Building a RC track
 

Hello everryone and let me say first that if this is in the wrong forum, just let me know I will move it.

My 9 and 13 year old sons have been playing with RC for a while now and both have been after me to build a track in my back yard. I have about a spot that is about 50 ft long and as wide as I want it that is away from any of my wife's projects. I was wondering what size would be a minimun for running 1/8 scale cars on it. There may be at the most 4 or 5 cars on the track at a time. I have an idea of the design, I just want to make sure I have the demisions right so it is enjoyable driving.

Thanks,

Walkin
