    How do I fix my D windows?

    Hi,

    I am a proud new owner of my first supercub. The original builder, followed the cross tube for the back window and now I don’t have D windows.

    Any idea what the least evasive fix for this would be, as fabric is completed now?

    Is there, maybe a quick kit out there somewhere, kind of like Carbon Concepts upper baggage door/ frame?

    Or has anyone added big back windows after the fabric was completed?

    The project I bought is a North Land Drawing PA-18 Wide body.

    Thanks

    Kip

    The D window frame is formed U channel welded to the frame tubes, you can get them from Univair.

    You're not going to find a solution short of cutting fabric and welding some in. There is no such thing as a bolt-in window that requires no fabric work.

    The current window is actually larger than a D window and longer on the bottom. If you're installing a proper d window you will need to somehow scab in some fabric there to close the gap that will be created. Like I said, no easy solution here.

    Well, thanks for the truth.

    I guess it is ugly window, till I can bring myself to carving this amazing build.

    I found what I consider to be a holy grail find for me……This machine is 80% complete and the only flaw is those 2 windows.

    thanks for your knowledge.

    I’d keep the windows as they are. If anyone complains about them, tell them you’ll find someone else to go flying and they can remain on the ground.

    Some builders don’t install the D window at all because you really don’t look out them much at all. Those without D windows sometimes paint a window on just for esthetics. Way too much hassle to change what you have there. Paint the “missing” section so that it looks like a D window. If you don’t like it……….start cutting fabric.

    Look on the bright side, you just saved yourself a few weeks of build time!! Once you get it flying most will not even notice the window. I think it is fine and a nice way to do it.

    I bet when the cub is done and flying they will grow on you. Definitely not worth changing

    It is nice to here, that some people actually don’t mind the way those windows look.
    It is still a Supercub at heart, even with those windows!

    Here are a few pictures of my project, when I picked it up 2 weeks ago.

    Thanks for your positive input.
    Greatly appreciated!

    I don't necessarily care for the look of the windows, but to me, it wouldn't be worth all the work involved to change them. I actually think it would look pretty good if you put a black stripe from the window, tapering down to the tail. Pretty much like the factory paint scheme of the 70's model super cubs. It would make the odd shape of the window not near as noticable, and it could be done with vinyl.

    Something along these lines…..is what I am thinking of doing when I am completely finished the build, and I have learnt how to fly it.

    The prototype FX-3 had a rectangular rear window with some painted over to leave a D shape if my memory serves. People don't seem to mind the looks.

    They all do. SS/EX/FX all paint the D on the plexi. My tastes are different, I prefer the sq rear windows.
