The new three-bladed Top Prop system utilizes blended airfoil technology to improve virtually all levels of performance

PIQUA, Ohio – ­ February 3, 2005 ­ Hartzell Propeller Inc. announced today that a new three-bladed propeller conversion kit is available for landplane versions of the Cessna R172K Hawk XP aircraft.

The new 75-inch, three-bladed propeller system from Hartzell replaces the original equipment 76-inch, two-bladed McCauley system.  Hartzell¹s testing demonstrated improved take-off acceleration through 55 KIAS, increased maximum rate of climb performance below 10,000 feet, and a 1-3 knot increase in cruise speed at 60%-80% power settings.  Another notable improvement is reduced diameter for better tip clearance and reduced blade erosion

In addition, the Hartzell kit is compatible with the popular Isham STCs that increase R172K engine ratings up to 210 HP.

As with most Top Prop propeller systems, the new kit provides an improved 2400 hour/6 year TBO as well as the exclusive Hartzell Plus Three warranty which provides a full three years or 1000 hours of coverage. List price for the complete kit is $8995 and includes the propeller, polished spinner, and STC paperwork.
