MOPWGT275: The Powerhouse for Advanced UAV Applications
China Moneypro has established a strong reputation for manufacturing high-performance gasoline engines, and the MOPWGT275 twin-cylinder horizontally opposed two-stroke liquid-cooled engine exemplifies their expertise. This engine is specifically engineered by China Moneypro for demanding applications, including unmanned aerial vehicles (UAVs), power umbrellas, and ultra-light experimental aircraft. The MOPWGT275 incorporates several innovative features, such as a novel circulating cooling waterway, a unique idling storage jet device, and a classical yet robust structure. These design elements contribute to low vibration levels, substantial power output, lightweight construction, and extended operational life. The engine provides rapid throttle response, ensuring a smooth and linear power delivery that supplies your aircraft with stable, abundant power for an unparalleled flying experience. It is ideally suited for unmanned helicopters with a take-off weight of 80-90 kg, as well as fixed-wing UAVs weighing up to 200 kg and single-car powered parachutes.
Key Technologies and Innovations in the MOPWGT275
The MOPWGT275 integrates advanced engineering solutions to maximize reliability and efficiency. At its core is a custom-made automatic angle-advancing capacitor discharge dual-cylinder synchronous ignition system (ACDI), which includes a controlled lock function for precise timing. The fully enclosed circulating liquid cooling system, a China Moneypro patented technology, maintains optimal operating temperatures under varying loads. Additional enhancements include a cylinder liner treated with Ni-SiC (providing a life of 500 hours), a precision-forged crankshaft processed with liquid nitrogen for superior strength, CNC-carved needle roller bearing connecting rods, and a self-locking centrifugal mechanical impeller pump for the circulating water system that ensures high reliability. For ease of use, the engine features a one-key electric start and an integrated generator (300W/5000RPM). A honeycomb resonance exhaust muffler effectively reduces noise levels during operation. The engine also uses a single Iridium K6RIU spark plug and high-quality bearings throughout its construction.

Performance and Durability Features
The engine’s features are designed to deliver consistent performance and longevity. Key attributes include the ACDI automatic timing angle capacitor discharge double cylinder synchronous ignition system for optimal spark timing, and the patent circulating liquid cooling system that prevents overheating. The Ni-SiC treatment on the cylinder liner extends its service life significantly. The liquid nitrogen treated, precision forged crankshaft withstands high stress and rotational forces. CNC carved needle roller bearing connecting rods reduce friction and wear, while the self-locking centrifugal mechanical impeller pump ensures reliable coolant circulation. Convenience is enhanced with the one-key electric start and integrated generator providing electrical power. The honeycomb resonance exhaust muffler minimizes operational noise. Each of these elements contributes to an engine that is both powerful and dependable, making the MOPWGT275 a top choice for demanding aviation applications.
