The Harvard was a largely produced trainer during World War II. It was used in Canada and other alllied countries as an advanced trainer. This scheme is a Harvard MkII used as part of the British Common Wealth Air Training Plan. The Harvard (often refered to as its AT-6 twin) featured a Pratt and Whitney R-1340 600hp radial engine which turned a 9' 1" Constant speed propeller. The prop tips often broke the speed of sound, giving the Harvard its distinctive roar. Today many Harvards are still flying as a result of continuous care and maintenance. This harvard is sensitive on the controls, and can stall the tail when pulling hard. The gear is retractable, and the flaps are controlled by VTOL. Trim using keyboard shortcuts. Up is often best. It can be squirrely on take off so be on your toes.
