The article made is sound like Mistral made all the parts and nobody else ever put a Mazda 3 rotor in an airplane before :)  Perhaps Kitplanes is angling for a Mistral ad. Don't hold your breath Kitplanes :)

I never saw a Mistral engine that did not have at least Mazda rotor housing and may be all the other Mazda end and center housing are on Paul Janssens's  engine. I have seen lots of Mistral engines in the US and all over Europe in shows.

The rotor housing coatings are nearimpossible to coatfor that size engine without the Mazda steel liner. I could be proven wrong but I would have to see 2000 hours in aircraft service on a coated housing.

The only part that cracked was the Mistral cast oil pan. There is zero load on the Mazda oil pan unless somebody forgot to install the  large hollow dowel pins between all housings.

However Kitplanes is turning into a great experimental aircraft magazine ten times better that that fluff job EAA Sport Aviation rag :)

Here are some factory photos.

As far as know they may still be in biz technically  but they are definitely inactive.


How many people on here buy kitplanes magazine?
