STEWART “S-51D”€

Gemini Sparkle

Key Takeaways:

  • The S-51D is a highly accurate, reduced-scale homebuilt replica of the P-51D, developed by aeronautical engineer Jim Stewart over 25 years.
  • It features an all-aluminum airframe with hydro-formed panels, meticulously designed to replicate the original aircraft's looks, structure, and performance.
  • Marketed as a kit, the S-51D is available in various packages to accommodate different builder needs, with the basic kit requiring approximately 3,500 hours of work.

The S-51D is the culmination of over 25 years in development. Jim Stewart’s dream was to develop the most accurate reduced-scale P-51D to hit the homebuilt circuit. Many times the project was put on hold due to many obstacles that producing an aircraft of this type can throw at you. Stewart, an aeronautical engineer by trade, made great strides to make the S-51 as close to the real thing in looks, structure, and performance as possible. Stewart chose aluminum for the entire airframe. Stewart also quickly realized that a kit was required to market the aircraft because very few homebuilders had the tools or the talent to form all of the compound-curved panels. All of the panels in the kit are hydro-formed to obtain the distortion-free curves that make this kit a successful endeavor. Kits are available in a variety of packages to save time and/or money for the builder. The basic kit requires about 3,500 hours of work, and a fast-build kit reduces the required time by about 1,200 hours.
