I think you should make a Twin RV-4 with these engines. Surely you would
be the first to the starting line. Alas, like Bob Dole, you might not be
able to get it up.

Somebody want to calculate the propeller for 108,920 hp at 102 rpm?

I bet they have a special security detail tasked with eliminating vistors
who call these "motors".

Ass-uming a single engine, chain-driven, counter-rotating prop config... Your
2-bladed wooden props would only be 13.25 miles in diameter... each. Now
assume a plane of appropriate size/design and you have a Wright Flyer with a 66
mile wide wingspan. Or 1452 square miles of wing area...

maybe I'll stick to gliders...

What RPM would they turn? We have to keep tip speed under mach.

You'd have to de-forest the entire state of Washington to build it.

I think the tip speed would under the visible spectrum. :)

Prop RPM? Oh, that's an easy one... 330-335. Everybody knows that one...

Boy... go get my chainsaw and a bottle of glue.

Now that can't be right...

If the prop is 13.25 miles in diameter, the tip distance traveled is
41.6 miles per revolution. Mach at 13.25 miles altitude is 662 mph.
So you can only do a max of 16 revolutions per hour, or .26 RPM, and
keep the tips under mach, assuming no forward air speed.

(Is 330-335 what the original flyer was running?)
