    Default Flaperon support Inboard end - Mk3 Kitfox

    Hi from the UK,
    I have a question.
    The two pieces of nylon? each side which support the inboard end of the flaperon pivot (one half in the turtle deck and one on the main fuselage).
    I have to replace them for my next inspection as they are cracked.
    Are they bought items or are they made to a drawing/pattern?
    I've looked in the parts catalogue but can't find them.
    If they are made parts, is there a drawing anyone can send to me (please )

    Just call Kitfox, they have them. I just bought some myself. They come in two halves that you need to cut down to the proper total width.

    The material is 1/4" UHMW.

    Mine are way thinner than 1/4" probably 1/8"
    They may have been incorrect from the start, or they may have been thickened up by Kitfox over the years I guess.

    Mine are riveted in place, at 1/4" would bolting be better?

    Forget what I said. I misunderstood the bearings you were talking about. The model 7 I built does not use those pieces.

    I redid mine a few years ago. I used 1/8" Derlin (Acetal Copolymer) sheet ordered from Amazon. When I redid mine I hinged the lower portion to match the Model IV design to make wing folding easier. They've worked out just fine.

    I have plenty of leftover material, but shipping to the UK might not be worth it.

    I hope this helps. It is from the KF3 build manual. Please excuse the construction notes added.

    Thank you everyone for all your replies.
    I'll print the build manual off and get some delrin in the UK it's easy to get.
