I feel like I just answered this, maybe on another forum. I unfold / fold the wings of my Kolb every flight. Takes 10 minutes each way. I don't tow it every time though; I generally keep the plane in the [enclosed] trailer at the airport, and only bring it home occasionally when I need to work on it (in the winter, I keep it it at home and tow it to the airport for the occasional flight). At the airport, I pay the outdoor tiedown rate, a lot less than hangar rent (not that there are any available hangars anyway).
