I did that to my first balsa build which was a pure glider. It happened while I was high starting it. held up great with no signs of stress for the first few flying days, but one day it just clapped its wings! When I finally fixed it I decided to put my power pack F motor in it so I won't have to high start it, and I now get 35 minutes flying on an 800mah 3s!
How would I find tubes that are just the right size to slide inside each-other?I’d look at a carbon fiber tube that when about half way into each wing half.

My spar arrangement on my current build looks like this:You do not state what spar arrangement if any is already fitted to each wing. Also you do not mention what Dihedral angle, (if any), is used in the design.
When planning to have removal wings it is also wise to know what weight the plane is and as to whether the wings are to mount directly to the fuselage sides or if there is a central stub if wing section which is integral to the fuselage.
You will not only need to be able to support the plane when flying but also to ensure that the wings are properly secured in location as well as in incidence angle.
Sure, you can add massively strong structures to mount the wings but remember that extra weight reduces performance and increases the damage in the event of a crash!
I have many planes with short connecting spars most of which either "key" into the fuselage or have locating pins, (lengths of CF), to ensure that their incidence never varies.
A little more info would help in narrowing down your best solution and the one which gives best strength for weight!
Have fun!
Sorry, let me rephrase. I haven't ran into any problems yet. Do you think I might run into any later? BTW, my popsicle stick collection is pretty good quality, with very straight and strong wood.The problem might be the popsicle sticks. Face it, popsicle sticks are made from cheap wood. I just went through several dozen popsicle sticks trying to find a few that were straight and stiff. Every stick I looked at was rejected for some defect. I ended up cutting my own stock on a saw to get wood that was straight with clean grain. Another cheap source of clean straight wood is paint stirrer sticks.
