I fly a Calmato Sport a bunch. Assembled it in September and it's been flown every week since. I liked it so much, that I talked a flying buddy into building the high-wing Calmato.

They are both excellent flyers. And they're basically the same airplane as a high-wing and a low-wing. And the wings are joined the same way.

Kyosho's idea of the tape is to place masking tape around the root of the wing. Epoxy is squeezed out when the two havles are pushed together. The idea is that the excess epoxy will smear on the wing and make a mess. The tape is to deal with the mess. Unfortunately it doesn't deal with it very well.

What you really need to do is neaten up your glue application. It isn't hard to do.

Use slow epoxy so you'll have time to do the job right. 5 minute won't do it. 15 minute can rush you enough to screw things up. Use 30 minute. Don't use globs here and there. I've used solder brushes, Q-tips, and tongue depressers. All work. The idea is to get a thin coat of epoxy on one root rib that covers almost all of the rib. Then get a thin coat on the other wing half's root rib that covers it. My favorite tool nowadays is either a popsicle stick or tongue depresser. It can glob the glue on and then scrape it out over the area smoothly, uniformly, and quickly. Both sides can be coated in a couple of minutes without any mess, and no globs or thick spots anywhere.

You'll then bring the two halves together and pull/push them firmly. If any epoxy squeezes out, you put too much in that area. If it does, it shouldn't be much, certainly not enough to worry with immediately. Just focus on keeping the two halves aligned and..............

Tape the two together with 3 or 4 strips of masking tape top, and 3-4 bottom. Have the strips of tape ready before mixing the glue. 6 inch or so strips work great. Tear 'em off and line them up on the edge of the workbench.

When you bring the two halves together the joiner spar will do most of your alignment for you. But you need to insure that the LEs and TEs line up and stay lined up. The TE is easiest to control. Bring them into alignment and put a small piece of masking tape over the seam and that'll usually be good enough. Check the LE and put a small piece of tape if needed.

Now, the long strips are put on span wise. Take one and start it on one side. Get a couple inches stuck on one panel, then pull the free end taut. Keep it slightly stretched and pull it down over the other panel. The tension in the tape will help it go down straight. And the tension will pull the wing panels together. Do one side and check the alignment. LE and TE still aligned? Now do the other side.

If you do the bottom first, the dihedral will help you out. You'll see how when you do it. When you start to put the spanwise strips into the dip of the top of the wing, you'll really see the pulled tension in the masking tape working to make a good epoxy joint.

That's the taping job.
