Here is the rack I made from 1X2's and 1X4's. I lined the rails with foam and made a pull handle from nylon rope. I secure the plane and wing with rubber bands over the top secured by screws on each side. The weight of the whole thing keeps it in place. Only time I had a problem with it sliding around was on the freeway on a windy day, otherwise, for a trip across town to the field at 45 mph, it is secure.
