1940 Waco ZPF-7 N5ZP

N5ZP was originally N29904 a WACO UPF-7 with a W670 220hp Continental engine and fixed pitch Curtiss Reid propeller. Completely remanufactured by RARE Aircraft this airplane was converted to a ZPF-7 with RARE’s exclusive Ascension Package. A Jacobs R-755-B2M supplied by Air Repair Inc. with a 1400 hr. TBO was installed that swings a 2B20-9 constant speed propeller, the longest and highest performance propeller available on any F-series WACO on the market. The constant speed propeller is the only way to get the full 275 hp. out of your Jacobs engine.

No stone left unturned this is a completely new airplane. All new wings, fuselage wood, hardware, control surfaces, fuel and oil tanks, firewall, engine mount, seats, cables, wires, and electrical system to name a few of the countless replaced items and upgrades.

This aircraft was the vision of Keith Kocourek of Wausau Wisconsin. Together the RARE Team and Keith created this beautiful example of a ZPF-7. It has a complete set of log books and real history along with a new lease on life with its fresh makeover to better than new status. We are very proud to have N5ZP and Keith members of the RARE family. The vision and drive supplied by Keith is a very important part of what makes this airplane so special. Its custom paint scheme is best appreciated in person. A deep insignia blue contrasted by the light cream and gold pin trim is simply stunning.
