RE: Scale Combat Wingspan rules?
I did look at the JK Aerotech planes, they look like good kits/planes, but most do not conform to the AMA's 40" minimum wingspan.
Even the Great Planes Combat ARF series come up short in the wingspan area.
I'm a OK builder, and could easily build from plans, but just getting started I don't want to spend the time to scale up plans until I get a little more into it, and then it might be too much time involved for a combat plane that is at risk of destruction with every round.
My opinion would be to drop the minimum wingspan requirement so that new guys can easily buy, build or find a "legal" plane to start with. They can always go bigger if they are so inclined, but why AMA would exclude what kit manufacturers are left and make it hard for the new guy is a question.
