The Stinson L-13 (sometimes known as the Grasshopper) was a conventional high-wing tailwheel monoplane used for observation, liaison, and air ambulance duties 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 302 of them.
A 2-3 seat liaison and ambulance aircraft built for the USAF, power was a 245 h.p. Franklin O-425-9 engine. The L-13 has folding wings, interchangeable wheel, float or ski undercarriage, and can be towed as a glider. Two stretchers can be carried, as well as the pilot and medical attendant.
The United States Army received 43 ex-Air Force L-13As following the outbreak of the Korean War, serving in the Continental United States to free up aircraft for active service overseas. Some were still operated in 1955.
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.

TheAcme Aircraft Centaur 101 and 102 circa 1953 were six-place conversions of surplus Stinson/Convair L-13A for bush flying, based on a prototype by Longren Aircraft Co, Torrance CA (N4901V). The Centaur 101 had a 300hp Lycoming R-680-E3, and Centaur 102 with 300hp Jacobs R-755-A2. Reportedly only a few were converted.
