A flying device which rotates as it travels through the air includes a body having three radially projecting vanes. Three blades or wings are pivotally connected to the three vanes. Each blade may be selectively and adjustably attached to an adjacent vane so that the blade projects outward from the body. When the flying device is thrown, the blades cause the aerial device to spin in a twirling motion. For storage or shipping, the blades may also be folded over so that they abut the body.
