Is anything special as far as the rotary happening this year at
Oshkosh?   l drove up last year, bought a full week pass and was bored
beyond words after the second day.

     I wonder if RotaMax is going to do anything like putting adequate hp in
the Vampire?  Eric, are you reading this?  Its time to show off!!!  We are
all pulling for a great success for Rotamax.  I'd come to Oshkosh just to
see that.

     I will definitely make it as far as Baraboo (fifty miles south of
Oshkosh) where the Tailwinds and Buttercups  gather for several days prior
to Oshkosh.  From there, unless there is a good reason to go
on,  I think I will turn around and head for home.           Jerry

I only stay 3 days at the max. When does that Baraboo thing start? I might
stop in. This year may be way down due to the price of avgas.

Jerry,

The Sadler Vampire is at our facility and will have 100 Hrs of flight time
if weather cooperates by Osh Kosh.

It has plenty of power and our hopes are to fly it up to Osh Kosh.

A few other customer programs are progressing in hopes of being at Osh Kosh
as well.

We are working another batch of 25 engines right now and will have them
completed and on there way to various application homes in the next several
weeks.

Our website has just been updated and we will continue to add content in
each category. www.rotamax.net

Things are progressing well here with our engine program.

Thanks for your continued interest and support of RotaMax and our engine
program!

Hi Eric,

Thanks for the update. I see the turbo engines are now rated up to 7300 RPM.
Does that mean the normally aspirated engines can be run at that RPM as
well?

If so what internal changes were made?

What airport are you flying out of. I would like to see the Vampire fly.
I missed it at Sun & Fun.

Hi Eric,

Need a pilot?

Paul,

See the aviation specs on our website http://rotamax.net/downloads.html and
click on either aviation engine for operating specs as it relates to RPM,
there is no need to turn the engine above 5250 especially for aviation. We
will deal with additional HP with Turbo and or additional rotors.

Tell that to the pilots :)

Why do you say that? Your engine is obviously capable of 7500 RPM
as that is the RPM for the turbo engine version.

If you limit the RPM you are limiting the power to weight ratio.
If you limit the power to weight ratio what is the point
in buying a rotary? Pilots are a conservative bunch. If there is no advantage
to a new engine why risk it?

In these latest Rotamax HP curves the HP is still going up at 5500 RPM.
I don't get it Eric. A 80 to 100 HP 7500 RPM one rotor Rotamax would own the
entire LSA market eventually. Nothing else would come even close to cost
or power to weight ratio.
