One thing that I have observed with wood is that the glue should not be the fast drying ones as it does not get inside the pores. That is the reason why carpenters tend to use fevicol. So while that may not be the right glue, I would avoid the 5min epoxy or instant glue on balsa

First of all before assembling the wing, Check the following
Stack all the Ribs together and check if all the ribs are in size, fit the spar in the slots, spar should be flush on top, otherwise need to sand the spar slot.
Use a clear polythene sheet of the plan, pin the bottom spar in place, using cyno glue this will save you a lot of time. You can use Quickfix/Allfix or any similar adhesive to fix the Ribs in place. Add the leading edge and check if the ribs are slotted in the trailing edge. For a flat bottom air foil, the trailing edge is pinned directly of the plan.
After building the two wing panels, Check the dihedral angle required and join the panels at the centre section using Epoxy adhesive only.
If you require any clarifications do write in.

In the photos you had posted it seems as if you are placing the trailing edge balsa in the place of upper wing spar. The lower wing spar was positioned correctly, but you positioned the upper wing spar at the trailing edge and you are placing the trailing edge in place of upper wing spar. Please correct this.
First dry fit everything i.e ,Wing leading edge, lower wing spar, upper wing spar, wing ribs and trailing edge in place as per the plan and hold everything in its correct place using T-pins. After checking that everything is square and correct, use thin CA glue to glue every joint together. Don't use fevical wood glue at all. Haven't you received building instructions manual along with the kit?.
If you had not received, then the best thing to do is to download instruction manual of any trainer plane kit from the great planes website www.greatplanes.com. Download instruction manual of ANY Plane Kit.
Read it and you will get a pretty good idea of how to build a balsa plane kit and what kind of glues are to be used while building. They are very detailed and like text books for model plane building.
BTW how much did the kit cost?

best of luck. Smiley

Please post in a picture of rib, it looks like the trailing is of 2 sheets one on the bottom of the rib and the other on top of the rib. The balsa sheets in the first picture could be for the center section of the wing.

 Dear Rajaram,

The bottom photo is the wing dihedral base.The square balsa sheet  pieces may be for sheeting the wings at the wing center or for webbing between upper and lower wing spars. It would be very difficult to advice without seeing the full plan.
As I suggested before download the construction manual of GreatPlanes Electric Sailplane Model SPECTRA Kit, you will know how to do it.

Regards
Rao.

In the image 23.53.55 you can see the wing corss section on top of the fuselage. The leading edge is diamond shaped, the two spars with webbing on the front and rear and sheet trailing edge.
Before starting the construction check the leading edge fits in the front slot of the rib, else need to sand the slot, the spars fit flush in their slots and the trailing edge sheet is flush with the rib top.
To start the construction of the wing, first pin the trailing edge bottom sheet on the plan, pin the bottom spar on the plan, place the ribs on the proper position on the plan.
There are two types of ribs R1 and R2, You can glue the ribs on the bottom trailing edge and the bottom spar in their respective places.
Now you can glue the top spar in place and add the leading edge to front of the wing, now stick the top trailing edge sheet.
You can  now start the webbing on the spars, remember to cut the sheets to fit between the ribs and grain of the sheet should be vertical.
The is not require between the R1 ribs, as the dihedral brace is to be added.
The R1 ribs which are at the center of the wing, need to glued at any angle to give a perfect joint at the center of the wing.
You can use cyno glue or adhesive like Quick fix All fix. Cyno flue will be instant and the other adhesive will dry in about two hours.
