Wipaire is most often known as being the leading designer and manufacturer of Wipline floats. In reality, Wipaire has been engineering and building the highest performing and most popular aircraft modifications since 1960. While your Twin Otter is visiting Wipaire why not have a few upgrades too!

-34 Engine/750 HP Land & Seaplane

If you are looking for a better performance for your DHC-6-300, look no further. Wipaire has Pratt & Whitney PT6A-34 engines approved for the 300 series Twin Otter at 750 hp for both the floatplane and landplane. Takeoff and climb performance are greatly enhanced for a much broader operational envelope, particularly when operating on amphibious floats or straight floats. The additional 130 hp in each engine allows for shorter runway requirements and optimum climb capability when in restricted terrain.
