I would just go to your local hobby shop, buy the 30 min. epoxy and go with it, you can mix it with anything around the house .... i used an old part of landing gear for my old electric park flyer ...... the 30 min. is def. stonger and is for high stress areas or anything you want to permantently hold together. If you are going to be carting this thing around, i wouldnt epoxy it, but it you dont mind carting around a full assembled wing, then it is def. a good idea.
