To save weight, if an alu prop weight 30 lb. a birch will be 7 lb.,
mahogany
5.5 lb.

for efficiency, use the aluminium!

Aluminum will weigh 5 x the mahogany? Wow.

At 100-110 mph how much (WAG) efficiency would the wooden prop lose, on say
an Ercoupe?

What's the cost difference between aluminum and wooden props?

Why do people buy birch instead of mahogany?

Cool, a prop person g
