....as a side note. all my kids have put QRcodes on their planes. anyone with a scanner (which is most people now w/ smart phone) can scan and see their name, phone number, ama number, and anything else they want to add. plus it looks kinda cool. yes, you can write your name, but this is just diff.
you can google "qr code generator" and there are multiple free ones. some will even create and image for you.
sorry but, you should always have your name and number on your plane in some form. if your putting it in the air, you need to take responsibility for it.
