Why not do the set up at home? Run the engine at home? Leak check the fuel system at home? Radio set up at home? Instead of doing the set up at the field? Nothing worse then going to the field and finding a minor grounding item that you waited to check until you got to the field? Then you have to pack up and take it home to fix? There should be nothing to do to the plane when you get to the field for the maiden. Should be able to fill it, start it and fly. Good luck!
