This build on rcgroups is amazing. The builder made molds of what looks like the 21st Century F-104 and made it a functioning R/C jet. He refers to it as one of those pre made models and I can't imagine what other model it could be. He decided to enlarge the wings to tame the flight characteristics but the fuselage looks stock. This is a very long thread but worth the read. Check it out.
