Just for your information, I could not find a loaner DynaVibe unit. I had no other choice than buy one. If somebody needs a loaner DynaVibe, let me know, I may be able to help.

I'm curious, Peter. Do you have the little skull-cap spinner with your Ivo?
If you do, how will you add balance weights to the prop assembly? That's been the problem with the Ivo's that I've been asked to balance.

The ivo in my opinion is one of the easiest props to static balance. There is a great You tube video on how to.
My ivo had a blade 11 grams lighter than the other two. I was able to get each blade static ,centroid and total weight balanced to within a fraction of a gram of each other by inserting a weight inside the torque tube at a predetermined point using a fibreglass rod to stop the weight migrating outwards.well worth trying As has been mentioned there is limited places to add weight externally.
I'm sure that's all true, Dusty, but doing a good dynamic balance job on an Ivo with the small spinner seems very difficult if not impossible for a guy with a DynaVibe or any dynamic balancer. I've very rarely seen a propeller that has been well-balanced statically that couldn't benefit (sometimes greatly) from a dynamic balancing job. Since the entire rotating assembly is being balanced, the needed weight is most often not even in line with the propeller blades. At least that's been my experience.

I had a friend balance his IVO by adding layers of paint to the tips of the blades.
