Interesting! That may explain my difficulty in getting a clear o'scope picture from accelerometer.=
Need to first remove any flywheel/engine imbalance that may obscure prop imbalance.

=20 Matt,

One cannot balance the prop by placing the balance weights on the flywheel due to the gear ratio of the psru.=C2=A0 I chose to dynamically balance at the flywheel with the prop removed, then install the prop, and finally dynamically balance at the prop. =C2=A0That appears to have given good results for me.

How does everyone balance their prop, do they gain access to the flywheel and add bolts/washers there like a standard aircraft engine? I'm looking to balance the prop around X60 (Williston, FL), and I forget who, but someone=C2=A0said we could rent one nearby?=


Had a 301 ss slip joint bellow for the exhaust and it cracked, which set me back a few months. The end of my exhaust must have too much vibration, I=C2=A0will figure ou= t more rubber mounts with the welder to stop the end vibrating. Bought a 2.75" inconel split joint bellow from SPD exhaust that should handle the heat.
