Wag-Aero Sport Trainer (CUBy)
These figures describe a typical build. Each aircraft of this design was built by its owner, and the one you are looking at may differ.
The Wag-Aero Sport Trainer, first sold in 1975 as the CUBy, is Dick Wagner's plans-and-kit replica of the Piper J-3 Cub: a tandem two-seat steel-tube-and-fabric taildragger with a 35 ft 3 in wing, built to take anything from a 65 hp Continental to a 180 hp Lycoming. With a 125 hp O-235 it cruises at about 94 mph, stalls at 39, climbs at 490 fpm and carries 705 lb on a 1,400 lb gross.
A Sport Trainer gives a buyer a new-built Cub with modern materials, a higher gross weight than a J-3 and the amateur-built privileges of owner maintenance and an A&P condition inspection, at the cost of being whatever its builder made it: the engine, the tanks, the gear (many are on floats or big tyres), the empty weight and the finish are all individual, and a 'Super Cuby' is a different, heavier aeroplane under a similar name. Read the aircraft's own weight-and-balance and look hard at the welding and covering. It flies like a Cub, which is the point, and it insures like a tailwheel homebuilt. No usable asking-price band was found; the one example read was on amphibious floats at $95,500.

- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
