Finished mine up last night and took it to a local indoor carpet track. I'm overal impressed with this truck. It went together very easily, and drives great on the track.

I thought it was the clicker at first, but soon realized it was a stretched belt. I tightened to tensioner up a hole or two and it was fixed. Here's a pic of my setup....
