Reds Racing has released a new version of 721 Scuderia PRO Gen 3 3.5cc Offroad engine.  The latest version features a completely redesigned cooling head for a lower gravity centre, improved aerodynamics for a lower drag and improved engine cooling. Internally it gets new double seal front bearing for increased durability and idle stability and a new rear ceramic bearing for increased durability and reliability.  The new 721 Scuderia Pro Gen3 is a high torque engine which has specifically been developed to noticeably reduce fuel consumption allowing drivers to get a higher runtime compared to other engines on the market. It features Long Stroke geometry 16.2×16.9 mm, 7 scavenger ports and a single exhaust port cylinder sleeve that works with the crankcase to deliver more low-to middle-range torque.  The engine has been designed to develop an incredible wide RPM range of usable torque. It comes with a DLC Coated crankshaft and backplate for improved engine durability.  The crankshaft can last approximately 3 times more than a conventional steel crankshaft thanks to the extreme hardness of the diamond coating.  Even the conrod life is lengthened by about 50%.
