Hi Steve,
If it's not too much trouble, there are a lot of guys hoping you will take the time to test the MMOI on your prop. You have a very large following and a lot of guys sitting on the fence waiting to buy props but need to get an idea of the MMOI on the longer Prince props. The guys really trust your opinion on performance, but don't want to risk unnecessary gearbox repairs. It's a pretty quick and easy exercise to do it using the Rotax instructions. Just hang a couple of 72" safety wires from the rafters 12 inches apart, hang the prop using a small wood block and set it oscillating. Count the time for 30 full oscillations and use the graph to get the MMOI.
Thanks,
Dan
