Ok on the ID cards in the SIG kits. There may be other kit makers that furnish it but I'm just familiar with SIG. Before you use it, go make a few copies of it so you don't have to buy any more. I would epoxy it on the inside the fuse by the receiver or servos. If you want to fuel proof it you can thin some epoxy cover the ID card or get some clear dope. I think a lot of people don't realize that the ID in the plane is part of the safety code and may be just cause to deny an insurance claim.
