Have to agree with D ,the G4S RTR is the only spec legal RTR available for club racing ,it conforms to ROAR/EFRA/IFMAR rules.
Does not come with some cheap radio ,it comes with a Futaba system with dual rates,EPA etc.
If you enjoy the car and racing ,the car can be upgraded into full spec comp version with no real hassles.
Only other RTR kit that comes close is the 710 RTR but I think they have been discontinued.
My 2 cents.
