Rand Robinson Engineering KR-2S
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 KR-2S is the stretched version of the Rand Robinson KR-2, Ken Rand's two-seat wood-and-foam Volkswagen-powered plans design of 1974: 16 inches more fuselage, 2.5 feet more span, a taller canopy and composite-sandwich construction on a supercritical aerofoil, for Jabiru engines of 85-120 hp or a Volkswagen conversion; about a hundred had flown by 2011.
The S fixes the original KR-2's two complaints - a cockpit too small for average adults and a wing too small for its weight - and keeps everything else, which means a plans-built aeroplane of spruce, foam and fibreglass whose structural quality is entirely its builder's and whose figures are unpublished here; the aircraft's own weight-and-balance and test data are the only numbers. Engine choice sets the character: a Jabiru 3300 KR-2S is a 150-knot aeroplane, a VW example much slower, and the VW conversions have no certified parts chain. Wood and composite structure wants a dry hangar and an inspector who knows both. The owner may maintain it and the condition inspection needs an A&P or the repairman certificate; plans and parts come from nVAero.

- Support: class median 77.5.
- Liquidity: class median 20.
- 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.
