Matt,

One cannot balance the prop by placing the balance weights on the flywheel due to the gear ratio of the psru.  I chose to dynamically balance at the flywheel with the prop removed, then install the prop, and finally dynamically balance at the prop.  That 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 said 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 will figure out 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.
