# Rainbow Aerotrike

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.

## 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.
Both models require 30–40 hours to assemble from the supplied kit.

## Operational history
