Te B.O.T. Speed Cruiser with D-Motor will be used to train disabled military veterans.
yet produces an attractive finished aircraft. The new
Belite UltraCub has a new aluminum fuselage and
was powered (very successfully) with a Scott Casler
½ VW engine. The airplane is covered with conventional Dacron and Oracal 951 film. The film is similar
to that used for vinyl adhesive lettering such as the N
numbers on airplanes and decorations on racing cars.
The high-tech PVC film comes in rolls in more than 90
colors and can conform to compound surfaces. The
procedure is to first cover the airframe with fabric
using the Stewart system, shrink the fabric, and then
overlay the peel-and-stick colored film directly on the
fabric. It's fast and easy and there is no need for any
spraying or painting. The weight of the finished product is equal to a very light spray-painted covering, yet
it gives a high-gloss finish. The film is not fuel proof,
so extra protection is needed near the fuel tank where
spills could occur. See more pictures of the finished
product on the Belite Flickr page.
mounted valves reduce the parts count and the cost.
The result is a narrow profile and simplified installation. Designers have taken an old concept and updated
it with electronic ignition and fuel injection. The all-up,
ready-to-run weight is 138 pounds including exhaust,
and the cost is less than a Rotax 912 series engine
and much less than the fuel-injected Rotax. The demo
engine on the test stand started easily and ran quietly
and very smoothly right up to cruise rpm. Redline rpm
