Rand KR-2S

TerryLeave a comment

The KR-2S includes a 16 inch stretch in the fuselage over the standard KR-2, 3 inches more head and leg room and pre-molds made of the latest oven-cured, vacuum-bagged pre-pregs. Its raked canopy and fixed landing gear give it a racy appearance and the KR-2S will accommodate engines including VW’s, Subaru derivatives, Continental C-85’s, and O-200’s.

Rand KR-2

TerryLeave a comment

The KR-2 is a two-place version of the KR-1 and is generally similar in construction. The low wings are removable, the main gear is retractable and the tailwheel is steerable. With a stock 1600-cc engine, cruise speed is 140 mph. With a 2100-cc turbocharged VW conversion, cruise is 180 mph at 3200 rpm. To achieve simplicity of construction, the airplane is designed so that no machining or welding is required in building the airframe. The cost and construction time is minimized by using a combination of wood, polyurethane foam, fiberglass cloth and epoxy resin. The result is a structurally strong, clean, hard surface and an exceptionally fast airplane for the power used. All new premolded fiberglass parts have been developed to speed the building time for the KR-2. Luxury upholstery kits are also available and can be simply snapped into position.

First flown in July 1974.

Ken Rand, in 1974, commenced marketing plans and kits for the single seat KR-1 and two-place KR-2. Instant acceptance saw 9000 plans and kitsets sold within the first five years.

As with all KR’s, the KR-2 is equipped with removable wings, and choice of retractable, fixed conventional, or tricycle gear.

Rand KR-1B

TerryLeave a comment

The KR-1B motorglider is essentially a stock KR-1 with longer wings and a bigger tail. For a wing curve, an RAF-48 standard KR-1 airfoil was used for the center section and the GA(W)-2 airfoil for the replacement outer panels. The outer wing section provides a clean and responsive curve for use with a spoiler/flap control, permitting deadstick landings at 70 mph TAS. Where the stock KR-1 wingspan is 172″, the motorglider wingspan measures 27′ from tip to tip, thereby increasing square footage from 64 to 91.

Power is supplied by a 60-hp VW engine. Maximum cruise is 130 mph, and with 33 gallons of fuel, range is 950 miles while getting 29 mpg. At the standard 4-gph burn rate, 33 gallons should deliver 8.25 hours of flying at 120 mph for a range of 1,020 miles.

Rand KR-1

TerryLeave a comment

Ken designed the KR-1 in 1972 using cutting edge building techniques that would later become the standard for modern aviation.

Rand KR-1 Article

The KR-1 is the single seat low wing retractable monoplane which is typically powered by smaller VW engines, up to the VW 2100. The KR-1B motorglider is a standard KR-1 with modified outer wing sections. With this simple wing conversion, the original KR-1 becomes an excellent self-powered glider.

Ken Rand, in 1974, commenced marketing plans and kits for the single seat KR-1 and two-place KR-2. Utilising spruce, foam and Dynal cloth in construction, these designs could be built in as few as 800 hours sparetime work. The clean lines and smooth finishes attainable with this technique meant reduced drag, resulting in higher speeds on less power. Retractable gear adds to its performance. The prototype KR 1 (first flown in February 1972) reached 150 mph in level flight, powered by a 36 hp converted VW car engine. Instant acceptance saw 9000 plans and kitsets sold within the first five years.

On September 7th, 2009 Jeanette Rand, President of Rand Robinson Engineering, officially announced that nV Aerospace will be the exclusive Manufacturer and Distributor for the KR line of aircraft and related components.
Rand Robinson retained the rights to the design but all inventory and tooling was acquired by nV|Aero to produce the KR kits. Plans for a fast build fuselage, improved wing and empennage airfoils and several other design improvements are under way.

Rainbow Ranger

TerryLeave a comment

New in 2002 was the Ranger I from Rainbow Aviation. This design evolved from joining a Continental 65 hp engine to an ultralight wing and a Breezy airframe.

The landing gear is formed from the composite spring used in a Pontiac Trans Am. The wing and tail are all metal and the fuselage can be fabric covered if desired.

RagWing RW26 Special II

TerryLeave a comment

Qualifies as an LSA. The “Special II” can be built as a legal ultralight trainer or with a larger engine, as an experimental. The “Special II” basic kit will be an all-wood kit, like the single seat, to keep the pricing affordable. These kits are fairly fast to build. The kit was planned to be available in a steel tube version.
