Just completed my build, still have to complete the install of the electronics and setup rates and throws.
I tried Tac-Foam this time instead of Welders because Welders turns yellow with age.
I did not notice in your build instructions where you actually hot glued the servos, maybe I missed it. I did that just before installing push rods.
I noticed that the aileron push rods were a very loose fit in the clevis and there was a piece of heat shrink tubing in the hardware bag that was about the length of the two white inserts for the thin push rods. I cut the heat shrink in half and used one piece on each end of the aileron push rod, shrunk it, then placed in clevis and added CA.
I normally use a small piece (about 1" x 1") of BlendTerm on the hinge line at each end of all the movable surfaces. Apply a little Welders (or Foam-Tac) and while still wet apply the BlendTerm. This helps prevent tearing at the hinge line.
I have not cut the slot for the 600mA battery yet, will do that after electronics are in final position. My best guess is that it will be in about the same position shown in your build log.
