When it really gets down to facts, most often aircraft engines really
don't cost any more than auto conversions and the aircraft engine
appears to be more reliable.
No redrives needed, redundant ignition and lots of other things that
makes them better.

I was a firm believer in auto engine conversions but i haven't seen many
last a long time except for the Subaru and Rotax engines.

I just think hanging a prop on a crank directly is a non-starter in
the first place...especially on a crank and case not specifically
designed for this in the first palce. Maybe a good redrive and flywheel
would be a better way to go?


That is my opinion, also.
