Agree. On the first DynaVibe run, the prop was 0.14 ips. I was surprised that the prop DynaVibe’d that well with only the static balance. So I made several more runs and obtained similar results. I added 20 gm where the DynaVibe indicated. I was stunned and very pleased when the result was under 0.1 ips. So made several more runs under 0.1 ips but could not obtain clarity for further weight placement. My original goal was 0.1 ips so I’m very pleased with this result. BTW, the prop tracks to less than 1/8 inch. I would be very interested to know the prop balance experience of other radial drivers.
