Warp drive moment of inertia

[pt17]

Was supplied with a 72inch 3 blade nickel edge square tip warp drive prop. After hearing that this prop is not suitable for a rotax 912ULS, I tested the moment of inertia. Sure enough it exceeds the rotax installation requirements. 7000 vs max of 6000.
I am now looking to replace the blades with lesser diameter or with taper. I want to keep the nickel leading edge. (seaplane ops) Anyone have a 70 or 68 inch with or without taper, and know what it's moment of inertia is? Warp drive don't publish this important info.

Thanks for sharing your test results. I also wish it was standard practice for prop manufacturers to publish this data. If enough of us did what you have done we could at least maintain a sticky thread here on the different configurations.
