Sling 4
These figures describe a typical build. Each aircraft of this design was built by its owner, and the one you are looking at may differ.
The Sling 4 is the four-seat Sling that preceded the TSi: the Sling 2's all-metal construction stretched for four, a 32.6 ft wing, 1,036 lb empty and 2,028 lb gross on a turbocharged 115 hp Rotax 914 with an Airmaster constant-speed propeller, quoted at 130 knots, a 46-knot stall, 800 fpm and 700 nm.
The Sling 4 is the economical four-seater - 130 knots on about 6 gallons an hour - and its limitation is the 115 hp Rotax 914: 800 fpm at gross is modest with four aboard on a hot day, which is why Sling replaced it with the 141 hp TSi. It is a kit aeroplane, so the builder's work and the weight-and-balance are the record, and the 914's turbocharger, waste-gate and constant-speed prop add maintenance a 912 lacks. The useful load of nearly 1,000 lb is genuine for the class. The owner may maintain it and the condition inspection needs an A&P or the repairman certificate; Sling supports the type from Torrance and Johannesburg, though the kit itself has been superseded.

- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
