The radio-control (R/C) model is being developed as a tool for spin research of general aviation airplanes. This paper discusses the construction, instrumentation, and tests of a 1/6 scale radio-control model of the Beech YT-34C. Spin test results are compared for the R/C model, spin tunnel model, and full-scale airplane. Possible explanations for differences in spin characteristics are discussed. Future R/C model test plans are outlined.
