AirVenture Spotlight: Sling It!

3
The Sling High Wing prototype leads the first High Wing taildragger off the taxiway after nearly 70 hours of flying from South Africa.

Keen to show off their new High-Wing variation of the well-regarded low-wing TSi, South African airframer Sling has done so in spectacular fashion by flying the prototype and production serial numbers one and two from Johannesburg, South Africa, to Oshkosh, Wisconsin. The trio landed at AirVenture yesterday afternoon.

Serial number 2 Sling High Wing is this taildragger. The strut-less wing, composite center-fuselage bodywork and extensive flush riveting make the design more slippery than most.
An effusive James Pittman of Sling used a marking pen to describe some wildly small but vertical geography sighted during the Joburg-Oshkosh flight.

The epic jaunt was flown in daylight in legs up the west African coast to the Cape Verde Islands, then the big jump westward across the mid-Atlantic to the Barbados, Bahamas, Florida and finally Oshkosh. The trio arrived to a hugely exuberant contingent of family, friends, the crew from the Sling Aircraft booth plus a phalanx of photographers and reporters.

While the official statistics will come soon enough, the first look at the numbers say the trip took 67.5 flying hours over 10 days. Fuel burn from the Rotax 915iS engines was guesstimated as between 29 and 35 liters per hour—in the 7 to 9 gph range—at 140 knot airspeeds. Winds were favorable over most of the route, save for 25 knot headwinds in the middle of the U.S. leg.

Linda Sollars, Matt “Bulldog” Cohen, J.P. Schultz and James Pittman celebrate their “Joburg to Oshkosh” flight.

No issues were encountered on the flight and the crews said they were often ready for more flying. They were certainly energetic in their enthusiasm upon their AirVenture arrival.

Plans for the three aircraft vary. The prototype will return to South Africa while the two N-numbered production aircraft, which were flown by their owner/builders on the hemispheric-trotting ferry flight, will remain in the U.S.

The Joburg-Oshkosh adventure was just the latest of long-distance Sling flights. As this map on the prototype High Wing shows, flights from South Africa to Madagascar, Belgium, Poland, an earlier Oshkosh flight and two round the world flights are already in the books.

  1. I like the 3 blade propeller. And the tail dragged version. And no wing strut. Composite and the rivet configuration is also a plus. Is this a constant speed propeller, and does it have extended range fuel tanks? If so, it would be quite the airplane to fly. Especially in a high horse power application.

  2. From their web site, STANDARD fuel tanks offer 8 hours endurance & 880nm range, bladder busting long range tanks are available too! CS prop? Yes.

  3. Wow! What an adventure flight! Putting the faith in the Rotax. It’s sure becoming the small Continentals and Lycs of the time. Hate to not prop another A65, but a fellows’ got to move on.
