Abstract: A delayed-release suspension system for rubberband powered flying toys includes a wire-like hanger arm affixed to the forward end of a fuselage of an airplane, the hanger arm being inclined rearwardly at an angle from the vertical of 10.degree. to 25.degree. and provided midway thereof with a V-shaped notch. One end of a rubberband for use in powering the airplane has attached thereto a figure 8 shaped attachment loop, which can be manually positioned on the hanger arm astride the V-notch therein. Upon winding up of the rubberband, the loop adjacent the V-shaped notch will, because of the torque exerted thereon by the rubberband, rotate around the mounting thereof on the hanger arm until it reaches a position wherein the respective sides of the loop are braced against the sides of the hanger arm by the torque. Upon release of the rubberband powered propeller and subsequent unwinding of the rubberband, a delayed-release of the propulsion mechanism will be effected.
