Maybe we can get it down to TR speed with a differential and then a planetary set for the remaining reduction for the MR

2 stroke wankel? Now that I got to see :-)

Easy.  Go to http://www.uspto.gov/ and search for patent number 5,251,596.  My inventor friend has promised to set up his prototype again for me to take pictures for the list, but he is busy all over the country with his various projects so it could be months.

My gut feeling is you ought to go with a turbo 13B two seat first as
you need to convince a lot of people that a rotary works.
Keep it simple. The simpler the better at first.
You should get better performance than the helicopter everybody will inevitably
compare it to. Mainly the Robinson R22.

I think you are right.

If I were doing it I would buy an R22 and install a rotary with a Ford planetary
as a demo prototype. Get some PR on that and sell a bunch of stock :-)

I don't think this is very feasible, more power means you need more antitorque, etc, and the added mass of the 13B would strain that toothpick machine.   Agreed on stock sale though :-)

MecanAir will have the rotary certified any day now by using the European loop
hole reciprocal certification agreement with the FAA. Apparently auto engines
can be aircraft certified in Europe. Buy engines from them at first and then set
up an engine shop in Europe.

Exactly what I have been thinking.  I need to learn more about this loophole.  We also need start making our own lower cost aluminium endhousings.

I found the patent but I don't have the right plug in. Can you save the drawing
as a gif and upload it here? How does it work?
