The 280FX Piston Engine... Feel the Power. Let's talk power. The 280FX has it in abundance. That means hot and high operations are well within an Enstrom's capabilities. The 280FX is powered by a Textron Lycoming HIO-360-F1AD piston engine which is specially strengthened to handle the addition of the turbo-charger. The resulting system provides a full 225 horsepower all the way up to 12,000 feet. Hear the Quiet Power.
