I've completed the center wing section. The TUBIG thread was extremely helpful here again since the manual and plans did not clearly show how the wing joiners attached. I made a couple of simple changes. Since the kit provided me with an extra center rib and doublers i added them to add strength. You can see this in the pictures.

I must say that the TE sheeting is extremely delicate and easily broken. i found myself adding glue to fix some cracks i created. the other thing that got me is when i was sanding the bottom, prepping for the bottom skin, my table was not 100% clean and i made lots of marks in the top skin. This mean i will need to do lots of filling and sanding. it does not take much to dent the skins at all. The servo is mounted, i used a futaba 3151 servo for the flaps.

To get the bottom ready for sheeting I remembered a few good hints from TUBIG. That the bolt plates raise above the ribs. I used pieces of sheeting and kept sanding the rib notches to get the bolt plate close to even with the sheeting. Then i made a template of the bolt plate and cut out a smaller size hole in the sheeting. You can see where the cutout did not align over the bolt plate. (pen Marks). I then adjusted the cut out and got it really close. I need to take pictures of the final product (center section).
