Thanks for the info chaps! (I also discovered girls back then so the RC got put in the wardrobe, I also quickly discovered girls were alot more expensive to maintain than the RC car, but alot of fun!)
I'v taken the advice and cancelled the 5.5 motor, the only next option they stocked in the MMM series was the 10.5 so gone for that. I hope it wont be slow??? Does iit equate to half the speed of a 5.5, or 2 thirds the speed of an 8.5? (Sorry if thats a bimbo question!) Although being honest and being a noob a milkfloat will probably seem fast to me at first!
Thanks again
Dave
