At the time this was the worlds only Subaru on an RV9A using a hydraulic constant speed prop. This prototype unit has all of the same features of the original Geared Drives PSRU including its own oil reservoir, oil pump and filtration system, drive port for hydraulic prop governor, and flywheel and centrifugal clutch assembly. This airplane with the P2 prototype Geared Drives PSRU can be seen at Sun n Fun Air Show, Lakeland, FL, April 21-26, 2009. Look for the Geared Drives booth N52 for directions the aircraft location.
Larry Ketterlings P-51 Engine
Geared Drives FWF engine package for P-51 at idle and run up very
conservatively since we were testing ignition only and there was no prop
installed. Note how smoothly the engine transitions from low RPM to higher
RPM. Nice rumbling sound through the short custom Exhaust, volume increased via the collector with
baffling within to provide back pressure and guard against shock cooling

Geared Drives 200Z PSRU for Subaru
Test running the Geared Drives PSRU for Subaru on our test engine mule,
Frankenstein. Running for eight hours this day, the oil temperature is
cool enough you can wrap your hand around the oil filter and it is barely
over body temperature. Swinging a 72" Hartzell two blade hydraulic prop at
full pitch, the gearbox is performing perfectly and ready to take its place
as a retrofit to Eggenfellners gearbox. Torsional harmonics are resolved
via the Geared Drives centrifugal clutch system.
RV 10 Run up with Geared Drives FWF engine package
Note: battery was a little low...Bill Gipson of Conroe, TX runs his engine
up, cycles the prop, and shuts it down for viewers. This was immediately
after taxiing around the airport and filling up with fuel. This airplane
runs cool, even on taxi. Note that the centrifugal clutch starts the prop
just after the engine starts and also that the prop spins to a stop upon
Truyeart LS1 Engine for his RV-10 Starts for the first time!
Another Geared Drives LS1 engine package for RV-10 roars to life for the
very first time! The engine starts easily and runs at low RPM since it is
not good for it to run without the load of a propeller on it. We run it
long enough to test the systems, check for leaks, test the PSRU etc. At the
very end of the video you can see the breather on the PSRU kick over the
little bit of overage of oil as it seeks its natural level in the gearbox.
This is normal for a first run up.
Glasair 1RG Fly By 260 MPH - Subaru EG33 Motor

Glasair Subaru First Test Start

1/2 years. I designed this Subaru engine installation. This is the first
test start of the engine. Visit GlasairProject.com
Aircraft Emergency And Landing in a Glasair - the impossible turn ???
My Glasair engine is a Subaru SVX EG-33. Six bearings in the planetary
speed reduction unit failed during departure. I declared an in-flight
emergency and immediately returned for landing. Total flight time was 63
I failed to plug the camera mike in so you don't hear the engine monitor
blaring out alarms or chatter between other pilots and myself.
Departure was made with 10 degrees of flaps and remained there until
landing with 25 degrees. The buzzer during much of the flight is the "gear
up" with "flaps extended" warning horn ... the stall horn never sounded.
Speed did drop but the flight never reached critically low speed. Power
was intentionally reduced to keep gearbox temps down. I fly patrol flights
at 500 ft or less, often 6 to 7 hrs a day. So I do have low level
maneuvering experience. Some may call this the impossible turn but power
was available during the entire flight.
