A system includes a fabric wing, such as a Rogallo wing or parafoil, a roller connected to the fabric wing, cables connected to the fabric wing, a motor connected to the roller. Upon activation, the motor causes the roller to roll-up or unroll at least a portion of the fabric wing. The system may include a rigid or collapsible roller support structure connected to the roller. The roller may be located along a central axis of the fabric wing. A control unit may be connected to the cables, the control unit including a logic controller, power source, communications system, GPS and inertial navigation sensor system, motor controller, and one or more sensors including an air speed sensor, altitude sensor, obstacle detection sensor, and/or a ground proximity sensor. The system may include a second roller with an attached motor, with each roller located at an end of the fabric wing.
