<p class="MsoNormal">Hello my name is Yegor, I&rsquo;m new to this forum as well as the hobby. A friend of mine gave me an engine Fox 45, it was rusted inside and didn&rsquo;t work, I manage to fix it, he also gave me a propeller, I believe it is 11x5 . I would like to build a small plane, I have the blue prints of the plane I have in mind, but I need help figuring out where to start from and with the calculations. For example: what material should I use, how big can I make the plane with the engine I have and how much lift power will it have. Any other advice would be greatly apreciated.</p><p class="MsoNormal">The engine manual:<span style="mso-spacerun:yes"> </span>link</p><p class="MsoNormal">Blue Prints (sorry text is in Russian) : link</p><p class="MsoNormal">Additional Pictures: link</p><p class="MsoNormal">Information about the Plane: link</p><p class="MsoNormal">I know it is a hard model, but I would like to try and make it.</p><p class="MsoNormal">Thanks in advance</p>

Yegor,

That certainly would make a very interesting model. It's a design that is almost forgotten.

But to build a flying model of it with no modeling experience is just not practical. Build and learn to fly a half dozen models first will prepare you for the project.

Structurally, about the closest models that I can think of might be some of the old Don McGovern designs that he used to publish in Flying Models magazine back in the 1960's and 1970's. He designed a number of seaplanes and published them.

The Sea Horse has a similar wing/engine configuration, while the Piranha and Mako Monster a similar fuselage design. Perhaps looking closely at these plans would help you develop your design.

You probably don't want to hear it, but the correct thing to do is to build or buy a trainer first. There are two sides to this hobby- building airplanes and piloting skills. A great pilot can overcome bad building to a point, but a good builder can never compensate for bad piloting. You have a really interesting project in mind that should get the respect it deserves. To do that means that you learn to be a good pilot first before taking on a plane as difficult to fly as that one. If you want to fly off of water, a trainer can be equipped with floats. But if you build that seaplane you linked to you will probably wreck it on your first takeoff attempt and never get to see it fly. Even if you do manage to get it in the air before it is too damaged to fly, you won't have the skills to land it without damaging it. So learn to fly with a trainer plane, then move on to the models you are really interested in.
