Many members of Chapter 36 are avid builders and restorers. There talents and expertise is the hallmark or our chapter.
The photos to the right and below, show the various stages in the building of an "L1.9 Aardvark" .
Joe Boyle is the owner and master builder of this single place aircraft, constructed of wood, foam and fiberglass.
The Aardvark look is due to the planetary gear reduction unit on the front of the engine to slow crankshaft RPM down to Prop RPM, a reduction of about 3:1.
It is17'9" long and has a 30' wingspan.
The wing has a 55" cord.
Empty weight should be about 400 lbs.
Gross weight about 600 lbs.
Cruise should be about 65 mph, stall about 25 mph and vne about 90 mph.
It is powered by a 430cc twin carb Cuyuna 2 cylinder, 2 cycle engine producing approximately 45 HP.
Red letter day......right.
Wings attached for the first time for alignment and match drilling of the attach brackets, measurement of the lift struts and drag struts, etc.
Joe is re-designing the ailerons from full span to tip and designing the torque tube actuators and mounting hardware, and still has 1 aileron to build and then all the big parts will be completed.
Joe says "It's hard to believe the first pieces were built in 1988. It just might fly yet".
Knowing Joe, it will fly, and very well.

The Aardvark is all in one piece in Don Myers' hangar.
He and I completed assembly yesterday and I did some engine and Taxi tests.
It actually moved under it's own power.
It may even fly some day.

The Aardvark, N68902, got her airworthiness certificate and on April 7th, her first 2 test flights were completed at W35
The re-engine project from the 430 Cuyuna to a Rotax 582, C gearbox and GSC 66" prop is complete.
I have 10 hours on it now and have most of the bugs out.
I flew 1 short cross country to Green landings and back to W35.
On the leg down, I flew as wingman to a Bald Eagle over the Potomac river near Big Pool.
I'm considering adding to the ailerons for more low speed roll control.
Stalls straight ahead at about 35mph, 75% cruise, (4800 rpm) is about 65mph indicated, climbs at about 800fpm at 60mph, full power straight and level, (6500 rpm) is about 84mph indicated with 15 degrees of pitch on the prop.
It will go faster but I don't want to. I prefer to keep the wings on it.
Since those pictures were published, the fuselage and tail feathers have been completed, the windows and window trim have been completed and installed.
The cabin roof and greenhouse, also, have been completed, and the fuselage and tail feather surfaces sanded and filled.
The fuselage and tail feathers are now ready for paint.
The interior has been completed and painted, the carpet is installed and the seat upholstered and installed.
The seatbelts and shoulder harness are also installed.
Joe is now working on the wings as weather permits.

I have the tail feathers ready to prime.........
I should spray them tomorrow morning and install them Tuesday evening....
The white is primer.
I'm leaving it all in primer to get it inspected and make the test flights in case I have to change something.
I'll paint it after I get it licensed and the test hours flown off.
I didn't quite make my goal of flying it before my 65th birthday but it should fly this summer.
