Just Google ''Giant Scale Twins'' . They are plenty strong, I also used 2 alignment dowels at the front and rear of the wing. I have some pictures in my 1/5 scale BT-13 build thread here in RCU.

I guess I just half to try it because somehow I cant picture it being very strong. Have you ever seen the Sig wing joiner. It is similar to the one on giant scale twins only it does not have the screw go in on an angle and there is no notch on the aluminum bar that slides into the female section. Seems like if you gave the wing a good tug, it loosen or even pull right out.
