This is a long term project I have been working on. The nose section was, somewhat difficult, to achieve. The limitations of paper and making something that looked like the actual craft is still a work in progress, but I am getting close. There is an error where the rudder meets the hull, it's easy to fix, I am going to deal with it when i get back there again. The Renders are just visual aids (as everyone knows I', sure). Every part on this model unfolds. This is one reason it has taken so long. I have made the nose section to make sure it would work, and it does. So, that's what I'm working on. The Half model does not reflect recent improvements. A long time ago there was a guy on this forum who nitpicked the heck out of me about this craft. At the time, some of the literature out did not have all the specs. I called the Moscow Hydrodynamic Bureau (similar type name, can't remember it exactly), which at the time, was in charge of this project. They verified what I had read, that it has a maximum ceiling of 10,000 ft, at a great loss of fuel efficiency.
