Thanks Tommy,

Good ideas and methods. I do have the electric inflight adjustable

pitch add on kit. I bought my "IVO" before it was available. I assembled

the prop with the ground adjust front plate for simplicity.

Hi Kelly,

FWIW,

Make a cardboard pattern.

If you can make the pattern close enough, you can save the cutouts to fill the gap on the backside of the prop after the spinner is installed. This may not be easy to do, but worth the effort if successful. I did not do this and wish I had.
