I just finished a KYOSHO P40 Warhawk that has retract gear in the wing. As I do with most of my projects, I whipped out a couple of airplane stands to hold the fuselage while I stuck the sucker together. After it was all done, it dawned on me that transporting that thing to the field was going to have a problem. With the wing off, the fuselage doesn't transport easily. There is nothing to keep the fuselage from rolling over except the tail feathers, and they're not designed to work like that.

The obvious answer was to make a carry cradle for the car. It took about 10 minutes and cost almost nothing. I use half-inch foam insulation board and cut it out on the bandsaw. It's dead simple to custom fit it to the exact task. It's cheap enough that you can make 'em for every airplane that has some special shape.
