> it is not recommended due to resonance vibration.
Seems odd to me that it would be resonance... Wouldn't that change with prop
pitch, blade length, rpm, etc?
Pete was correct about how the Ivoprop works, the blades are twisted
spanwise to reduce or increase the pitch of the prop. As Mark L. pointed
out, this is what is required to make a really efficient prop. So in
theory, the Ivoprop can be a very good option. Unfortunately, they have
never solved
I'll also add on to what Mark has said.
I'm considering an in flight adjustable prop but after careful
consideration I decided not to go with the IVO because of the way it
performs it's task. The IVO in flight adjustable prop varies the pitch
by warping the blade. The base of the blade is fixed
The thing about ground adjustable props is that they are not the magic
bullet that one might think. The blades still have a fixed amount of twist
in them, and simply rotating the blades around in their sockets doesn't
really change the "washout" on the blades from root to tip, it simply

Works well on a Rotax 912 but can not be used on a Volkswagen if it is a 3
blade.
I think you should refine that and say , NOT on a direct drive. I have a 3 -
blade, 60 in Dia , ground adjustable Bolly on my Type 4 rear drive, BUT, it
has a belt drive reduction.

I just installed an IVOprop and have yet to test it. I could not afford the
in-flight option, but the prop is the same. The blades have a torque rod down
the center and by twisting the adjuster mechanism, the twist along the shaft
while the base is held firm. I think it would be an excellent
