The propeller we have all been waiting for just arrived. And it is a beauty!

This new prop really looks the part of the Hamilton-Standard blade design from 1942.

One big reason the production took so long is that Jim Rust (Whirlwind Propeller - El Cajon) is such a stickler for efficiency. He tweaked the airfoil design many, many times in order to get it at what he considers the peak or max efficiency available with the current state-of-the-art.

The diameter, blade twist, pitch angle, were all worked, and re-worked until he hit the "Goldilocks" zone..."It's Just Right".

I admit, it was frustrating for me, waiting for 3+ years to get this. But all of us here (even my wife) are absolutely thrilled with the final product. In combination with the LS376/480, this should be "off the charts" performance wise.

The total weight is 55 lbs, 20 pounds more than the 84" propeller. Gearbox + Prop = 145 lbs. 90 inch diameter. Both the prop, and the hub, are super High-Tech.
