    After nearly a foot of snow last night, some idiots still drive like it’s summer. A kid in a Honda speed up to pass me just to get one car length ahead ignoring the icy roads.

    Where do you live Boyle ?

    We have +3 C and almost no snow ( which is unusual ).

    Australia is warm ( +41 C in Winton ): http://www.foreca.fi/Australia/Winton

    I am a bit angry the climate change is not turning Finland into subtropical region.

    Built for 1.28g’s was an crash looking for a place to happen.

    Design failure or lack of it ( as here ) is pretty obscure…as there are even free programs to define the spar web and cap thickness for each material.

    Anyway if you buy all the material from Home Depo the disaster is about to take place.

    This guy cannot be serious.

    Thanks for sharing! The word accident is the legal term as far as air law is concerned however one should say “crash” when the event is caused by negligence etc. Years ago I was a policeman and we never used the term accident for motor vehicle collisions.

    Here is a crash investigation of a small homebuilt; https://www.youtube.com/watch?v=2EaZdeTERjY

    But we were actually discussing airplanes here, stealth fighters and unlimited racers. How about we get back to that subject, would be much more interesting. Or maybe topspeed could design an ultrasonic business jet with a cruise speed of M 6.2 at 81000 feet and a range of 10000 nm, with VTOL capabilities, and 50% of thrust provided by solar energy? Maybe he can design one by next Saturday?

    Are you drunk again ?

    I have been working on Hippiäinen for 2 years and 4 months…check my blog.

    Decision to make a wooden indigenous aeroplane started in 2007 as I became unemployed and Nokia people were let out ( who consisted 50% of my clients ).

    [ATTACH=CONFIG]242130[/ATTACH]

    I am finally testing its aerodynamics ( of the foil in 1/3 scale ). Like all real aeroplane designers do. Cl_max is without flaps or slats. I also have several aeroplane builders and pilots working for it here..not on daily bases, but when needed.

    2009 it was still a pusher with retracts.

    [ATTACH=CONFIG]242131[/ATTACH]

    Fine, that was a flight of imagination, so it all adds up. Just let us know when you have become an airplane designer, having actually designed something. All the systems etc.

    I already have…for the Hippiäinen…minimum AC. Some I will leave as it goes to be solved. I am working on a highly efficient VAWT at the moment…which uses my own designed air foil…and all other systems excluding the generator. It is a working wind turbine. I will fund my aeroplane division projects with the income from that system designed for Africa.

    Enjoy like I did 40 years ago; https://www.youtube.com/watch?v=ufyPtHpVnug

    That you had an R/C model once again proves everything. You asked earlier whether I think you should be posting on modelers forum instead. Yes, I think you should. Except that you probably already are banned at least from the Finnish one…

    Going back to Tsunami and the racer “designed” by you, I am fully aware of speed limitations of propeller driven airplanes. The big main difference between Tsunami and your “design” is that someone actually designed Tsunami – and built it. And no, I do not believe that anybody from Norway, or elsewhere, would “offer you a couple of Mossie engines”… Dream on.

    Don’t you just enjoy repeating from how many sites I have been banned.

    Go see the movie ” The Flight of the Phoenix “. I made my decision of becoming an aeroplane designer based on that movie.

    Sounds like a Japanese Kei car, a little lightweight box on wheels with a low power engine for pottering around town. But even then, it’d be hard to squeeze six people into 800 kg while meeting crash protection standards. Kei cars are no longer 500-600 kg, but more like 700-900 nowadays, & have a four passenger limit.

    Very interesting detail about japanese cars swerve.

    The prototype Me 262’s were also tail draggers. They were difficult to get in the air because of the tail section being masked by the mainplanes…

    That is correct…history is a good source for information.

    This AC does not have that problem.

    Here is your quote:

    So lets review my math from school, shall we? Lotus Exige 913kg – 800 kg (your imaginary car when equipped with enough batteries for 100km range) = -113kg.

    You are claiming to have designed a car that seats 6, has gull wing doors and a hatchback, and weighs 113kg less than a Lotus two seater sports car.

    There is a 2-seater VW that is just 300 kg empty.
