Thanks guys. I think I'd want 4wd having watched some videos. I do like the volition but as mentioned it's 2wd. I'd be using the sct in my back garden which I'd grass and gravel.
I'm quite mechanically competent and understand drive shafts, diffs etc as I work on my own cars quite a lot.
I really fancied a scale rock crawler but the high price put me off as I first start into the hobby.
I like the idea of up grades, brushless motors, upgraded esc, batteries etc.
I'll keep my eye out on ebay and on here for used 4wd sct too.
Many thanks for your input, it's really helpful.
