I really don't know anymore ! Apparently the LED box is only for the Stock version, but it is on the Speed Passion Reventon S page & also describes loads of things it will do ! I got hold of a LCD box last night so will give that a go. RCMart have offered me a refund but I want to give it one last try. These toy cars are a lot of hassle !
