MID-HIGH GRIP TRACKS
ENERGY EFFICIENT
HIGH TORQUE
EXTREME TOP SPEED
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.
" The 721 S Corsa has proved to guarantee over 10 minutes runtime in recent competitions and tests thanks to new materials. During testing we found the new engine is able to provide 10% more torque, making it suitable for both Buggy and Truggy"

NEW GENERATION ENGINE
The new 721 S Corsa features high reliability, tuning stability and great fuel mileage. Combined with specific technical changes in the porting and new materials, this 7 port engine features higher power and great efficiency.
NEW MATERIALS
REDS Racing’s new generation engines are produced with different materials, from different suppliers and with new technologies. All assembled in-house. 721 Corsa features new materials for piston, sleeve and crankcase in order to optimize thermal expansion and improve power. The idea was to develop a high power engine even more powerful than WRX and WR7 engines with exceptional fuel mileage. We have achieved it.
NEW CRANKASE DESIGN
REDS Racing S line features a new and unique high stiffness crankcase design. It is all new materials and casting technology. The engine is produced with pressure die casting, this is a very high quality process. Previous generation R line crankcase was with gravity casting.
HANDMADE, TUNED AND ASSEMBLED
The new engine is hand-tuned with a silicone-filled, balanced and tuned crankshaft by M. Rossi. Every single engine is hand inspected and compression checked inside REDS Racing headquarters by Mario and Marco Rossi to achieve the highest quality standards. This is core to the values that makes Reds Racing engines different from any other brand on the market.
