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.
