Ditto, the best thing one could recommend is to print off the Flying and Judging Guide, read through it and attend a seminar.
Also, download the judging summary card. It has 99% of what you need to know on a single page. Saves LOTS of wading around the nearly 40 pages of the rulebook!!
Also, almost all CDs will allow the CA 2x2 to fly any class. At least that is the latest word from what I hear around.
