Without getting into the technical
merits, it seems quite likely to me that they did it because
that's one less change they would have to sell to airframe mfgrs.
Stock motor mount and minimal cowl adjustments probably made them
at least *think* that the engine would sell easier that way.
*On* the technical merits, don't forget that supposedly, there are
no stock Mazda parts in Mistral's engine (an attempt to meet
production tracking requirements for certification). It's a real
shame that they didn't try to sell to homebuilders as soon as they
had a tested engine. They might have generated enough revenue to
stay afloat, and be a real player in the certified market as a
result. Same thing happened to LoPresti when he tried to bring the
Swift Fury to market. If he'd simply produced the original
airframe with only existing STC'd canopy & big-motor mods, he
could have sold hundreds of planes and easily funded certification
of what was effectively a new airplane type in the Fury. Instead,
he held out for the updated type cert, and the venture failed.
