vise that you make 2 triangular inlet
holes in the nose cone to provide
extra cooling of the motor & battery
pack. Don’t cut a cooling inlet hole in
the underside of the nose cone, as it
tends to ingest grass and dirt during
landing. If you fly in a much cooler
country than Thailand these holes
may be a little smaller than shown, or
possibly omitted altogether.
Cooling air flows under & above the
battery tray to provide the most effi-
cient cooling possible for the Lipos.
Do not use a spinner, as it may pre-
vent enough cooling air entering the
fuselage. Just use a simple prop-
adapter as shown here.
As a general rule, the Lipo batteries
should not get warmer then 55 de-
grees C, and the motor a maximum
of 70°. Most quality speed-controllers
will normally cut out if they get too
hot. If this happens in flight, and you
have enough height/speed, they will
usually work again after 10 - 15 sec-
onds of cooling, and this allows to
you make a circuit for landing. In this
case you know that you will need to
increase the cooling air inlet area be-
fore flying again.
Cockpit Canopy
Included in the kit is a very lightweight
fibreglass canopy, with the
foam/glass baseplate already in-
stalled. No clear cockpit canopy is
available for the Komet at this time.
The canopy is held in place with a
thin fibreglass, or plywood, strip glued
inside the back, which slides under-
neath the fuselage edge, and a hook
and rubber band at the front. Glue the
strip in place with thick CA, leaving
about 5mm projecting as shown.
Glue the milled 5mm balsa reinforce-
ments part onto the top of the foam
