This is probably going to open old wounds. What I would like is
experienced input on the advantages, for economic, efficiency and
longevity etc. of different types of redrives.

I am leaning towards a cog-belt reducer in a 6 cylinder, liquid
cooled, configuration driving a long drive shaft to the prop.

Yep, that is a really big can of worms.

The redrive is not as big a problem as you think. You get into a mess
when you start talking about long drive shafts.

I'd recommend (ADK) research on the BD-5 drivetrain (redrives and long
driveshafts). Not unsurmountable, but a certainly a big can of worms as
you (Jim) state.

Efficiency isn't directly affected. Weight may be affected. Longevity
will be either good or very short (vibration), but not in between.
