In the US all planes are weighed with batteries in the plane. Most planes out there will make weight, you just have to pay close attention. But the ONLY contest in the US you will get weighed at is the NATS, and that is only if you are in the hunt to win, even in the lower classes,

Actually this would be true in most cases as both glow and electrics are weighed with their batteries in. I'm sure there are glow/cdi fliers out there that would love the chance to be able to pull their batteries out at weigh in time.......
