Provides approximately 3.5-4.0 horsepower, with an extremely high thrust-to-weight ratio.
Ideally suited for aircraft with a wingspan of 1.8m-2.2m and a weight of 5-7kg.
2.Fuel and Economy:
Uses a mixture of 92-octane or higher unleaded gasoline and dedicated two-stroke engine oil (recommended mixture ratio approximately 40:1 to 50:1).
Operating costs are significantly lower than comparable methanol-fueled engines, resulting in better fuel economy.
3.Structure and Reliability:
Single-cylinder, air-cooled, reed valve intake design; simple and robust structure.
Standard diaphragm carburetor (such as the Waborough WT series), adaptable to various flight attitudes, providing stable fuel supply.
Equipped with CDI electronic ignition, requiring no external power supply, making starting relatively easy.
The main body is made of die-cast aluminum alloy, with key components such as the crankshaft, connecting rod, and piston rings using robust materials to ensure excellent durability.
4.Application Scenarios:
Realistic Aircraft: Ideal for the power needs of WWII fighter planes (P-51, Spitfire, etc.) and classic aerobatic aircraft.
Aerobatic Aircraft: Suitable as a "semi-realistic" training aircraft or small to medium-sized aerobatic aircraft in the 50-60cc class.
Large Trainer Aircraft: An excellent choice for beginners using large gasoline engines.
Typical Technical Specifications
Displacement: 30.5cc
Bore × Stroke: 38mm × 27mm
Output Shaft: Standard M8×1.25 threaded output shaft (compatible with various propeller clips or covers)
Weight: Approx. 1400g (excluding exhaust and ignition)
Recommended Propellers: 18x10, 19x8, 20x6, etc. (selection depends on aircraft type and flight style)
Recommended Speed: Typically 7000 - 8500 rpm (static ground)
