I have ordered from Nitro Planes also (might have the same plane, but not sure if mine is 63". Its supposed to be a .40 size, but I run an OS .61fx in it due to weight). I was never asked to prove my identity. I ordered online, entered my CC info, and presto bango, it arrived about a week later. I too would be VERY concerned about having to provide this information. I would certainly keep a very close eye on my CC acct. Did you have to send a photo copy via ground mail, or a scanned version to an e-mail address?
