    Default Use of Hysol epoxy

    is Hysol EA9430 the epoxy recommend by Kitfox for gluing in the ribs?

    9460 is what you are looking for.

    Somewhat related - Does anyone have a guess how much hysol is required to complete an airframe with the quick build wings?

    2 quarts ( One A One B) Would be close if you went fast but it does expire.

    I agree, 1qt. of each should be enough.

    I am on my second set of Part A and Part B and think I will use most of it by the end. Must admit to wasting a fair bit at first until I got a better handle on how much to mix up at any one time!

    Yes, mixing up the right amount without wasting is the key.
    I used 2 qts. of each, but I did not have quick build wings, and the wings use a lot.

    2 quarts will be enough for me. I found that it is easier to waste some and the 2 quarts appears to be more than adequate. I also bought the quick-build on the wings.

    Look at the factory made ribs to see how much "ooze" is required. I.e. Very little. Most builders use way too much adhesive judging by some of the pictures of home built wings.

    I did wings, tail, stab and several other bonds. I was generous but not overly so. I have a little more than a pint left over.

    I would agree the key to less waste is to mix less than you think you need. It will save a lot over the course of the build. It takes only a minute to mix up a dab if you need more.

    Just a reminder as we are still in winter. Hysol has a tendency to get lumpy or crystallize when it gets cold or old. Just put the amount you need in separate paper cups and warm the two parts with a heat gun. It will soften and melt back to a smooth fluid. Then mix up the amount you need.
