I used to race 1/10th electric indoor back in my teens, had a couple of Schumachers (Cougar and Top Cat) and then an Associated RC10, used to do okay in the BRCA northern leagues but funds were limited for this school boy back in 1992-3 and you needed a good few quid spending every year to stay competitive.
A mate of mine carried on racing (when I found girls and beer) and I think he's rated as one of the best in the UK if I get my facts straight, 1/8th nitro, think he's sponsered by Losi??
I bought a 1/8th Nitro second hand last summer but only had it out once because I felt a bit daft stood on the street with neighbours glaring!!
And I've also got a TT01 tamiya based Subaru in the wardrobe as well (with a 16T motor installed for good measure!), just waiting for my son to grow some more so I can blame him for all my big boys toys but he's only 3 months old yet so I don't think that excuse would wash!
