Brand New in box, never used or run. Manufacture Description below: The Turnigy TR-55 engine packs a 5.6HP punch and includes an all machined billet alloy crank, high-power reed valves and porting for high torque! The machined billet aluminum case is strong, and lightweight, that combined with the power it puts out makes the TR-55 perfect for your 50-55CC class 3D and Aerobatic airplanes. Since the TR-55 runs on regular pump gas, operational costs are low, and the fun factor high.
Features: • Billet aluminum case with sand cast cylinder heads • CDI electronic ignition • Includes compact muffler
