Huge thanks to Dorsal for renting out his DynaVibe!

I used it on my Kitfox Super Sport with Rotax 912ULS and in-flight adjustable IVOProp.

The initial DynaVibe averages were in the 0.25 inches per second range.

After several runs and weight additions, my final averages were 0.05 IPS for climb pitch at 5400 RPM, and 0.01 IPS for coarser pitch at 5200 RPM. I thought I would never get the vibration down that low.

Time will tell if I feel any difference in flight.
