I have made a plane carrier out of pvc pipe that I have put on a plywood board. the pvc is only pressure fit together on between major components and pressed into holes in the plywood. this makes it easier to break apart the setup for changing the configuration for different types of planes be they planes with wings permanetly attached or removalable wings. I use bungee cord that I bought at a marine store and assembled myself so that the cord has very little tentionto hold it on the foam covered pvc pipe. the bungee cord attaches to the fram by using svreww in eyelets on the plywood board. the bungee has a hook on oneside and a loop that I can make a lasso slip knot to put over the eyelets to fasten down the ends. the eyelets also give me tie down points when the plane is to big to stick in a rack. the front of the plywood has a 2x4 in fron with two handlesto slide the board in and out of the truck. I bungee my flight box between the two handles at the front to keep it from slamming the plane. my truck bed is covered with and extang tonneau cover that rolls up easy to protect the plane from wind, rain and prying eyes of who might want to take it when I am not around. my tailgate locks so no casual lookers can see in. the cover remains on at all times and the plane slide out on the board
