COMMENTS: The general rule for converting a 2 blade prop to a 3 blade is
            subtract 1" from diameter OR subtract 1 from the pitch.

PER MASTER AIRSCREW: All 3- and 4- blades props are balanced dynamically at the
 factory prior to drilling. The mounting holes are then drilled slightly off
center, if required, to properly balance the propeller. As such, your mounting
hole may be slightly off center. Master Airscrew assures us this is perfectly
normal and will not cause any problems during usage.
