The most powerful FX engine yet! The 160FX is the largest in the popular FX line of aircraft engines, but still boasts many performance features in the traditional short, compact FX design that accommodates tight installations. This power plant comes with a remote needle that can be mounted three ways: vertical, horizontal, and separate from the engine. It's engineered for low fuel consumption, with a wide, wing-shaped exhaust port that contributes to higher torque at lower rpm.
