The AMA is not going to, nor should it be involved in the decisions you noted above. Not practice or feasible, or advised for that matter. The club decides, pure and simple. There are some clubs that are electric only, should they not be afforded the full protection and involvement from the AMA because they don't allow nitro or gas? Many don't allow turbines, for the same reasons some clubs are only electric (noise, size of field). If you're wondering what a club is all about, look them up online, most have their bylaws posted. Visit some and talk with people about what is and what is not allowed. Not that you have or would, but just in case if you don't agree with the clubs position, best to not get vocal about it before trying to join. Might not make for the best welcome aboard. You'll find different clubs have different traditions and expected ways of behavior. Best to figure that out before you join.

Good luck.
