Paul,
I walked around the homebuilt area several times seeking
rotorheads, but only found a couple.
Ran into Atkins, and then Dunlap.
Did I miss something? or was that it for rotary power?
Archie

That was about it. Did you get to the Mistral tent?
Also a P-port 2 rotor Velocity went 205 MPH in the 400 mile Dayton to OSH race.

Actually that's not quite true.  I did the same walkabout through the homebuilt
area and found not much except Mistral's tent and a few aircraft.  I then
stopped by the Contact magazine booth. They mentioned, and I subsequently
visited, a booth out near the main road to the museum where Rotary Aircraft
Engines www.rotaryae.com had a few samples mounted on auto gyros and a
motorcycle. Prices are up in Mistral's range.

Why were they not in the real show?
They have been around for years. IMHO they have some sort of association
with Moller. I have never seen a real one.
Looks like a bunch of wood mockups to me. If it were real
that belt drive would be a hazard to the e-shaft :)

 Are they selling stock? :) Is Barger  Moller spelled backwards? :)

Very low power ratings for their displacements, short intake runners. "RAEs
development partner, Rotamax" quoted from their site, isn't that Moller ?

Maybe this will help.  The parent company is called Fan Cool.  They build
apu's to drive coolers on semi's when they're parked.  RotaMax is their
marketing name for their line of rotaries.  Yes, the original basis for
their engines did come from Moller.  It is important to understand that the
RotaMax engines are NOT the same engines that Moller was running in his
"SkyCar".  The RotaMax types are charge-cooled and liquid cooled.   They run
in two displacements:  a single of 650 cc and a twin in 1300 cc.  They are
rated at 85 and 170 hp.  I have not seen the weights on their Bloc II
lightened engines.

To the best of my knowledge, RotaMax does not currently
offer a turbo version, but one or more of the OEM's they've been supply beta
engines to for evaluation may have been playing with turbos.  They've been
concentrating on getting OEM industrial type companies interested in their
engines.  I've seen run data on the two-rotors set up as generators and the
outputs seem reasonable.  Apparently the carb versions (what you see in the
photos from OSH) don't turn on all of the OEM's, so they have been working
on a Bloc II engine using fuel injection and are lightening the engines even
more by going to a lighter flywheel and starter.  I suspect that the latter
will be geared, but don't know this to be the case.  To the best of my
knowledge, Moller doesn't really have much to do with RotaMax.  Apparently,
RotaMax is required to pay a royalty fee to one of Moller's companies based
upon sales.

A friend of mine from out-of-state sent me a copy of one of
those filings public companies have to send in quarterly to the SEC from one
of the Moller companies.  Moller states that revenues from the RotaMax
licensing deal are coming in slower than anticipated.  I have noticed one
encouraging sign.  The RotaMax people don't seem to be much on publicity.  I
find this a bit refreshing.  They also don't seem to be trying to hustle
stock - refreshing again.  As a privately held company, it's difficult to
tell how well they are funded.  Trying to focus on industrial applications
to get volume and cash flow going makes sense to me.  They are willing to
talk to hovercraft manufacturers.  I do know that a NEOVA with one of their
engines did static trials in Indiana last year.  Haven't heard the results.
Phantom aircraft has talked to them about using one of their engines in
their two-seat ultra-light versus the AIXIRO that had a major failure after
135 test hours.

The RotaMax's run up at 7750 stock.  I don't believe that
RotaMax is going to be in the gearbox business, so everyone gets to figure
out their own drives (like this is new).  How many of these engines are out
there?  My understanding was that 200 Bloc I engines were scheduled.  I
don't know how many were actually placed as beta models.  The Bloc II
engines were intended for June-July of this year.  I was told very recently
that August is more likely.  When the specs for the Block II are released
I'll post them on the board.

This has been festering for years. Production in xxxx. When xxxx comes along then
it is production in yyyy. They are taking instructions from Moller.
Moller has been promising a sky car for 30 years.
The memory span of the interested parties is limited and a new sucker is
born every minute.

When I see an airplane flying with
one I will start to believe they are something other than a stock scam.
Then they are going to have to demonstrate at least a 500 hour TBO.
Rotary engines that work are harder to make than they look.
