CubCrafters Carbon Cub EX-3 for Sale — Builder-Assist Backcountry Performance
The CubCrafters Carbon Cub EX-3 is the experimental-category sibling of the factory-built FX3 — offering the same extraordinary Carbon Cub performance package through the Experimental Amateur-Built certification pathway that allows greater flexibility in equipment and avionics choices while delivering identical flight performance to the certified FX3. The EX-3 appeals to buyers who want to personalize their aircraft beyond what factory-built certification allows, who want to take advantage of the builder-assist program to understand their aircraft thoroughly, or who simply want equivalent Carbon Cub performance at a lower acquisition price through the experimental route.
EX-3 vs FX3 — Understanding the Difference
The Carbon Cub EX-3 uses the same CubCrafters carbon fiber fuselage, wings, and structural components as the FX3, and is powered by the same CubCrafters CC393i engine producing 180 horsepower. The difference is regulatory: the EX-3 is built under the experimental amateur-built rules (typically using CubCrafters' builder-assist program where the buyer completes a meaningful portion of the assembly), while the FX3 is factory-built to LSA production standards. Both deliver the same exceptional short-field and backcountry performance that makes the Carbon Cub family uniquely capable.
