Hi new to this forum but have a question. I have room and more importantly permission from the wife to build a dirt oval in the back yard. The scale I have room for is 1/18th. To include the Hpi Micro, brp cars, mini T, Mini Inferno etc...
My question is how much room and the proper dimensions. Also what kind of dirt will give me the best results of duplicating some saturday night shorttrack shootouts. How much banking in the corners how wide etccc.

Thanks in advance
