General question, I am building a great planes ultra sport 40+ and am about to start covering it. My concern is that I will not be able to get the aileron servo wiring through the wing after it is covered. I thought I could probably feed a piano wire through the area and pull the servo wire through. Another idea was to put a string through it and feed it through after covering. The last thought was to install the servo and then cover, but it seems this would interfere with the covering. Any thoughts or past experience with this. Thanks.
