Other than the redundant power a part 103 gyroplane with a good pre-rotator could fill most of the above list of wants.
Regarding the 60 Hp VW engine: (thread drift)
I've got all the needed tools, a collection of cores and the experience to build them.
Unlike Pops I've just never been able to emotionally bring myself to feel comfortable with one for aviation use. I've seen too many broken ones over the years, both ground bound and aviation converted. I know there is nothing fundamentally wrong with them - it's just my personal problem. A purpose built head and a tweaked version of the Force One hub would go a long way toward making me feel comfortable enough.
