Hi Nick,
You should contact Mistral and offer your plane as a test bed.
At the present time they are pursuing the certification of the TWO rotor engine.
Next in line would probably be the two rotor turbo as 90% of
the cert work would already done from the N.A. engine. Their
test bed plane is a SINGLE ENGINE Piper something or other that
can support the weight of the two rotor engine because it is
similar in weight to the Lycoming it replaced. With the increased
weight of the three rotor, it's likely they will need to find a
larger plane for testing. Keep in mind, this would put your plane
in the EXPERIMENTAL class and you could not use it for commercial
purposes until it was restored to the original configuration and
reinspected. They seem to do a lot of the test flying around their
facility near Daytona Beach, FL.

No longer Dave. The Piper Turbo Arrow crashed. Non certified muffler
melted and plugged up. Several months after I went for a flight :)
They now have a Maule now I think. Nick may have missed an opportunity there.

Nick, I have a question for you. When you overhaul those TIGO-541 what
parts must be replaced in the gear box? What is the TBO time anyway.

Hi Paul,

We are currently certifying our normally aspirated three rotor
engine (see www.mistral-engines.com). The two rotor (G-200) will be next in line.

You are correct: we have acquired a Maule and are currently
mounting the G-300 into it at our DeLand facilities in Florida.

Best regards,

Thanks Perrine. I'll stop in on the way to Sun n Fun and
get some pictures if you don't mind.
Here are some pictures of the fine Piper installation.

Hello Paul,

Thanks for all the pictures of the Arrow.
I guess our team in DeLand would welcome you warmly.
I am copying them on this email to put them in the loop.
See you soon.
