ABSTRACT:
An airfoil blade in a powered toy aircraft has a body with a cushioned edge. The body has a first end adjoining a hub, a second opposing end, a forward edge, and an opposing trailing edge. The cushioned leading edge is attached mechanically to the body and extends along the forward edge so as to form a cushioned leading edge of the blade or along the second end to form a cushioned blade tip or both. The body is formed from a first resiliently flexible polymer plastic material. The cushioned edge is formed from a second noticeably softer material such as an elastomer.
