TL01LA's are the ones to have over here, that suspension kit is over £50 to buy alone!
I tried a F103 a couple of years back, a friend of mine was selling all his stuff and let me borrow it as a kind of mobile advert.......even though it was tarmac, and very warm, it was very slippery. Might have been down to the 12x2 Trinity motor it had!
My brother used a Protoform TVR, he didn't like it either. He likes a well tied down car, and it just used to drift through the corners. He thought that all it needed was a wing which was a bit bigger.
I have an Associated RC12 L3 now, I swapped a RTR Tamiya M03 Mini for the L3 rolling chassis. Just need some Yokomo battery straps and a decent ESC to run.
