Doug, It looks like a very nice chassis and I hope you can get something going with it. A word of caution though. I have several chassis on the road at this time. Some years ago I thought the same as you, sell enough to help keep my own hobby going. I have sat down and tried to analyze what kind of "profit" I have made from them and I can safely say that I never really made money on any of them. The reasons are simple, by the time you warranty your work and pay for your manufacturers liability insurance and then lay awake at night worrying that one of your customers will do something really stupid and hurt themselves or hurt somebody else, you soon find out that there is not enough money to be made to cover you. As to the warratny issue, no matter who you sell your stuff to there will always be the ones who will bug you to death because they don't feel soemthing is quite right. and then the liability issue, I had an insurance agent who was writing my liability rider tell me that the company would no longer cover me with out a safety certificate from a licensed engeneering firm. that's when I quit building chassis altogether. In this litigation happy we have today be very carefull. Just my two cents worth.
