COMPANY PROFILE:

Alternative Power manufactures a chain-drive, cast-aluminum PSRU for the
experimental homebuilt aviation and airboat world. We have developed PSRU
for airplanes, airboat and the cheetah 350 helicopter are cast from 356
aluminum and is available in two gear ratios for the Chevrolet V8 engine.

Because of the unique power requirements of the helicopter rotor blade
system, the gear ratios are more limited. The new airplane PSRU
under development and soon to be tested is the constant speed propeller system.

The price will start at $3600 depending on options. We will be at the EAA
Convention in Oshkosh in 2000. Be sure to look for us in the experimental
homebuilt helicopter show area!

AIRPLANE:

Alternative Power has the airplane PSRU currently flying in many different
aircraft. This unit weights a mere 60# complete, depending on the version
requested. This one-piece unit is made in our own foundry.

We have done all the flight testing in a Cessna 172 that has logged over
350 hours total flight time using our Chevrolet 350 V8 aircraft.

The latest innovation incorporated into the manufacture is the
Sprag clutch system. We will show this at the EAA Convention this year.

This is currently available as a special order option. This option will be
showing up in the airboat industry very soon.

HELICOPTER:

Alternative Power's experimental Cheetah 350 helicopter is the most
sophisticated of all our units. The 4-bladed rotor system was
developed with #6061T6 aluminum. The aluminum 6061T6 swash plate and rotor
head were developed to fit a 3" steel rotor mast. Thetotal weight of the transmission
(PSRU) is approximately 100 pounds. ThisChevrolet V8 aircraft will develop 350 horsepower.

Our prototype homebuilt Cheetah 350 tandem helicopter will be flight tested
soon. Look for us at the EAA Convention in Oshkosh!

FUTURE INNOVATIONS:

Alternative Power is currently working on a PSRU for the Subaru and v8 aircraft that
will have counter-rotating propellers! This unique PSRU should develop significantly
more efficiency (up to 25% more) using the same horsepower . an ideal homebuilt project .
