Didn't take any pictures of the construction phase on the left aileron, so I will only include one entry. Will get more details when I build the right side. The process was rather straight forward. On the control surfaces I have used Tempo zinc chromate primer. The epoxy is great for large priming jobs but for small jobs it is a pain in the ass to use. Primed the complete inside surfaces as well as the inside of the waterpipe counterbalance. Hope it will stick to that surface since there was no way to effectively clean it. All bolts were torqued to proper values
