The HANG-X HX-65 is a high-performance single-cylinder, air-cooled 2-stroke petrol engine designed for RC model aircraft applications. With a manufacturer-rated displacement of 66cc, the HX-65 delivers up to 7HP (5.15kW) at 10,000rpm, making it a powerful option for large-scale fixed-wing model aircraft.

Its compact 1,540g main-engine weight, carburettor control system and recommended propeller options of 23×10, 24×9 and 24×10 make the HX-65 well suited to pilots looking for a strong power-to-weight combination for demanding RC aircraft builds.

The engine features a 48mm × 37mm bore and stroke, 9.3:1 compression ratio, air cooling and a 6V–14.4V ignition system. The manufacturer specifies a 45:1 fuel-to-2-stroke-oil ratio using FD 2T oil.
