Looks like two popsicle sticks stuck together...kinda like t' "helicopter" all o' us made growin' up; however it takes surprisingly big motors. Begad!  Was quite a hoot t' fly and very entertaining. I'll be bringin' this t' most o' me launches. Arrr!  Added a spiral red pattern t' one side and black stripe edgin' t' t' other...looks AWESOME!
