PS I've never heard of anyone handproping a 912 even though it has a gearbox. Anyone done it?
Yes. I've done it twice on the 80 hp but that was before I read you couldn't do it. Now of course I wouldn't even try. I was much younger then too.
BTW, I've been living with my Rotax decission for 14 years and 2,500 plus hours of reliable, cost effective , fuel efficient, low maintenance very enjoyable flight. My engine decission worked out great. Hope yours does too.
