A cooling shroud assembly for an engine is disclosed. This cooling shroud assembly includes a shroud body. There is an inlet door or flap to an interior of this shroud body, along with an outlet door or flap from this shroud body. When installed on an engine that is incorporated by a moving vehicle (e.g., aircraft, unmanned aerial vehicle, radio-controlled aircraft, watercraft), airflow through the shroud body from an inlet to an outlet. The position of the inlet and outlet doors may be adjusted (e.g., simultaneously) to change the airflow through the shroud body, and to thereby change the dissipation of heat from the operating engine via this airflow.
