A flight-test investigation has been made on the Langley control-line facility to determine the longitudinal stability and control characteristics of a model of a propeller-driven tail- sitter-type vertical-take-off airplane with delta wing during rapid transitions from hovering flight to forward flight and back to hovering. The control-line facility provides for the flying of models in a large-diameter circle by means of a control-line technique similar to that used by model-airplane enthusiasts.
