Google FAI, F3A, CIAM, RULES and read up.

There is a long history and a rationale behind every rule - ranging from safety, to transportability of models, noise, etc etc etc, that have been debated extensively in the world pattern community.

Going through that history and the debates is a pointless exercise. Surely there was strenuous objection to every one of them when they were being discussed, and their impact on participation was considered. However, at the end of the discussions a consensus was reached and here we are.

And where we are is pretty good. What other competitive activity has only THREE rules regarding the equipment used, for crying out loud?

There is a FAI rules proposal process through the NSRCA/AMA. If you don't like the rules, that is the proper channel to work through.
