Those bushings were part of the problem, I think. They prevented the plates from grabbing the blade itself, but those blades were 95% foam with a really thin carbon skin on them. Some of the props threw blades, the centrifugal force tearing them right off the bushings. Are the IVO blades more substantial at the root now?The early IVOs had issues with non-knurled squash plates and bushings causing blade shifting. Zero problems with mine and I have dozens of customers flying IVOs, also with no issues. Mine has the knurled plates and no bushings.
The other thing I didn't like about the IVO was that all the pitch change was in the outboard sections, exactly the opposite of what is needed. Even a variable-pitch/CS prop rotates the entire blade the same amount, when what is really needed is a blade that rotates more near the root and less at the tips, to maintain an even AoA across the span. Trigonometry.
