I've heard that the replica, even with twice the horsepower, can barely get out
of its own way. Big draggy airplanes want big, slow-turning props, and
apparently half the HP is OK if it's being pushed into a big prop.

That's the basic formula all WWI era aircraft used. All the pics of
them show these monster props with very little ground clearance.

Since they didn't fly very fast, it didn't matter that the props were
slow spinners.
