Wag Aero J-3 Cub Replica for Sale — Buy or Sell Homebuilt Piper Cub Replicas
The Wag-Aero J-3 Cub Replica is one of the most beloved homebuilt aircraft kits in American sport aviation history — a faithful reproduction of the iconic Piper J-3 Cub that captures everything pilots love about the original: simple systems, gentle handling, and the pure joy of slow, low flying. Produced by Wag-Aero Group of Lyons, Wisconsin, the Wag-Aero Cub kit was designed for amateur builders who wanted to own a Cub-like experience without the cost or limitations of an original 1940s certificated airframe. Thousands of Wag-Aero Cubs have been completed and flown across the United States and internationally. On Airplane Trade, completed Wag-Aero Cub Replicas are bought and sold through a marketplace that connects homebuilt aviation enthusiasts worldwide.
About Wag-Aero Group and the Cub Replica Kit
Wag-Aero Group became one of America's premier suppliers of homebuilt aircraft plans and kits for Cub-style aircraft, offering both the Sportsman 2+2 (a stretched, two-seat side-by-side design) and the classic Cuby — a faithful tandem two-seat Cub replica. Both designs drew directly from the J-3 Cub's lineage, using similar steel tube fuselage construction, fabric covering, and high-wing monoplane configuration. The kits were made available as plans-built projects or as partial kits with prefabricated components, allowing builders of varying skill levels to complete their aircraft using Wag-Aero's detailed instructions and support documentation. The result was an aircraft that looks, flies, and feels nearly identical to a genuine Piper J-3 Cub.
Design and Construction
The Wag-Aero Cub Replica follows the original J-3 Cub's construction philosophy:
- Welded steel tube fuselage — 4130 chromoly steel with fabric covering (Dacron or Ceconite)
- Wooden wing structure — Spruce spars and ribs, fabric covered, following J-3 dimensions
- High-wing, strut-braced configuration — Classic Cub appearance with excellent low-speed visibility
- Tandem seating — Two occupants in fore-and-aft arrangement, student forward, instructor aft
- Conventional tailwheel gear — Simple, robust, and ideal for grass and sod operations
- Engine options — Continental A-65, A-75, C-85, C-90, or Lycoming O-235/O-290 depending on builder preference and power desired

Flying Qualities
The Wag-Aero Cub Replica flies with the same docile, confidence-inspiring qualities that made the original J-3 Cub the most popular trainer in aviation history. Light stick forces, a wide speed range between stall and cruise, and a forgiving power-off stall make it an ideal aircraft for primary instruction, tailwheel checkout, and relaxed recreational flying. The low cruise speed is a feature, not a limitation — it allows pilots to truly see the landscape below and enjoy the sensory experience of flight that high-performance aircraft cannot provide. Grass field operations, fly-ins, and formation flying with other Cubs are the natural habitat of this aircraft.
Buying a Wag-Aero J-3 Replica: What to Know
As an Experimental/Amateur-Built (E-AB) aircraft, the Wag-Aero Cub Replica operates under FAA Experimental category certification. Key considerations for buyers include:
- Builder's log — Verify the aircraft was built in compliance with the 51% rule and that an FAA airworthiness certificate was properly issued
- Construction quality — Inspect welding quality on the steel tube fuselage, fabric condition, and control system rigging
- Engine documentation — Verify engine logs, time since overhaul, and compliance with applicable ADs
- Annual condition inspection — Experimental aircraft require an annual condition inspection by a certificated A&P or an FAA-authorized repairman
- Operating limitations — Review the aircraft's specific operating limitations document issued with the airworthiness certificate
