Design and Powerplant

Engine: One Continental W-670-6A 7-cylinder, air-cooled radial engine (the “U” in UPF-7 refers to this engine model).
Power Output: 164 kW (220 hp).
Construction: Typical of the era, featuring a welded steel-tube fuselage truss and wooden wings, all covered in fabric.
Cockpit: Open, tandem (front and rear) cockpits. The front cockpit was wide enough to seat two passengers side-by-side when the flight controls were removed.
Landing Gear: Fixed tailwheel landing gear. The UPF-7 featured a wider and stronger landing gear track compared to earlier F-series models, improving ground handling.

Performance and History

Maximum Speed: 206 km/h (128 mph, 111 knots).
Cruise Speed: 183 km/h (114 mph, 99 knots).
Range: Approximately 640 km (400 mi).
Service Ceiling: 4,500 m (14,800 ft).
Military Designation: A small number of UPF-7s were impressed into US Army Air Corps service during WWII and designated as the PT-14.
Handling: The UPF-7 is highly regarded by antique aircraft enthusiasts for its gentle, well-balanced handling characteristics, especially compared to some of its competitors, making it an excellent trainer.
Legacy: Although the original company folded, the Waco design was later revived by Waco Classic Aircraft, which produces modern, FAA-certified replicas of the closely related YMF-5 model.
