Paul, Are you familiar with the Mistral 2 and 3 rotor aircraft
engines being developed in Europe. Do you know what is different from
the Mazda engines that you have worked with and what they are doing?
Thanks
Julian Morrison
They are near identical to the side port Mazda's. P-ports would have
given them 20% more power.
They attempted to FAA certify the rotary for 15 or 20 years which
was an economic mistake. They ran out of money. They should have just
sold parts to the experimental market. There are a few videos on my
youtube site. See the key search word below.
Here are some pictures from the factory in Geneva.

Julian, I had just chatted with Mistral, they claim certification now
and from the prices for engines they are quoting it sure seems like
it. Their engines are bit heavy for the power output. I agree with
Paul, P=Ports would have been a better approach and better power to
weight ratio. Robert Jones
There is US certification and EU certification. Typically when
automotive parts are used in EU certified the engines are not allowed
to be overhauled. They must be thrown away after a certain number of
hours. Typically 1500 hours.
Actually this makes a lot of sense with a piston engine. Even tho a
piston engine crankshaft does not have cracks at TBO it may develop
cracks after a few more hours use.

Robert,
I checked with them last year and they quoted approximately $60k us for the G-300, 3
rotor, 290 lbs, 300hp experimental engine at that time. I think that is crazy for an
experimental engine. It’s a nice looking package and I’m curious about the PSRU that
they are using, where the extra weight is coming from and how unique the ECUs are to
name a few?
I attached the emails from Mistral below just for reference.
Thanks,
Julian Morrison

Attractive cost of ownership: 3000-hours target TBO, fuel consumption
optimized in all flight phases, reduced average fuel bill.
Engines prices and delivery time are as follow:
G-300 list price is 56’000 Euros (VAT excluded) . This includes
the complete electronic Engine Management system (FADEC), with two
ECUs and complete wiring harness, starter system, one alternator (28V

They build their own gear box (PSRU).
For that kind of money I would expect p-ports and aluminum end housings
and 375 HP NA.
