Construction:
Fuselage is a simple box structure. Balsa sides
and ply formers reinforced with glass cloth inside and out where
required.
Motor is soft mounted with rubber machine mounts.
All control systems are mounted behind the wing trailing edge,
this leaves room for the payload and motor battery to placed to
obtain the correct CG.
Wings are white styrene foam covered with 2 layers
of 2 & 3 ounce glass cloth. Wing tubes for joiner rod are
carbon fibre, the wing joining rod is also carbon fibre. Elevon
servos are mounted in the wing.

Plank Genesis
The plank aircraft have their genesis with an EMX07
wing cut by Ray circa 2000 at John Bird's instigation which lanquished
for a few years. It was finally assembled into our first prototype
plank (Cornflake video)
in mid-2002 by Greg Egan and is still intact. A second prototype
also by Greg (Weetie video)
with an MH60 was constructed one year later and is also still
intact. The designs are quite unusual for planks in that they
have distinctive long tail boom yielding excellent low
speed stability. The stall behaviour and general robustness of
planks when crashed into cargo nets, or just generally into the
scenery, is self evident.
