    Its been 20 years since the last Boorabee was built, I still have all of the moulds excepting the leading edge mould which I gave to a friend to use for his Karatoo.
    I have learnt 3D Cad, mainly for 3D printing and CNC, I like to keep my mind as active as possible, am building a new CNC at the moment IMG_20191119_094433.jpg

    Even though the Boorabee was a great project, with all but one still being flown after all these years, I don't have the energy or inclination to see it reserrected.

    Chuck told me that he built a large 3 wheel tube bender that used truck tires as the rollers.

    According to Chuck Slusarczyk bending the tube made it stronger. He cold bent the CGS Hawk tubes on a large 3 wheel bender.

    Hmm, the Boorabee, could be an interesting bird if all the fairings where left away!

    ...and the engine was in the front ;)

    For some reason pushers never grabbed my fancy, even though airplanes like the Beta Bird and Whing Ding are high on my favorites list.

    This Thread , gave me a Good concept for the pilot's visibility
    in different sitting positions ; relative to the wing !!

    I "Had" envisioned, turning my Exxtacy glider, into a stand-off
    scale BKB-1 ; the wing platforms on both gliders kinda look
    close , (from a galloping pony) .

    Then
    i separated the wings and placed them on boxes ; and sat
    in the middle with my head about arm-pit height, above
    the center-line of cord.
    Dang
    did NOT like the visibility , one little bit ; i mostly saw
    the top of the wing. Sitting up above the wing , like
    some of the shots on page (1) ; it was a LOT better !!

    Now i'm wondering just how small a fuce i could fit
    my 205-Lb body in ; while laid-out suprone, like i'm
    flying my Paraglider ?

    It's back to the drawing board , for now ; i just know
    for sure , that i won't be laying prone , like i've done
    for the last 43 years, below a Hang glider wing.

    Bille

    51DE0926-9F97-42BC-890C-70AE70AB6891.jpeg Tractors are better to fly than pusher aircraft, pushers are always much noisier. I’m not sure that a tractor is the best configuration for such an exposed pilot, the slipstream will prove very uncomfortable.
    If you were designing a very light (part 103) tractor, the obvious and least complex arrangement would be a single high ,say 4” tube, with the engine, wing and tail attached and the pilot and UC suspended below - like the above.

    Are there any news from the Ranger front, has the additional plywood arrived?
