The Junkers CL.I was a ground-attack aircraft developed in Germany during World War I. The prototype flew in the late 1917 and was followed over the next few months by three more development aircraft. After the war, one or two CL.Is were converted for commercial service by enclosing the rear cockpit under a canopy. Seagull's Junkers CL1 G-BUYU 15cc with a wingspan of 1750mm is a new model released this year for anyone looking for a model that's out of the ordinary.
