The Great Power GP-88 is a high-performance 88cc single-cylinder gas engine engineered for serious giant-scale RC aircraft pilots demanding exceptional power, reliability, and lightweight performance. Producing an impressive 10 horsepower while maintaining an ultra-light overall weight of just 1980g, the GP-88 delivers outstanding power-to-weight efficiency for 33%–35% aerobatic aircraft and large-scale 2.5m–3.3m warbirds and scale models. Designed with a dynamically balanced crankshaft and piston assembly, the GP-88 significantly reduces vibration despite its large-capacity single-cylinder design.

Supplied complete with ignition system and Pitts mufflers, the GP-88 provides everything required for installation straight out of the box. Featuring a proven Walbro WJ-71 carburettor, NGK CM-6 spark plug compatibility, and excellent throttle response, this engine delivers dependable performance across the full RPM range. Despite its compact and lightweight design, the GP-88 produces power levels comparable to many larger 100–110cc engines, making it one of the most efficient giant-scale petrol engines available today.
