Dave has
recently completed structural modifications to the wing of the craft,
including a metal skin, and "a rear spar torque box" which have added
addition strength, and the plane will shortly be stress tested and
analyzed by a university. The Cumulus features a welded steel fuselage
with a main boom running to the tail assembly. The wings plug and unplug
from the fuselage, for ease of transport and storage, with all of the
control systems automatically hooking up as you insert the wing.
The Cumulus will be offered as a kit taking between 150 and 200 hours
to build, with first deliveries available in August of 2003. At that time
it is expected the factory will be able to produce 2 kits per month.
The craft is powered by a 447 Rotax engine, takes off in 150 feet,
climbs out at 800 feet per minute, has a 20:1 glide ratio and a 90
ft per minute sink rate, and will cruise along under power at 65 mph.
A canopy to enclose the pilot area is currently under development.
