Hello,

I've been in the hobby a while, but have never mastered the art of gluing 2 wing halves together without making a mess of the covering around the glue joint.


Regardless of how many times, you trial fit the parts, when you apply the glue it sudenly becomes a high pressure environment to get everything lined up without having to worry about making a mess

Any advise would be appreciated.

I use 30 minute epoxy. Gives lots of time to work with and cleans up and thins with rubbing alcohol.

+1 for Jetmech05.
you can also run masking tape around the wing on both sides of the joint so any excess epoxy runs into the tape and not the covering.

(of course, the simplest answer is to glue the wing halves together before covering the wing ) obviously that won't work on a pre covered (arf) wing.

Make sure you use LOW TACK tape, otherwise you risk lifting the covering. Ask me how I know this.

I drill several small holes in the ribs that are to be glued together. The glue then squeezes into the holes instead of out between the wings, and it also allows for a tighter fit.

All of the above suggestions are excellent. In the end if you are unhappy with the appearance of the joint, cover it with the appropriate color of 3M plastic tape.

All of the above b ut I also smear a bit of raw castor oil on the covering and the epoxy wipes off really clean with just alcohol before the epoxy sets up.

I use Epo Grip Epoxy . It is much slower curing .(about 4 - 6 hrs. ) plus it stays where you put it . It doesn't run like regular epoxy . It is more like putty . If you use a rubber glove and wet your finger you can smooth the joint just like glass . The nice thing is you are never rushed , you have lots of time to get everything set the way you want it . Its very easy to work with . I hardly ever use regular epoxy anymore ..

Ken, didn't RC Ken or Mike do an article on that EPO Grip?? I recall {I think} someone talking about it being a review. Been a couple years but they liked the stuff. I still haven't tried it.

I am not sure , I have not seen it but if they have done one I would like to see it . One can always pick up new ideas and tips .

I would use either tape (masking or clear tape, depending on what's going on), or I might use a good synthetic grease. I use a lot of teflon grease during my last build, it works like a charm. You can coat wing tubes and aligning pins in grease before you glue things together and they seem to always come out just fine.
