Technic Panel 1 x 5 x 11and came in abundance on the 2009 FLL field mat (there was a giant bridge in the center, that was made up of them, my FLL friend had 2 kits, and we obtained a free one from our regional tournament. He was kind enough to let me use the yellow ones, and I was able to supply most of the red ones. They are very versatile, and if you asked me what my favorite technic element, I would probably tell you "The bridge plate!"
