I'm having trouble deciding on which one to get as far as bang for buck. I have a notorious I've extended and upgraded and wanting something more or different. I've never had a 1/5 scale so I'm not really sure if it's worth having or if I should stick to 1/8th scale. I'm still kind of a beginner and will be building a track in my back yard. Probably like a bmx style for jumps flips and such. Thanks for any advice
