I mentioned this a year or two ago, how about building an Ivo like prop,
with a better blade cross section that is properly pitched for top speed and

I like the basic idea, but the ivo as implemented has some very basic problems.
Conventional wood props use the 'lugs' which surround each bolt to hold the prop stable in the hub.
With the ivo, the blades depend on clamping force to hold the blade stable in the hub. Contrary to popular myth & metaphysics, this clamping force is not adequate to prevent movement in the hub. If the design could be converted to a one-piece prop taking the torque loads through the lugs it would be a much more viable product.
This issue may not be as significant with the rotary as with a Lyc, but it still makes me very uncomfortable.

been there, done that with the ivo
