INCLUDES: One Master Airscrew 12x8 3-Blade Glass Filled Nylon Propeller
SPECS: Diameter: 12" (305mm)
Pitch: 8" (203mm)
COMMENTS: The general rule for converting from two blades to three is to
decrease diameter by 1" and increase pitch by 1"
PER MASTER AIRSCREW: All 3 blade 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, the mounting hole may be slightly off center.
Master Airscrew assures us this is perfectly normal and will not
cause any problems during usage.
