The Roe IV Triplane was an early British aircraft. It was an all-new design by Alliott Verdon Roe for A.V. Roe and Company and reflected the basic aircraft configuration that was to become the convention. With this design Roe returned to wing warping as a means of control. The single example built was used for a while as a trainer at the Avro Flying School at Brooklands Surrey.
