Not a real ED Transmission System actually since real ED is made by 7075-T6 alloy......... but all new G4s (RS, JS, JR) have same design scheme and gear ratio as ED system.
Quick to get your G4RS built and have fun. Our US racing team have a full test on G4RS (3 cars) last week, running very good and they will participate "Byron's challenge 2008" this weekend.
