Think ahead..there will be more parts soon
When I built my -4, I realized quickly, there are 2 stabilizers, 2 elevators, a rudder, 2 ailerons, and 2 flaps. I made a rack I copied from my old RC model wing storage system using vertical 2x4s screwed to wall and horizontal 2x2s screwed to the 2x4s that stored them horizontal and flat with minimum space between. I know it takes up more room, but if your going to keep building, it will fill up and you will be glad you have it. I don't have any pics handy, but its easy to figure out.
