REDS Racing is excited to introduce a new S Line nitro off-road engine. 721 Corsa engine is a 3.5cc 7 ports engine based on S Line 721 Scuderia engine. Our main objective was to release a new engine similar to 721 Scuderia at a reasonable price.
Both engines feature high reliability, tuning stability and great fuel mileage. REDS Racing’s new generation engines are produced with different materials, from different suppliers and with new technologies. All assembled in-house. S line engines feature new materials for piston, sleeve and crankcase in order to optimize thermal expansion and improve power.
