Ken: I am sorry to hear that someone has pirated your model. I could understand, and maybe even sympathize with someone copying and making available a model that is out of print and never likely to be available again, but when it is so new, and the designer still available to keep it going, there really is no excuse for distributing it without permission/paying for the copies. I hope that this doesn't keep you from doing new designs in the future, I'd really like to see some of the more unusual aircraft and vehicles designed by someone who can do them justice. I'd have bought a copy but right now I'm finishing out a contract and unsure of the next job. Once that is settled, I'll be in line for the X-15. By the way, have you thought about making a kit modification to match the original shorter version of the X-15? Tom Williams, Jr.
