With the success of the DHC-2 Beaver, DeHavilland Canada sought to expand their foothold into the Bushplane market by offering an aircraft with increased size and load capacity. This became the Otter. On floats, skis, or wheels, the Otter is truly a great bushplane.
All of the Otters built between 1951 and 1967 were powered by an Pratt & Whitney Wasp [R-1340] 600 HP engine. The Wasp production ceased in 1960, so replacement engines were sought out, as surplus engines waned. Most of the Otters that are still in service have been refitted with turboprop engines including Pratt & Whitney Canada’s PT6A, Walter 601, and Garrett TPE331. These engines produce between 750 to 1000 horsepower.
This model depicts an Otter that was flying for the US Army in Vietnam. 55-3277 was the manufacturers serial number 124, and served with the 54th Utility Airplane Company. Ultimately it was turned over to the Cambodian Government where is was scrapped.
With three pages of parts and photographic step-by-step instructions this model is rated at 2/5 for build difficulty.
