    The Sprat 103

    That is not the information I found in an accident report. That is what the designer said happened. The official report said small variations were found but none assigned as reason for accident. That i could have been pilot error.

    Controlwing ULX-17 from Argentina

    but this is a global, the supposed designer is in france and says he has patents in the European Authority. This search included that and no patents exist. Second the inventor has to be listed no matter where you get the patent and he is not nor is their an LLC with the suposed inventor or...

    The Sprat 103

    Over 10 years later, not a single Spratt 103 is flying. Bernard Geffray claims he has 5 patents well....... Well nothing exists world wide, he claims the plane has never had an accident but the only one built besides his, the pilot crashed and died. So much for his design and all his threats...

    A new idea for a UL Biplane for the UltraVair

    Well, while I do like both designs alot, they are quite different from what I am doing. As I post more of the design you will see that it takes no reference or similarities from either. The Main Goal of this design is for it to be affordable for the average person and not a complicated build. I...

    A new idea for a UL Biplane for the UltraVair

    That is the one of the upper wing panels, ailerons are only on the lower wing. It is not aerobatic so two sets of ailerons are not needed. The airfoil is an LM7610, been used on a few planes. Leading Edge used to sell them. Pretty efficient for low speed when not heavily loaded, on the...

    A new idea for a UL Biplane for the UltraVair

    OK, so now with some time I am sitting down with SolidWorks to design a new Biplane for the UltraVair. Long wings for better span loading, so less HP. Here are a few pics of the wing design. Just getting started, tube spars and ribs along with the trailing edge done. Weight is 13.43 lbs for the...

    reo12, what is your name? I talked with William many years ago and he put me on to Fletcher. You seem to be hiding behind a screen name. Please post facts with your evidence. I have the COMPLETE yahoo group database. So tell me who you are and I will look up your accusations to see if the proof...

    What happened to the Ultravair?

    I also wanted to post the email that turns everything over to me from Fletcher Burns. Just to make sure that there are not people out there selling the ultravair manual illegally or giving it away. When they don't really have the rights to do so. David

    What happened to the Ultravair?

    I am looking thru the records and I do not see a Matthew Long, could have been before I took it over. I would have to actually see the copy you recieved to see if there were any changes after that. There will be an updated manual with instructions for more cc using VW cylinders and results of...
