This is David's red night fly, a Goldberg Eagle II. David has logged over 100 hours of
flight time on this aircraft, mostly at night! The engine is an O.S. .20 with a Davis
Diesel conversion head. The average flight time for this aircraft with an 10-oz. tank
used to be over an hour. However, with a recent (and extremely simple) modification to the
engine, his flight times now average about 2 hours and 15 minutes on a cool winter day.
Summer flights will be predictably longer, since the engine will run more efficiently in
the heat.

Here is David's green night fly Eagle II. This plane is powered by an O.S. .26 4-stroke
engine that David, himself, converted to run on diesel. The engine is extremely efficient
and provides approximately 2 hours and 15 minutes of flight time on an 8-oz. tank. Both
this plane and the red night fly, above, are equipped with an electrical power generator,
designed and built by David, to power the receiver and lights.

This is one of David's newest creations - an aerobatic night flyer. It is a Great Planes
Extra Special. The aircraft possesses a unique bi-color lighting system, with red on one
side, and gold on the other. As I understand it, the colors can be switched from the
transmitter. This plane is powered by an O.S. .40 FP (converted to diesel of course) and
carries a prototype for a new on-board alternator (patent pending).

This is the Bird of Time - the sailplane that was converted for
powered flight for an attempt to set a new distance record. It was powered by an O.S.
.26 diesel 4-stroke engine that is now in the green Eagle II. The Bird was lost in an
unfortunate mishap during the final stages of testing prior to the distance record attempt.
However, it has since been rebuilt for some serious recreational (i.e. stress-free) flying.

David's newest and wildest creation is the Flyin' King, a.k.a. The Chameleon. It is
currently under construction, but nearing completion.
Many new innovations are included in this aircraft, including a new and highly improved
multi-phase alternator design (patent pending) to provide power to the on-board receiver,
multi-color lighting system, video camera and video transmitter. A unique switching system
allows the pilot to select several different mix-and-match lighting patterns among the
available colors (red, orange, gold, blue, green & infra-red). The aircraft and alternator
will be powered by an O.S. 60 FP with a Davis Diesel conversion head.

Below, is a couple of images of the Chameleon showing only two of the many, many possible
color combinations.
