These foamies are very intriguing, amazing capabilities and practice right in front of your face. Did you ever see the Pigi from Hobby Lobby? In the vid, right in the middle of a hover, they cut the power and let it hit the pavement on its tail feathers and fly it away. EPP is almost indestructible with the ability to bend it in half and it will spring right back to its original shape. I want one for practice as I don't care to build another UCD. Joe
