Bah! WAY too much effort

! I'm so lazy, I just liberate beer/wine case cardboard boxes from the liquor store(they are more than happy to get rid of them), cut a "U" roughly the size of the fuselage in each end, and line the U with spare foam pipe insulation. Costs nothing more than the gas to drive across town for the boxes and a few scraps of pipe insulation I already had. Your solution is a bit more, shall we say, elegant, however.
