Great craftsmanship , ambition , and dedication to their Hobby to make a track so realistic and nice. What I noticed in the video that was impressive to me was how realistic the speed was of their vehicles. It only takes a little bit of imagination and one could swear they were full size vehicles driving through rugged terrain . When I was in Sedona Arizona , we took four wheelers in the outback there and it is amazing what they can do with their full size 4x4s ! They went up and down spots that looked impossible . This setup and the way they drive there RC trucks, remind me of that Outback trip in Arizona .
