This airplane was an improved F-5 fighter that had a new and more powerfull engine, better electronics, but the overall details of its father. It was facing the F16 as the cheap fighter. And it lost. Only 2 were made, and used as testing. As a kit, its simple but with adequate details. Not many know what is this model about, as it is a rare airplane, even if the kit is common. nice to be near a YF-16 prototype.
