I like Zinger props, good wood, and lots of it, to start reshaping for what want. Usually, a bit of undercamber and radius on the leading edge and thin the trailing edge and you have a winner. Careful balance, too.
For electrics, the hub hole is just a hint too big. Just enough to screw up the balance. A wrap of scotch tape on the shaft seems to fix that. Properly set up electrics should have NO vibration.
