The bottom line is you need to test this before you do it
at OSH. The rotary may not be a bullet proof as you make it
out to be.

BTW we take a 12A rotary apart each day and put it back together
at the Sun N Fun engine work shop. I am a volunteer in that
work shop. OSH is too hostile and arrogant for my taste.

Paul:

Part of the suspense is that it HASN'T been tested.

To succeed, it only has to run for two minutes -- twice as long as any
other water-cooled engine will.  We know it will do that.  The Wankel
has run significantly longer than that in the wild.

The only real risk is melting the housings, and there isn't really
enough heat for that unless we pour on the power (which we won't do), or
breaking the apex seals, and if we start with a known-running engine,
that's not likely either.

The "Big Show" arrogance is one of the reasons to do this at Oshkosh.
It doesn't matter how well you show elsewhere, you're nobody until you
get to Airventure.  SNF, CS and Watsonville are like the regionals for
Miss Universe -- cute, but nobody pays much attention outside the local
area.  You have to go to Oshkosh to get the tiara.
