Description

The Great Power GP-38 Gas Engine delivers exceptional reliability and strong performance for a wide range of RC aircraft. With a 38cc displacement and 5 horsepower output, it strikes the perfect balance between power and efficiency — ideal for small to mid-size models that demand precision, smooth throttle response, and dependable operation.

Running smoothly across a broad RPM range of 1400–10,000, the GP-38 is equally at home in relaxed sport flying and high-energy aerobatics. The Walbro HDA-246 carburettor and NGK CM-6 spark plug ensure consistent combustion, easy starts, and efficient fuel delivery.

Built for long-term durability, the GP-38 operates on a 40:1 unleaded gasoline/oil mix, offering smooth, low-vibration performance. Included mufflers reduce noise while maintaining strong exhaust flow. Backed by a 2-year Probuild Aircraft Ltd warranty, the GP-38 combines performance, reliability, and value in one compact package.
