Paul,
At this point my rotary engine options are better if I use a
horizontal engine and a right angle gear box (bevel) with a reduction
from perhaps 6,000 engine rpm to approximately 2,000 rpm. A near 1:1
ratio is also a possibility. It needs to be reliable, able to handle
about 75-80 hp for this application, but small and lightweight for
aircraft use. I think I know my personal limitations and gear box
design is one of them at this point. Any suggestions?

My thanks to you and everyone participating.

Regards,
John McEverett

Take a look at some quad four rear axles. As I recall some of
them have aluminum housings.
