Sling 4 Turbo Kit – A Dream with 4 Seats

Pure PERFORMANCE | Absolute QUALITY

The Sling 4 Turbo was designed with the aim of creating the most practical and desirable lightweight, 4-place Experimental aircraft on the market, a niche not previously filled. The plane is basically an elongated version of its sibling, the Sling LSA, however it uses the more powerful Rotax 914 Turbo and has Gullwing doors instead of a sliding canopy. It can comfortably seat 4 people, carry baggage and still cruise effortlessly and efficiently, making it the ultimate affordable cross-country aircraft. Her flying characteristics are very similar to the smaller Sling LSA, perfectly-coordinated with highly responsive controls that are not too sensitive! The Sling 4 Turbo is the perfect aircraft for the home builder who is looking for an affordable DIY 4-place airplane. Aluminum construction is used for ease of maintenance and construction as well as its proven strength and lifetime qualities. The Sling 4 Turbo comes with a variety of customization options that the builder can explore as well as the option for a Ballistic Parachute for safety purposes. No single aircraft can fulfill the special needs of every pilot. Nevertheless, The Airplane Factory believes that the Sling 4 Turbo enjoys a set of qualities that will fulfill the needs, at the highest level, of many pilots around the globe.

The Airplane…

Design and Construction

The Airplane Factory is proud to be the producer of high quality, high performance Light Sport and Experimental Aircraft. We take every step to ensure that each aircraft produced, whether ready-to-fly or kit version, is held to the highest of standards, above and beyond that required by ASTM or the FAA. The reason for such meticulous design and construction is because most of us here at The Airplane Factory are pilots. We know and understand the concerns of our fellow aviators and we would never build anything we did not 100% believe in or endorse. Every new design prototype is tested to its ultimate breaking points to ensure maximum reliability and durability, not too mention the extraordinary efforts The Airplane Factory goes to in order to make sure handling and stability are in the upper echelon of all airplanes on the market today. In addition, each kit we produce is inspected and assured to be top quality before being shipped to the buyer. The Airplane Factory founders feel that the Sling airplanes and kits are the best on the market and believe that you will soon agree!

The design was conceived in 2006 as a result of Mike Blyth’s desire for a Light Sport Aircraft (LSA) that had better performance and handling characteristics than anything on the market. This vision would be an airplane capable of acting as either an exciting pleasure craft or a forgiving trainer. Mike decided to go with a stressed skin, riveted design for its proven technology, durability, and ease of construction. He also wanted to make an all-metal, low wing airplane that would have excellent visibility, sporty handling, and a sleek and sexy exterior.

The aluminum he chose was 6061 Aluminum Alloy. To be more specific, 6061-T6 Aluminum, a tempered grade that has been heat-treated and aged to add a significant strength element. The Sling uses all traditional AN Hardware in its construction, meaning it lives up to the US Air Force/Navy Standards. Solid rivets are used on the main spars, which are standard aviation type spars with our own unique design for added strength, and pull rivets for the rest of the structure, making construction a bit easier while maintaining structural integrity. The Airplane Factory uses high quality rivets manufactured in Germany that are well known throughout the aircraft manufacturing industry. Composites are also used throughout the airplane where appropriate, for example, cowling, fairings at the wing roots and the intersection between the vertical stabilizer and the fuselage, wheel pants, as well as the instrument panel and canopy structure. For reduced weight but added strength, the landing gear is also composite construction which can take a heavy amount of stress regularly without issues.

The standard assembly process for each Sling begins with the different aircraft subsections being assembled. After the Empennage, Wings, and Fuselage are ready they are sent off to receive their Primer and Epoxy painting. Concurrently, the engine, electronics and canopy are fitted. When the parts come back from painting the wings and empennage are bolted to the fuselage and tested. Lastly, the fairings are put in place and the aircraft is ready for testing.

Each part of the aircraft manufacturing process has a full set of quality control procedures that The Airplane Factory directors personally oversee. Each part part is carefully inspected and all metal is punched precisely by our CNC machines. The quality assurance managers then inspect the entirety of the shipment before sending out to the buyer.

How to Order

  • Sling Kits can be ordered as a complete kit or as individual kits. The empennage kit is normally the first kit ordered if ordering kit by kit. It is inexpensive, fairly small, quick to build, and the assembly of the tail kit uses the same skills you will use throughout the build. After putting this together over a weekend, you will have a fairly good idea of what you are in for with the rest of the kit!
  • Shipping is quoted on a per shipment basis
