The Sling 4 Is Joy in a Kit

Gemini Sparkle

Key Takeaways:

  • The Sling 4 is a unique four-place experimental aircraft that effectively balances a 1,000-pound useful load, impressive fuel efficiency (under 6 gph using mogas), and comfortable amenities at an affordable price compared to comparable certified planes.
  • It delivers strong performance with its turbocharged Rotax engine, offering a decent 125-knot cruise speed and excellent handling characteristics inherited from its two-seat predecessor, the Sling 2.
  • Marketed primarily as a kit aircraft (with options for quick-build and builder-assisted "turbo-build" programs), the Sling 4 fills a niche for pilots seeking an economical, modern, and versatile personal airplane that prioritizes efficiency and payload over outright speed.

“And now for something completely different.” It was a line from that brilliant 1970s British television comedy show, Monty Python’s Flying Circus, but it could just as easily be used to introduce The Airplane Factory’s new, fits-into-its-own-niche airplane, the cheeky Sling 4.
