Japanese Patent JPS5037912
Kind Code:
Y2
Abstract:
A device for automatically lowering and landing an electric model plane of the free flight type comprising an electromagnet securely mounted on a plane body and energized by a battery for supplying a motor for a propeller with an electric power; and a system connecting said electromagnet to horizontal planes hingedly mounted on the plane body and which includes a magnetic member rotatably held by said electromagnet and a tensile means fixed to the plane body. Said magnetic member is adapted to be attracted by said electromagnet against an action of the tensile means while the magnet is sufficiently energized by the battery thereby to maintain said horizontal tail planes in a horizontal flight position and said tensile means acts on the tail planes to shift the same into a slantingly raised position when the attracting force of said electromagnet is overcome by the action of said tensile means by exhaustion of the power thereby lowering and landing the plane automatically.
