Abstract:
An airfoil blade (40) in a powered toy aircraft (10) has a body (42) with a cushioned edge (54, 56). The body has a first end (44) adjoining a hub (46), a second opposing end (46), a forward edge (48), and an opposing trailing edge (50). The cushioned edge is attached mechanically to the body and extends along the forward edge so as to form a cushioned leading edge (54) of the blade or is attached along the second end to form a cushioned blade tip (56) 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.
