Ask us about propeller balancing!
After realizing the upcoming season was going to require a couple customer props to be sent out for overhaul I decided i should invest in my own balancing computer rather than hire an outside source.
A dynamic propeller balance is done using sensors connected to the engine with the propeller mounted and your engine running. Most propellers are static balanced at the overhaul shop but thats far less accurate than a dynamic balance completed with the plane running as it would when you would have a vibration.
The vibration difference between a balanced propeller and an unbalanced propeller can be night and day. Prop balancing has a flat rate of $200/prop.
