dc.description.abstract	Wind-tunnel tests were needed to obtain aerodynamic data on the Shetland. The following measurements were made: 1. Lift, drag and pitching moment for various conditions of the model over the complete flight range, with flaps up and down. 2. Directional and lateral stability. 3. Ele+ator, rudder and aileron effectiveness. 4. Effect of return-flow nacelles on lift and pitching moment. The lift and drag increments due to the flaps suggest that their design is satisfactory, and no modifications have been recommended. There is a sufficient margin of stick-fixed longitndinal stability without slipstream at normal speeds, but with flaps up there is a loss in stability near the stall. With flaps down there are appreciable changes in longitudinal stability and trim.	en_US
