O.S. Speed T1204 Touring Engine (OSMG2006)

The OS Speed Touring Engine is a high-performance nitro powerplant designed for on-road RC racing. Building on a world-champion design, it delivers more torque in the low-to-mid range and stronger mid-range power for quick, confident acceleration on the track.

Key features include a crankshaft with two tungsten weights in the counterweight to boost mid-range torque, a cooling head with wider fin pitch for improved cooling efficiency, and a slide-valve carburetor with a 5.5 mm reducer. A turbo glow plug with a medium heat range supports reliable starts and stable idle, making this engine well suited to competitive on-road racing and serious hobby use alike.
