If I were joinging the ends, that would help a lot. For edge joining, that makes the joint weaker. At least, with woodworking projects it would.You may wish to look into cutting a "key" in the edges to be joined,

Whoa there...I meant no offense. Use what you're comfortable with. I'm sorry for the "complicated" comment. It was meant in jest.
>>>>OT, No offense taken. Nor am I going to argue about weather one can or can not use CA in edge jointing, one could use chewing gum. However DJ is about to do something he hasn't done before and wants help with the best method & materials for the job. Your " complicated" comment just didn't fit the request, and your choice of materials was way flawed. I am stating as clearly as can be done in the Typed world of computers CA isn't the adhesive to be used in this case..PLEASE DON'T DO IT. Any or the aliphatic resin carpenters (Yellow) glues (Elmor's, Great Planes or whoevers) is the best choice Glue for this Joint. This is the help DJ asked for.
>>>>DJ don't forget the double glue joint method, wadding thou all these distractions no mater which glue you use (except CA) the dryed double glue joint will be stronger than the balsa wood itself. Waxed paper both sides and multi booK weighting will help keep the slab(s) flat while drying overnight.
I wouldn't say the CA is a "Bad" choice. It's may not be the best, but certainly not bad.
>>>>As I said it is not a bad choice.. it a SUPER BAD choice..please don't teach others bad modeling habbits CA has no business being used in this type application. As was explained in the eailer post.
I would never recommend something that I hadn't done myself. It may be a "bodge", but it's worked for me. Maybe I've just been lucky.....a lot.
>>>>>Yes; you certainly have been lucky and maybe a lot. This is exactly why I love this forum. We can exchange "experiences" and Learn what we've been doing that could (should) be done differently to make our models better, safer, longer lasting. Sometimes it's hard to hear, but sometimes we also have to learn from our experiments or mistakes. OBTW sometimes crossover experiences are of little help. Stresses on model rockets are far different then those on freeflight R/C or even static line model aircraft. Lets' try to give folks the BEST methods and materials for a given task.
For sure express your experiences, we all want to hear what everyone else is doing but if we find others have a better way, more "experience" or better info on a method or material saying ha! this is a better way, or try this method for stronger results.. with some explaination as to why it's better then take it for what it's worth, Good advise. The more we learn the better our modeling will be. That's what I ment by "let's give folks good info."
Hope this is taken in the good spirit of passing along knowledge.
Fine looking fillets on your Big Red Max OT, good job
The 15" wings on this Bomarc 1:13.25 Scale are 3/16" edge glued balsa just at the prob tips horizontially across the span. This slabs are 45 degree butt joints with ambroid cement. Sorry I don't have anything closer, but the seam is completely invisible on very close inspection.
