Our Test Aircraft
Mike Duggan's beautiful RV-8A (aka "Woodstock")
Now in the shop is a very nice RV-8A owned by Mike Duggan. This great looking RV named "Woodstock"
will receive an electrical bus transformation with a
Bus Manager to provide a protected essential
bus as well as the full EFII engine management treatment. Instant starting (hot or cold) should be a nice
addition to Woodstock's high compression
IO-360 angle valve motor. The extra 10% horesepower increase from the EFII will be impressive as well!
This thing should really "fly" when it's done! Watch for more detailed info
on the Customer Projects page.
The "Scudbuster" Clip Wing Taylorcraft
The Scudbuster is a highly modified clip wing aircraft that was built in the early 1990's
as an airshow stunt plane. Though derived from a Taylorcraft, the Scudbuster has been highly
modified including the addition of a 150hp Lycoming O-320 engine. "Scuddy", as we tend to refer
to it is a single seat acrobat with nine feet clipped from the wings. Scuddy has been our
test bed aircraft for the development of the Lycoming EFII kit. Scuddy has been flying and
showing off the power gains from it's new EFII system. We haven't dynoed the engine, but based
upon aircraft performance, we believe there has been about a 10% increase in horsepower with the
EFII system. The Scudbuster lifts its tail in unison with the application of throttle. Scuddy
happily climbs out at 1500fpm at 100mph and quickly hits 140mph after leveling out. Starting the engine
is as simple as turning on the bus master and holding the start button for about one second.
The O-320 is already breathing strongly on its own after that. Run-up consists of raising the rpm to
get some heat in the oil, and taking a look at oil pressure and fuel pressure - and that's about it!
The Subaru RV-7
The EFII system had it's beginnings in the development of our H6 Subaru powered RV-7.
This plane was used to develop and test fly the first generation electrical bus system,
fuel system, and electronic engine management system. The RV-7 was flown for more
than 400 hours including three visits to the Oshkosh airshow. The engine management
systems performed flawlessly throughout the operation of this aircraft. This aircraft
is now living back at our shop and receiving the full EFII treatment on a fresh Lyc O-360.
