I'm about 80% done with my backyard track-- a nice figure 8 with a few small jumps, irregular curves and (purposely) not-so-strait errr....strait-aways.... all we need to do is put in the landscaping and its done....
....but now I've seen this http://www.youtube.com/watch?v=T6aiw...eature=related and rethinking the whole design...
Nice! Are those cars brushed? They're really slow. The trx rallys will need some modding for that
I noticed guys doing Rally run a bit slower- but have much better control of the car... unlike the local indoor track where there is a lot of rail riding....and those are pretty narrow lanes
