What have you heard and/or experienced regarding use of a variable pitch Ivo prop with a 360 Lycoming in a Zenith 801?  I will appreciate all comments, thoughts, etc.  Thanks, Ed

You can ask directly to Ron at ivoprop dot com, unless you really want only users comment. I have a 3 blade Medium Ivo inflight adjustable with a constant speed controller for a 110 hp but haven't flown it yet.

I run a Ivo prop on my 801.... So far I am impressed, but I only have 430 hours on the plane.

Never had an IVO on an 0360. Had IVO Magnum 2 bl. electric in flight adj. Welded H.D. all thread off the alternator, toggle dash switch, changed brushes out app. 50 hrs., on another dope & fabric E.A.B. Whenever I had any tech. Q., brushes, I called H.Q. in Belleflower, Calif., who I'd suggest for further info., in the event you haven't. A lot of the Desert Kitfox Search & Rescue in Maricopa, AZ. run the IVO on the 912ULS, opting for the lighter version-the Patriot, lighter than the  Medium or. the Magnum. My 66" 2 bl. =22#4oz., per rods in the blades obviously.  Also had an IVO in flight adj. on a Subaru EA81 that was fuel inj. & turbocharged @ 150 H.P., 30 less than yours.With Beta, on floats, can reverse, slow down when close to dock.

When I bought a capacitive discharge ignition from Lightspeed Engineering, I asked about prop recommendations. They had nothing positive to say about IVO prop on any engine. But then, I have no personal experience.
