Sling TSi Kit – Speed on Rails



4 PEOPLE AT 155+ KTAS AT 9,500’MSL!

The Sling TSi Kit is the airplane Sling fans have been waiting for. All of the style, economy and practical utility of the Sling 4, but with more SPEED! Harnessing the power of the Rotax 915iS or the all new Rotax 916iS turbo-charged, fuel-injected and FADEC engine, the Sling TSi maintains the quiet, comfortable and smooth ride with an extra dose of horsepower.


The Sling TSi features an all-new high speed wing design: optimized for the power and weight of the aircraft. The leading edge of the wing is flush-riveted for low drag. The forward fuselage and empennage are also flush-riveted. The landing gear is airfoiled, low-drag wheel pants incorporated and there is a new cowling design.


The interior, seating, ventilation and heatingare improved for passenger comfortand luxury.

Sling TSi and Sling 4 Differences

Although the Sling TSi shares a similar appearance and the distinctive “Sling attitude” with the Sling 4, it only shares about 20% parts in common. It is a completely new aircraft, with different design goals than the Sling 4. The main result of these changes is SPEED.

The Rotax 915iS engine installed in the Sling TSi produces a full 40% more power than the Rotax 914UL Turbo used in the Sling 4. Moving up to the Rotax 916iS engine produces 60% more power at 160HP! This results in impressive climb rates and even more impressive cruise speed exceeding 155KTAS at 9,500′. Both the 915iS and 916iS engines are turbo-charged (with inter-cooler) and fully FADEC-controlled.

The Sling TSi wing is a completely new design compared to the Sling 4. It has a shorter span and a completely new lower profile airfoil designed for higher speed.

For lower drag (and higher cruise speed), the Sling TSi features countersunk (flush) riveting on the following surfaces:

Wing front third leading edge and undersurface
Forward fuselage areas and empennage

The TSi has more streamlined and aerodynamic canopy, airfoiled main gear legs, cowling and wheel pants. All for more speed.

The vertical stabilizer fairing has a new design.

The Sling TSi features upgraded interior appointments and leather seating as well as a larger dash with more instrument panel space without sacrificing any forward visibility.

The TSi has a new powered ventilation and heating system design for more effective heating and cooling.

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 to 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 original Sling 2 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.

For factory-built Slings the standard assembly process 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.

Sling TSi Videos


The Sling TSi’s flying characteristics make for a perfectly coordinated, highly responsive control harmony. This gives her the distinct qualities of a fighter jet aircraft, while not being overly sensitive. Comfortable for the whole family, the Sling is a Pilot’s Airplane. You fly it for the love of it. The TSi is stable, on rails, but has an exciting roll rate.


Ramp appeal. You want your airplane to look as good as it flies. The Sling TSi has strong, sexy, aggressive lines. You’ll feel proud stepping out of it. A more grown-up and bold brother to the Sling 4 Turbo.

Glass Cockpit

The Sling TSi’s avionics options make for a very unique, state-of-the-art flying experience at a fraction of the cost of our certified competitors. Full integrated EFIS with autopilot, radio and transponder with 2020-compliant ADS-B is available with live weather and traffic alerts in the cockpit. No more flying blind.

Gullwing Doors

The Sling TSi’s Gullwing doors make for easy ingress and egress for all 4 occupants. The wide cockpit, excellent all around view and substantial luggage capacity make the Sling TSi a very comfortable, yet versatile aircraft.

Spacious Cabin for 4

The Sling TSi has a spacious cabin for 4 people. With ample knee-room in the back seats there is a feeling of roominess in the cabin. The Sling TSi has as much cabin space as many much-larger aircraft.


The sturdy construction of the Sling TSi make it an aircraft able to go the distance, reliably. The incorporation, by design, of a ballistic parachute (optional) makes the Sling an exceptionally safe aircraft to fly. The use of high quality components throughout gives you, the owner, the peace of mind that you deserve when making this kind of investment.

Turbo Intercooled FADEC Performance

The Sling TSi’s turbo-intercooled FADEC Rotax 915iS or 916iS engine, combined with the new large-chord Airmaster Electric Constant Speed Prop or MT Hydraulic Constant Speed Prop, provides outstanding performance. At max gross weight, with 4 adults onboard and full fuel, the Sling TSi climbs at 1,000 fpm. It maintains a solid indicated airspeed up to altitude resulting in cruise performance of 155 KTAS+

Turbo means that the performance keeps on coming at altitude. FADEC means the engine will always be running at optimum power and efficiency.


With an operating cost of around $60/hr and burning just 7-8GPH of car gas, the Sling TSi is the fast, efficient, economical cruiser of the modern age.

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
