Description

/// CAPTURE BONUS DEPRECIATION ///


/// PURE FUN, TOTAL FREEDOM ///


Mason Amelia presents N401SQ, an aircraft that puts FUN and FREEDOM in the same package.


Built to exacting standards of quality and craftsmanship, the SQ-12 is the culmination of 25 years of experimental Cub building, starting with the famed Wayne Mackey and the SQ-1. Every subsequent iteration incorporated new designs and materials, striving to increase performance and build the perfect backcountry aircraft. 


A true STOL aircraft built to haul, the SQ-12 outperforms all other Cubs. An all-time favorite of Alaskan pilots, load it with supplies, take off in 100 feet, land in 100 feet on a mountaintop or gravel bed. No other Cub comes close to its performance, nor its attitude.


Built over 3000 hours with onsite supervision by Wayne Mackey himself, the gray-black carbon scheme is NOT A WRAP. It is miles of fabric tape and 1100 hours of labor. Photos cannot convey the true luster and presence of the aircraft, nor the PURE PILOTING ENVIRONMENT  of its sport-luxury cabin.

 

Built in Alaska for true adventure, winner of the 2025 Outstanding Workmanship award at EAA AirVenture, N401SQ is a step beyond. Meant for the serious backcountry pilot, this is THE connoisseur’s Cub, the best of the best. Not a toy, a true performer - built to offer opportunities few get to experience.
