The Rainbow Aerotrike is a family of South African two-seat ultralight trikes, made by Rainbow Aircraft of Edenvale, Gauteng and available in kit form for amateur construction or fully assembled. The type has been noted for its long-distance flights.^[1]^[2]^[3]^[4]^[5]^[6]

Design and development

The current Aerotrike series comprises two variants of the same basic design, the Scout and Cobra. Both share the same basic design, including the two-seat carriage frame, suspension, steering and folding inverted "V" mast assembly. The Scout is equipped minimally, while the Cobra has many options as standard equipment, including a cockpit pod fairing, windshield, instrument panel, saddle bags and wheel pants.^[1]^[6]

Both models require 30–40 hours to assemble from the supplied kit.^[1]

Operational history

The Aerotrike series were the choice of Mike Blyth for his record long-distance flights. The first in 1995 was from Cape Town, South Africa to North Cape, Norway a distance of 10,255 mi (16,504 km) and the second was an around-the-world flight of 29,000 mi (46,671 km).^[1]^[2]^[3]
