I spent Saturday morning trying to balance my RV6 / Superior IO360 / Sensinich setup with the same Dynavibe model shown in the photo above. However after 8 runs trying to dial in on the best balance, I discovered that none of the results were repeatable on subsequent runs! I removed all weights and headed home to ponder what could be going on.
Has anyone else found repeatability to be a problem? I was able to get down to about 0.12ips, but a 2nd trial with no change yielded 0.38ips!
Originally my setup was showing 0.42ips. The last run of the day was back to no weights, and I was getting 0.57ips. Not sure what is going on. We had similar results on a different engine and airframe earlier that week.
