I worked with a local shop on prop balancing and I'm wondering if it's correct.
I'm running a Hartzell constant speed/blended airfoil prop and the plane seems to have a slight buzz between 2300 and 2500. When I asked the shop about it they said they balance all props at full power and if it's in balance It'll be good throughout the full range.
Anything above 2500 feels smooth and the full power balance run only produced a .07 and was told nothing needs to be done.
I was thinking about putting a bolt on the ring gear as the solution that was given on the machine was adding 6 grams at 42 degrees but with bolt holes at 30 and 60 degrees I'm not sure if I should do anything.
