Also, i calculated the cost for a complete aircraft and i believe that it is affordable enough.

It's a long time since my last post.
The month was too busy. I had a lot of technicals problem with the dam's rebuild. Finally, I solve all of them but it wasn't easy. Now its' vertical slide gate...
Dear Mr Matt,
Very good question. I ran a lot of real-world models in my PC and results was getting close to experimental.
Hello, as i promised i make some screenshots of Lisa software. It will make more clear how i make finite element analysis.
If you go with Lisa, you can choose laminate material from the library....
Yes my friend. I make a mistake, I am sorry about it.
Thank you very much for the comment and for your interest! :-)
Good evening my friends!
The second part of the design:
Now you know what do you want and you are ready to start the computational part of the design.
1) Select a good airfoil for your...

Dear friend,
Hello from Greece! I had spent a lot of time on research previous years. I design an all composite 2 seat airplane.
I am a civil engineer and i will be glad to help you if you need a...
I would like to make clear that when I tell "ultralight" I refer to European ultralight. I told that "fly an ultralight in Europe".
About everything else, I am an engineer. I design it and I will...
Happy new year! Best wishes for 2019!
I start a more detailed technical report. Not only because I want to advertise my design but additionally because (I think) some people want to design and built...
Stress forces resulting from a dynamic responseanalysis (for loads in flutter condition) in the LISA finite element program.

I used naca 66-009 only for vertical and horizontial stabilizer. I didn't publish main's wing airfoil. I don't answer in other question because i think it is on naca 66-009
Dear Bob,
It is a technical report of aircraft's analysis and i didn't include structural details.
I am proud and lucky to discus with you because you have a lot of experiense. This aircraft...
Dear mr Bob,
I choose it because of better behavior and comfort on rough concrete surface. In near future i will change. But for the test flight i believe that it is safer a bigger tyre. I will...
I also made some animations
1)Pressures around the aircraft at speeds just before stall with fully extended flaps

My name is Christos and i am a civil engineer and aviation enthusiast from greece. First of all i would like to thank you all for your interesting and useful threads. It helped me throughtout the...
