I actually used to be involved in RC airplanes and have seen this kind of thing before. It's cool but I don't think he should have picked an F-14. Because he didn't engineer swing-wing (I don't blame him for it, what a bitch on a model) it kind of looks ugly flying around with the wings extended. If he wanted a twin he should have gone with a F-15 or F-18. The problem with model jets is all you get to do with them is do speed passes with them and then pick one of a dozen turnaround manuvers, then do another speed pass the other way.
A funny thing though, when model turbines come out one of the big name model jet kit manufactures (Bob Violett I think) just modified an existing jet design for a ducted fan (piston engine, internal, with fan blades instead of a prop) and went so fast on the test flight to fly it apart! After turbines became more popular the AMA (the USA R/C governing body) made a speed limit of about 300 mph (480 kph).
Last time I checked turbines were $10,000-$15,000 each. It may have dropped some though.
