Ok, I'm stupid. I thought that in 7.PNG, there were a couple aircraft on the top. Those are the engines inside. I ASSumed they were aeroplanes. I'm stupid.
Still, it might be a worthy project for scratch building. And it might've been a lot more successful than the Zhuchenko Aerostatoplan, a tilt rotor VTOL design built in Yugoslavia in 1937 by Nicolai Zhuchenko. Looked kinda like the V-22 Osprey, but instead of a pair of cross-coupled huge engines, this one was powered by a 50 horses, and the pilot was more a "pilot", because he had no controls, just a seat. And made a lot of noise, enough vibrations to scare the hell out of the pilot, but not even a hover of a few cm. I have the 1/48 Kora kit, and after a lot of examinations of the few photos available, with a few mods, it'll look a lot better(I'd still like a few shots of the interior, though, especially the cockpit and engine location. the little resin engine supplied with the kit doesn't even barely resemble a real Walter Mikron, and the fuselage of the model has no location for it, even though the instructions hint at one). And I have one huge beef on this. PE brass is nice, but not as landing gear struts on a model, especially a resin one. But the spares box is always quite generous. Biplane wing struts can make for some nice landing gear struts.
