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

Improve your Aircraft’s performance with our 3 blade propeller designed specifically for Lycoming O-320 to IO-390 powered aircraft such as Glastar, Sportsman and other similar aircraft. This propeller is manufactured using a 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 stainless steel 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 users to set a broad range of pitches, without need for a protractor. This 3 blade propeller is suitable for use on the Lycoming O-320, O-360 and IO-390 and similar engines. We have tested it up to 210+HP. The blades can be trimmed from the maximum 73.5″ diameter to 69.5″ diameter. We have a composite spinners available for this propeller to match up to the RV cowling. This propeller mounts with 3/8″ & 7/16″ & 1/2 bolts only! Please specify bolt size when ordering.   NOTE: Sensenich carbon propeller hubs are not compatible with Sensenich metal propeller spacers of 4″ length.  We have been unable to locate a commercial source for long enough bolts to go all the way through the propeller hub and spacer. Sensenich recommends Saber Manufacturing, which offers a 4″ spool propeller extension which fits on Lycoming 4 cylinder engines.  It is a double flanged propeller extension. http://www.sabermfg.com/extensions.htm  6″ diameter, 4″ length Saber can also provide a bolt kit to mount the spool onto the engine.
