made one and it flies straight and true - although I dont have a room big enough, more interesting enough, was the guy who makes paper airplanes - like the Beoing 777 - 300 out of manilla paper, that beige stuff from office world or WH Smiths for folders, the detail and complexity of his model is astounding, he has the undercarriage as a test rig and not only does it retract (manually i must point out) it swivels and the piping detail is amazing, when he finishes the wings they will have panels like the flaps and airbrakes moving, he even has an engine where the reverse thrust operates, to show the inside, he has the cabin top fold out in sections which has the over head lockers open etc, though he does say that he is asked if the seats recline, which he unfortunately says they dont.
