A simple 3d model of the outilne of the LPL soviet theoretical concept for a flying submarine

the model is about full scale but designed to be scalable both for 3d printing as a simple miniature or as a starting basis/mold to design an rc model around

the center of lift of the design seems quite far forward, though I've tried pushing it as far back towards what you would find in a more normal plane design as possible without deviating visibly from the original design concept
