Learned my lesson today. I have been out of racing for over 20 years. I have had my TC6.1 built for a month now but my schedule has not allowed me to get out to the track yet. So I took it to a vacant parking lot today to run it a little. It only took a few minutes for it to start making a loud rasping noise, kind of like a playing card in bicycle spokes. Took it back home to find small rocks stuck in both the front and rear belt pullies and the spur gear ruined. I guess touring cars are just not meant for anything but a prepared track. I do not remember my old 1/12th or 1/10th scale pan cars being so sensitive to debris.
Hopefully I will get to the track next weekend.
