STEWART “S-51D”€

Gemini Sparkle

Key Takeaways:

  • The S-51D is a reduced-scale, highly accurate P-51D homebuilt aircraft, developed over 25 years by aeronautical engineer Jim Stewart to replicate the original in looks, structure, and performance.
  • It features an all-aluminum airframe with hydro-formed panels, ensuring distortion-free curves and high precision.
  • The aircraft is available as a kit in various packages, including a fast-build option, designed to reduce the required construction time for homebuilders.
  • Powered by a 300-600 hp liquid-cooled automotive V-8 engine, the S-51D boasts high performance with a top speed of 265 mph and a cruise speed of 235 mph.

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.
