As we are on the subject of the .3  rotary engine..... I can't help but
wonder what happened to the Suzuki 500 CC RE5 motorcycle..... It came out
around '76 and was on the market for a couple of years and vanished.......
Was this a good engine?   Was it a Suzuki  design, or was it a Sachs or
something.    What was the power?  the weight?  did it have aluminum side
housings? rotor?   Was it liquid or air cooled?   As I recall... perhaps
incorrectly it was a single rotor........   Somebody around here no doubt
knows something about them.......  seems like a potentially useful UL
engine..........   Not everybody needs or wants 300 HP.

Search the web. There is a whole Suzuki rotary sub culture. One of my hangar mates
has one. Water cooled one huge rotor. Suzuki  design. All I know.

I have 2 of these engines. They are water cooled, single rotor units with aluminum
end housings. There are anough big bolts holding it together to suit a 
1000 HP marine engine.

The SHORT block weight is 62 lb. dry. It is listed at 62 HP @ 6500 rpm. The peak torque
is given @ 54.9 ft. lb. @ 3500 rpm. The volume is given @ 30.3 cu. in.
I have one factory new short block, and one complete engine assembly. At this point
the core engine is also at short  block stage.
It is a beautiful peace of work, but also a lot of work to power an aircraft.

Basically it is a dry sump design. 
Oil is dumped out of both end housings on one side into the gear box,
and on the other side into an end cover that also supports the alternator. The oil
then collects underneath in an connecting  oil pan.

All accessories are gear driven, and are on the gearbox side. The redrive would best
be taken of the alternator side in which case you would lose it. If  
power is taken off the gearbox side an offset drive would be required.

I had intended to use this engine on my single seat taylor monoplane, but the amount
of time it would take to do what has to be done I don't have at this time.
To start with I am going with a 1650 cc. VW geared down 1.71 to 1. using  a honda
1000 gold wing primary drive.
