MD550 Piston Engine Indicator Parameters MD550 Piston Engine Application Scenario MD550 Piston Engine Dimensions MD550 Piston Engine Power\Torque\SFC Curves Shahed 136's MD550 piston engine The Shahed 136 drone, which weighs more than 200 kg, uses the MD550 piston engine. The output power of this four cylinder horizontally opposed air-cooled two-stroke engine has reached 50 horsepower, and its deadweight is only 16 kg. The larger and heavier witness - 136 naturally needs a stronger engine. At the same time, the piston engine can also ensure lower fuel consumption, so as to achieve a huge range of 2500 kilometers. According to professional observation, Shahed 136's MD550 piston engine is a counterfeit
