Propeller Maintenance
Propeller damage is caused by striking solid objects. If the propeller is not rotating
at the time it strikes a solid object, the damage is usually confined to just one blade and
may be dicult to see. If the propeller is rotating when it strikes an object, usually the
resulting damage can easily be seen on all blades.
Checking/Repairing Propellers

ed.
Step 2: Clamp a small rule scale to the shaft strut, parallel to the shaft so that the end
