I have no idea if there are plans and castings for such. But O.S. did produce commercially a .30 sized one for aeromodellers with deep pockets in the late 70's / 80's so the principle must work on a smaller scale quite well.

Here is a parts list. **LINK**

And a pic of one :-

And a few facts. http://modelenginenews.org/drj/os_wankel.html

Hi Mike,

There are a full set of drawings in the the Aero Modeller

annual book 1970-71 on page 64. Described as

Polish 10cc Epitrochoidal engine data by Julian Faleciki.

The drawings are very detailed on 6 A5 size pages.

If you send me a PM with your email i will copy them

and send them to you.

Nick,

I take issue with the statement in your URL. Felix Wankel did not invent the concept of the engine named after him. It stemmed from a 19th Century steam engine design, and an IC engine design was produced in Edwardian Keighley by a man called Umpleby with the help of Alfred Scott (Of motorcycle fame) of Bradford in making the hardware. There is a prototype in Keighley museum. As with later attempts, the rotor tip seals proved inadequate.

My dark secret – I had an RX7 for a time

The seals were on the way out, but it just made it hard to start. Even though it wasn't the turbo version the second hand guides description of 'rotary powered rocket ship' was pretty accurate.

It was so smooth running it had a 'beeper' to warn you if you were over-revving – used to scare the life out of passengers!

I didn't have it long, I discovered the bonnet catch was faulty when it folded over the top of the windscreen as I accelerated onto the motorway. Driving at <redacted> mph with your head pout of the window and trying to get across three lanes of traffic is… exciting…
