Just making sure I'm not missing something. Is it OK to do the aileron actuator section, the roll servo installation, and pitot/aoa installation prior to closing the bottom wing skin. So much easier to access with it off. Want to make sure there isn't an unforeseen problem during the riveting phase of the bottom outboard skin. Planning on using Zip Tips as well and was curious what type wire and how much to run out to the wing tips. Still waiting to hear back from Zip Tips company with that info. Wire everything thru the grommets or run PEX thru the holes where the grommets are? What do you use to secure the PEX and how do you terminate the ends of the PEX or do you? Lot of questions...sorry. Thanks
