If you are hanging by the horiz stab, you may want to put something long and somewhat stiff on the leading edge for the bungees, cords, etc to rest against. I believe what daroc is referring to is that it may put an indentation in the wood. If you put something stiff on the LE it would spread the stress over a wider section and would prevent the cord from 'digging' into the LE wood. This digging could result from the weight of the plane pulling down on the cords that are holding the plane by the horizontal stabilizer.
You could use something like the core cardboard tube from inside a roll of toilet paper or paper towels. Cut it in half lengthwise and place it on the LE of the stab. This way the cord, bungee, whatever will rest against it. You could even use the foam material that a lot of guys use for the field kit stands, etc.
As some have mentioned they have never had any problems hanging their planes without these, but I would do this if I hung mine from the horizontal stabilizer.
I hang mine from the ceiling (tall ceiling so we don't hit our heads or damage the planes) using hooks and straps. That way I don't have to disassemble them. The straps are wide and wrap around the fuselage and cowl.
