    I am trying to decide if I will use fabric or metal to enclose the gear legs on the AcroSport. I used fabric on the SkyBolts and always had a drumming problem. This time I have added an intermediate rib between the fuselage and axel to attach ?? something to. Reguardless of what I use I am considering filling the void with foam to cut down on the drumming.
    So, my questions are - -

    1) If I use fabric will the covering chemicals disolve the foam ?
    2) Will I have a problem with moisture not being able to get out ?
    3) And last, would it help stop the drumming if I shaped the foam so it is thicker at the center ?

    Thank you,

    P.S Smizo, you need to work a little faster getting the streamlining of your gear legs photo's posted - - I am waiting :)

    1. Maybe. 2. Could. 3. Probably.

    My concern about using fabric is you will not be able to inspect underneath the covering or foam. You have probably seen Dana's pictures. I saw his plane when a friend owned it almost weekly and never saw the problem. If you use Stewarts coverings, it should not melt foam. I know of someone flying a homebuilt with foam ribs covered with the stuff. Water, may or may not be a problem. Depends on how well sealed the covering and foam is. A foam insert should make the fabric work well; done right it should not drum. The choice comes to, should it be light fiberglass instead of ceconite? The beauty is its a homebuilt; you get to build to what suits you.
