Yes, Mr. Jools, you are right. These wings are definitely not strong enough.
So, I am going to glue 3mm thick balsa strip on top of each wing. That should make it strong enough.
Thanks,
Aaindthu

So I did the test with two batteries, esc and motor in place. Because the glider is not finished yet and it is likely to end up heavier when finished I used two batteries for this test(one 3s/2200mah, and 3s/1000 mah,) even though I will be using only one for flying.

The wings flex, but not too much. Looks okay to me.

I have glued 3 mm thick balsa strips along each wing, but only on top of the wing.
I will do the same on the bottom wing as well. I don't feel any significant increase of weight due to the balsa strips.

tried to make a clear plastic canopy out of coke bottle, but didn't work.
So, I'm making a foam canopy. I'll put some paper mache over the canopy and around the edges and cover it with black tape, that should look good.

I've also elongated the nose to get the CG right.
Almost complete.

Your wing load test looks quite adequate to me and should allow gentle aerobatics.
There is nothing wrong with "adjusting" the length of the fuselage, within reason, to get a suitable CofG position.
