3 Blade UL Power Ground Adjustable Propeller

Improve your Aircraft’s performance with our 3 blade propeller designed specifically for UL Power 390 and 520 series powered aircraft such as Super Cubs and Zenith 750 Super Duty. This propeller excels from STOL to light sport speeds. This propeller is manufactured using an internal pressure, closed mold system to produce a hollow, one piece blade.   This process yields very repeatable blades with maximum strength, durability, and low weight.  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 Pin Hub System allows its users to set a broad range of pitches, using the system’s index pins to make adjustments. Simply loosen the hub clamping bolts, insert the desired pitch pin, set the blades against the pin, torque the mounting bolts and go flying!  The entire pitch change process takes less than 5 minutes.

This 3 blade propeller is suitable for use on the UL Power 390is, 520i, and 520is engines.  The blades can be trimmed from the maximum 69.5″ diameter to 65.5″ diameter.

This propeller mounts with 3/8″ bolts only!
