Ok so I wanted to know everyones thoughts on this. What is the minimum length you think a test track could be? I really don't have the space to keep our scout track up at all times but want to have something good to test on. Would 20' be to short? I know the glide on the straight will not be shown the shorter I go, but where do you think that break point would be, 16', 20' 24' etc?
