Paul,
Here are some photos of the Cosman prop. Tractor, reverse rotation 2.17,
72" diameter, 88" pitch. The blades are carbon, the hub is
hardwood/composite 9" in diameter and 5" thick. The mounting holes still
have to be drilled. The pitch twist is maintained all the way to the
hub, as it is in ducted fans. I will be sending it to you for testing on
your test stand when it is ready.
