Any answer to post #169 would be appreciated. I really do thank all of you for your help. This is all very complicated to me and I am grateful for all your patience. But if post #169 is acceptable then I can go to Carr Hardware tomorrow and pick up the necessary components. I want to install all the major components on my flight box before I stain it. I installed a screwdriver set complete with storage rack on the backside of the box and once the terminals are complete I will begin staining the box hopefully by the weekend. Then I can go back to completing my Tower Trainer 40
