Using "creative packaging" I've squeezed both my BUSA 1/4 scale DRI and Nieuport 11 in my Ford Focus station wagon. Those along with support equipment, a small suitcase and a popup shelter on the roof. I did this when I attended Rhinebeck a few years ago. I had to drive alone, of course. The planes are not modified with removable tails or two piece upper wings. I'm able to fit up to a 100" one piece wing in it.

A Subaru Outback would do the same and it drives better and gets better mileage than a van.

I'm working on a 1/3 scale NII now and have no idea how I'm going to transport it! I'll probably need a small utility trailer and/or build it to break down to fit the wagon.
