I try to communicate through the electronic translator. Therefore at me it very badly turns out. That it was clear I give a photo. Green colors an axial line of model. Red color you will see that confuses me on a wing. Installation wing on Russian technical language refers to - a corner of attack.
Thank you the picture helps.
I wish I spoke Russian.

The wings are glued together as it appears you have already done.
At the front of the wings are either woodend ( or metal ) rods sometimes called "dowels", or a piece of hard wood.
This gets inserted into the cutout at the bottom front where the wings go.
The proper angle of the wings to the fuselage is established by the "wing saddle" and the rear wing hold-down bolts.
The "wing saddle" is where the wings contact the length of the fuselage.
Drill the mount holes in the wing and put your bolts through this hole. This will PULL the wings torwards the fuselage and establish the proper wing incidence.
When you are done you will find that it will be less than what you have in the picture.
Please try to get help from someone a bit more experienced if you can.
This kind of thing is obvious to people that have put together many almost ready to fly airplanes, but it can be very confusing to someone just starting out.
Best of luck!
