Rotax's 'Mighty Mite' Remains One Of The Best Bets In Sport Or General Aviation

At the US Sport Aviation Expo, Aero-TV caught up with an old friend, Eric Tucker... a guy who is known worldwide as "Mr. Rotax." The most well-known (and easily the hardest working) expert on the Rotax 900 series sport and certified engines, Eric took a few minutes to help us profile each of the amazingly compact, powerful and fuel-efficient 900 series engines starting with our personal favorite... the 115 HP Turbocharged Rotax 914.

With a dry weight of 141 pounds, the Rotax 914 UL DCDI 115HP engine is a 4-stroke turbocharged engine specially developed for recreational aircraft. It also exists in a certified version as the Rotax 914 F, that received its first cert in 1996.
