Flatlandmike, The hatches in the tail, are for the Tail Wheel.. I guess so you can tack CA to the blind nuts..?
Eveguy, are you moving forward with installing the CA hinges? I have mixed opinions of them. They are large, and plenty per control surface, but... I have heard bad news concerning CA hinges. I haven’t had a bad experience myself ( on 120 size planes ), as long as you drill a hole in the centerline of the slot and inject plenty of CA into the hole.
