Skyhawk Glider wing mod and reinforcement

I have a skyhawk glider. THe wing is made of butter and I need to either change it or reinforce it but I have no idea how. Does anyone think that this plane could fly with the Aerobird Express wing attached to it?

This is the Chinese SDM glider sold by Wonderhobby, ete:

There's like, 18 different "SkyHawk" gliders out there as well as motorized planes.
Could you be a little more specific?

Usually a carbonfiber rod down the middle does fine. Butch

Doesn't that wing already have a rod in each side, connected in the middle??

That's a decent looking plane. It probably lends itself easily to performance modifications like a brushless motor and lipos. I sure wouldnt mod it by coating the wing with 5 minute epoxy or any other epoxy - that will gaurantee a brick.

Seriously, what is it about the wing that seems too fragile? Most planes dont serve very well at pounding nails. Has it flown yet?

No, it hasn't gone up. I do not plan anything particularly agressive for this plane. I have an aerobird 3 and that can take a lot more. But there are plenty of threads of people indicating that the structural integrity of the wing seems compromised everytime the plane makes a steep turn. It seems to fold, which is strange.
Today I was looking at it and realized that it is entirely possible. Thewing is not rigid at all. It does have a rod going through it but it is evidently not enough.

The fuselage is great so I do not want to looke it in my first flight because the wing caves.

I have several of the earlier version of that plane. The 2 wing rods connected in the middle with a plastic connector and the wings were basicly screwed together with 2 plastic connectors.
I would actually remove the plastic connector and epoxy a 2" aluminum tube instead. Then lay a piece of carbonfiber rod, about 1ft long along side the rods on the plane and epoxy them and then run some tape over it. Butch

OK, I got it. The skyhawk has a very narrow channel where the connector, which is also the reinforcement sits, and yes it is made of plastic. I would like to place a carbon fiber rod but I am not sure how to make the channel go all the way to the end of the wing.
I am still thinking of getting an aerobird Extreme wing and trying that on.

To make the channel for the fiber rod, lay a steel straight edge on the wing with one edge where you want the rod to go.
Use a soldering iron to melt a shallow groove for the rod along that edge.
Use some 30 minute epoxy and coat the channel then lay the rod in the groove. (The 30 minute epoxy will give you the time you need to do the work.)
Then cover this with clear packing tape and while the epoxy cures run your finger back and forth across the tape and over the rod to keep it smooth as the epoxy cures.
