There was a stand way off scale F16 (kind of box shaped fuselage and flat bottom wing) set of plans that I used to build the jet with an RK049 fan and TD .051. It barely flew like most little fan jets of the era. This was 1980 or so. I wish that I still had the plans. It could have made a good EDF project today. As I think about it, the plans may have been from a project in one of the magazines. Does anyone out there remember this plane?
