With the dNano, we have a very promising car that is way over its scale MPH in relationship of its scale size; thus special attention needs to be given to the running surface, CG/weight distribution and tires.

As I have some money tied up in this project, you can be assured that I want to get it right; my main goal is to find a roll-up surface that works well for our in-school racing leagues, for which the dNano is perfectly sized.

15-20 minute setup/tear-down (max) is the main design goal, with a forgiving surface that grips well. I expect this project to take the better part of June.

I'm also going to do some work with foam tires on less grippy surfaces to see how the dNaNo performs; I think foam is overlooked and will solve many of the grip problems cited in earlier threads. Banked corners will also help on less grippy surfaces and adds an additional speed/skill/realism element to a small track. And if I have time, drifting, although my driving skills may not be up to that, and I would need someone to retro-fit a small heli gyro between the receiver and steering servo.

Mugler, I do have a question about the Repugol ...can it roll up and then lie perfectly flat? (the website seemed to indicate that it did come in rolls, but that may mean that it wont lie flat unless glued or nailed. If not, it's not really worth testing, as the main drawing point of a well-designed dNaNo track is convenience. If so, then I'll test some of that too: in theory (which rarely leads to what works) it seems like a smooth, grippy and thin surface, with one small advantage over foam in that it (may) have flatter seams.

Stay tuned for more of my findings as I progress in the testing. - Lorne

Prior to the release of RCP I had good luck with PVC pond liner.
