Verner radial vs. Rotec radial

[mickey]

Reliability with the Verner is certainly a concern, since it'll be my narrow behind up there.

Another slightly less "out there" idea:

How about a Rotax 914 turbo with electronic fuel injection and ignition? Fully redundant computers are an option. He uses an oil-to-water cooler, so you only need to worry about a radiator in the airstream.

As you can see, I'm not somebody who is content with the status quo. But I've got good life insurance.

Edit: If the Verner engine fits inside the standard "bubble cowl" then drag and frontal area won't be an issue. That's a big "if", though, since I can't find any info on the diameter of the engine.
