3 Blade Lycoming O-320/O-360 Ground Adjustable STOL Propeller for experimental aircraft

Improve your Aircraft’s performance with our 3 blade propeller designed specifically for Lycoming O-320 through IO-390 and Titan O-340 through IO-370 powered STOL aircraft such as experimental Super Cubs and Zenith 750 Super Duty aircraft. This propeller is manufactured using an prepreg compression molding process on foam core to produce a stiff, one piece blade. This process yields very repeatable blades with maximum strength, durability, and low weight.  Don’t confuse this propeller with other propellers that are manufactured as two pieces and then bonded together afterwards.  This propeller has the strength and durability to give you thousands of hours of trouble free flying. This propeller features a co-cured bonded metal leading edge for erosion and FOD protection.  The two piece hub is manufactured from aerospace grade aluminum and is shot peened for durability and anodized for corrosion protection. Our Pitch Gage System allows its users to set a broad range of pitches, without need for a protractor. This 2 blade propeller is suitable for use on the Lycoming format engines, from O-320, O-340, O-360, IO-370, O-375 and IO-390 engines.  We have tested it up to 205HP.  The blades can be trimmed from the maximum 79.5″ diameter to 78″ diameter. We have 12″ and 13″ composite spinners available for this propeller. This propeller mounts with 3/8″, 7/16″  & 1/2 bolts only!  Please specify bolt size when ordering.   NOTE:  This propeller is intended for experimental category aircraft only and does not include 8130 documentation!.
