Al, I think your track is great use of the space you have. I definitely understand the desire to have the lane lengths pretty close, in theory this should provide the closest racing.
I was simply thinking of a larger simple layout because I have a large 2 car garage that I never have cars in. (all my toys sit at my shop). Plus I was thinking that this would reduce the complexity of building it for my first track.
I would like to have it up against the wall, so I think only going 4' deep is probably the best bet, but I could have an "L" layout something like 20 long and 4 on the short side....I think.
How much track feet are you guys running before doing power taps?
