Completed the right wing, installed the flap servo, glued both half with 30 min. Epoxy.

I noticed the flaps torque rods were loose when I held the flaps against the wing and pushed on the rods, they just didn't have enough glue on the rods/flaps, I solved that by poking some small holes on the underside of the flaps with the exacto knife right over the torque rods and added thing CA to it, problem solve, now the flaps are very solid.

When gluing the two half first I dry fitted them, end up shaving the corners of the wing joiner to have a loose join, when gluing it it was much easier to slide together, the center join is perfect no gap, very clean.

Now moving to glue the tail feathers, I noticed that with the travels recommended in the manual I couldn't get it to travel without having the elevator in the rudder's way, my solution was to cut about 1/4" from the bottom of the rudder to get enough clearance for the feathers to travel all the way to the recommended distances.

I couldn't upload the pictures of the construction earlier because the wifi at home wasn't working, I'll try tonight again.
