That's a cool track for a backyard type. I prefer longer straights so you can get some great speed and air like the one Sky and I use at one of my work sites.
Hmmm, I may even get one of my guys to make a full scale track with the bulldozer. No matter what I do it has to look semi natural so my boss does not see it as a track but as natural ground formations that I run my RC on. Hmmmm the brain it devising a devious way to accomplish this!
