass composite battery
and R/C tray, which is easily remov-
able for maintenance. It sits in the
cut-outs in the 3 foam bulkheads, and
is held into the fuselage by the front
anti-rotation dowels (which are glued
into the wings), and the front wing
joining rod.
If using the motor and battery packs
recommended, you will need to posi-
tion the middle of the battery approx.
over the front bulkhead (centred on
the front anti-rotation dowels) to
achieve the correct Centre of Gravity.
The battery tray is carefully designed
to allow cooling air to circulate both
under and above the battery, which is
suspended in the hole in the tray on
the velcro straps. Adjust the size of
the milled hole (35 x 110mm) to suit
your Lipo flight battery, if necessary.
The battery should be a loose fit in
the hole.
The design also allows you to move
the battery forward or backwards
about 25mm (1”) after assembly, to fi-
nally set the exact CG - and then you
can glue in some small balsa blocks
as ‘stops’ to retain it.
