Propellers
Here is a new spin on propellers. We recently bought a new Sensenich Propeller from Fletchair that was stamped 61 but turned out to be a 60. Sent it back and had it adjusted.
One of our members has an AA1B with a 160 HP engine and his engine shakes. Even after dynamically balancing it still shook badly at certain RPMs. Finally took it off the plane and send it to a prop shop. It was in static balance (equal weight blade-to-blade), but the profile was off due to one blade having 3 coats of paint and the other several more, thus creating a different airfoil. Propeller was stripped and overhauled and now is smooth as silk.
Finally when it comes to Dynamically balancing a prop, the ring gear has holes that are at 5.5 inches from the center. SInce prop balancing assume weight at a one-foot radius, 5.5 inches is only 0.458333 of the way there. So devide your test weight by this to get the real weight to add. FYI. Theory, 5.5/12 = 0.458333
