Stinson L-13 (sometimes known as the Grasshopper, like other aircraft of its type) was a US military utility aircraft first flown in 1945. Developed when Stinson was a subsidiary of Consolidated Vultee, rights to it were not included in the 1948 sale of Stinson to Piper. Mass production was therefore undertaken by Convair, which built some 300 of them.
It was a conventional high-wing
tailwheel monoplane used for observation, liaison, and air ambulance duties. Following their military service, some were converted for civil bush flying use, fitting a radial engine by Acme Aircraft Company as the Centaur, while others underwent similar conversions by Caribbean Traders Inc, as the Husky.
