A single 15mm joiner works well enough at 13 AUW. My Bergfalke 4's wings do flex when viewed from the air, but look normal enough from the ground.
15lbs might be pushing though...(Motley put two joiners in his version)
I put two in mine too.

I concur with the others. I too have used double joiners when at that weight and above. However it has to be said that I tend to throw the model around a lot. For gentle flying a single should be adequate.
That leads me to think that if your wings are flapping around a lot then there is something else going on with your joiner system. Time for some investigative surgery perhaps?

Big thanks to everyone who took the time to reply, I took the top off the model tonight to get a look at the wing joiner setup and was shocked what I found
I'm going to have to revamp the whole wing joiner setup plus I'll put in the second steel rod
Only thing I need to know is what the proper dihedral is
Thank you all

Usually around 3 degrees per wing...
