The Kitfox Speedster Series 7 by Denny Kitfox is a single engine, 2 seater, amateur built kit plane. The speedster variant of the Kitfox Series 7 line up is much like the Speedster Series 4, but with shorter wings and a faster roll rate compared to other Kitfox aircraft, to increase speed and roll rate. The Kitfox brand has a reputation for making high performance aircraft, capable of extremely short landings and takeoffs, which is excellent for bush flying. Kitfox offers a series of engines to be implemented into their aircraft, all made by the Austrian company Rotax. This addon features the Rotax 912 iS, a four-stroke piston engine, with the capability of producing up to 100 horsepower. This engine is paired with an Airmaster Propeller. These propellers come with a controller system, to change the angle of the blade. This controller has been implemented in this addon.
