They really aren't that fragile. Of course the front arms are the most, but they really aren't that bad. I've replaced more on my tc than the f1 in the same time period. F1 could catch on, it is at my track. It just takes a few dedicated F1ers to get out on the track. The chassis don't cost much, you can get a 3racing for $100. Make it a class in big events (see IIC) maybe the upcoming 2012 carpet nats (hint hint) and it will get noticed. Get more car manf. To produce F1 specific chassis (hi speedmerchant). Has to start somewhere. There is more people interested in F1 than you think. But a lot of them just don't want to be the first to get one. I have 2 f109s one wide and one narrow with f104 frontend. Cars are beautiful, just a neat class
