Hartzell's 7391 'Scimitar' blade, the choice of Hawker Beechcraft for the 50th anniversary special edition G58 Baron, is now available for all Baron 55 models, as well as earlier 58 models as the key piece of the Top Prop conversion. The Hartzell kit features Scimitar aluminum alloy blades, derived from Hartzell's Reno Super Sport racing design. The blades provide extra ground clearance and a noise reduction of 5.8 dBa, as compared to its original 84-inch two-blade prop. Installation of the new prop also typically results in a two- to four-knot increase in speed at high power settings.
The Top Prop propeller kit is available for Beech Baron models 95-55, 95-A55, 95-B55, 95-B55A, 95-B55B, 95-C55, 95-C55A, D55, D55A, E55 and E55A.
Available directly from Hartzell or through Hartzell’s Top Prop dealers, the 2011 list price for the kits, which include new pointed, polished aluminum spinner assemblies, range from $21,500 to $26,850 depending on propeller model and extra equipment. Hartzell says kits are available with 14V or 28V de-icing systems or fully compatible alcohol anti-ice systems with newly designed slingers and stainless steel travel tubes.
