Founded in '96. I applaud the Ruud family for purchasing it and seeing it through. God bless people with seemingly endless money to see projects like this through.
 
Engines like this seem to be just a pipe dream, always "starting production in mere months order now !!111!". Would be nice if they were though.
 
our design was to part 33 standard for certified aircraft, which added a lot of cost such as vibration analysis, structural analysis. ect...we used a bigger than needed v8 for a number of reasons, one being we could install it on almost all certified aircraft requiring 180-350 HP with just software and PSRU gear ratios.

mosaic didn't help our challenges as it specifically excluded prior certified aircraft, unlike primary cat which targeted certified. we did have a v4 design for LSA but it was obvious faa leadership would continue to make it difficult and cost to do all we wanted to do for such an engine was too expensive and other companies within that segment besides established rotex were struggling.

the LSA mosaic category dosent allow, in facts prohibits, cert conversation. This wasn't the plan about 2-3 years ago but the industry and faa wants old piston scrapped for different reasons. Too bad really, as canada has a neat thing called owner maintain that allows this and owner mx, much like the primary conversion we got here in US.

also to bad as there's a lot of cheap cert airframes that could fly great with a new modern engine. we loaned our exp c172 for a few young aviators running low on funds recently, both trained and passed their ride for a commercial and a initial cfi for a fraction of the cost....that was our first CFI ride and he is first pilot to train and pass the CFI ride in a exp c172! we figured it would cost about $18k to go from zero to cfi in a converted c172, which would have help build GA back.

I expect the lsa cat will be the future trainers going forward as cost remains biggest obstacle to fly.

Ask a Mooney Porsche pilots how it worked out.

Porsche was a good example of faa protecting legacy manufacters in many aspects...back then faa certs were more stringent to obsolete cert basis as VAR 3 and 33. .now a applicant can write asking for alternative methods to demonstrate compliance which use more modern and cheaper means. As a DER, much if our work involved coming up with , and negotiating, such alternative means to reduce time and $ while still meeting same basis as legacy. This can get very technical but can make or break a program.

...most don't know that Toyota actually certified a conversion engine based on Lexus V8, and also pulled the plug after years of development and PAM a fraction of what it was....it didn't make sense considering the extra components added to meet cert requirements especially for an engine with millions in long service....and of course the liability factor.

but others have certified auto conversions such as the diesels.

wouldn't it be great if you could drop in a certified Toyota engine in your c182!?
