Gerry,

I agree with you about the amount of time being wasted.

Especially, I suspect that the series of threads have worked their way around
to a search for a "traditional" direct drive "real" airplane engine--with an
implied resolution to build one if it can not be purchased new at an
unrealistic discount.

Actually, there have been any number of successfull installations of higher
reving engines with multiple v-belt reduction systems. They are probably not
especially energy efficient, and the belts are quickly destroyed if the
propeller windmills in flight with the engine stopped; but they are a cheap
and light weight way to get the job done and are easily inspected.

Personally, I really don't "like" that solution; but it is well proven for
relatively low power; but cheap and easy to inspect can save you a lot more
than a little lower friction for personal use of a small sport aircraft. So, I
would have to seriously consider that as my solution for less than 80
horsepower if I needed an engine at the present time.

As you say, it has become a nearly complete waste of time, and I expect my own
contributions to be few and far between for the forseeable future.

The more I think about it, I think the Harley is the perfect choice. High HP,
air cooled, available from crashed bikes, built with a separate crankcase,
designed with a belt drive to be used, many sizes available.
