Hmmmm, If you are running the paddle blades you can slightly shorten
one to get it in balance because the paddle blades are blank on the

place the weights under a prop bolt. I guess the question is,,,why no
spinner???

We had an IVO prop on a Glastar and couldn't get it to stay
balanced. The blades, being held by only two bolts each, can move (or
swing) chordwise in the hub just enough that the assembly ends up being
off-balance chordwise, and no amount of spanwise balancing will fix it.
Even with those bolts torqued to spec we had blade movement between the
plates. Fretting was evident on the blade bushings and mating plate
surfaces. Scared us.
Too bad, since the prop pulled well, better than the Warp Drive
that replaced it. The Warp was so much easier to balance but presented
more hassle when changing pitch.

Did you have the knurled plates? Early IVOs did not. All late
production have knurled plate front and back - much better blade
affixment.
