As you see the engine at this stage it weighs in at exactly 45 Kgs
or 99Lbs. It has one piece ceramic seals, and estimated to put out
in the region of 130 hp @ 7000rpm. I will post more photos as the
project progresses.

How do you drain the rotor cooling oil into the oil pan? since the
original side housings do not have provision for that.

Richard Sohn

Excellent question Richard.
A reflection of your vast experience with one rotors.

The drain backs are built into the front end housing in the iron
version as well as the RB aluminum version.

The gear teeth are not now needed on the front main bearing
holder. They could be ground off to improve the drain back slightly.

Hello Richard Sohn, as you can see there are people, including myself, that are very interested in the one rotor rotary. You put a huge
amount of work into designing your engine, many years ago now. I was hopeful to see you offering parts or complete engines
for sale. Was your engine a one off, will you offer castings and other parts ? Curious minds want to know !
