To find more information about the rockets Bdale and his son have built, see [Garbee Rockets](http://www.gag.com/rockets). +
+As Bdale and Robert became more experienced in the hobby and started to build +and fly more sophisticated projects, we started to feel limited by the +existing electronics products available.
