Mmmm. So in summary:
You've designed and priced up a car basd on the BJ4 design, at $200-$400, without actualy building it.
After a few harsh words from the nay-sayers, you beieved in your design enough to cave in instantly and move on to an Acadamy based car.
Then when that was poo-poo'd you loved the re-thought out plan so much you switched to a Corrolly layout.
All this brainstorming is fine, but why say you have a product, priced and ready, then change it numerous times because of comments on a forum. Surely if you have designd the 'sweet car' you are claiming, you should carry it through no mater what people say?
Unless it's all bovine excreta.
