Airplane Restraint/Hold-Down
Two pieces of 1/4" aluminum rod, bent 90 degrees about 2" from the end, and about 2' long.
Work them into the ground- the 90 works as a sort of "push handle". Also helps when pulling them out. Use foam for padding.
Push them into the groung so they are just wide enough to hold the tail, be sure to point the "handles" forward or you can remove the horizontal stab when vigorously picking up the plane- don't ask-
