Did a couple of RV prop balances yesterday and thought the results were interesting. One engine came from Matituck and one from PennYan. The crankshaft 2.0x tell the story on internal engine balance (piston/rod matching weights primarily). There are no "limits" on this and we are talking small differences but interesting to see.
Both aircraft were out of limits on propeller vibs, both ended up with great final numbers of 0.010 and 0.011 IPS after just 3 runs
Both aircraft owners will definately notice smoother operation based on the large decrease in first order (prop rate) vibration.
