PURPOSE: A swash plate of a model helicopter is provided to reduce abrasion between an upper plate and a lower plate, thereby preventing the swash plate from being separated despite long time use. CONSTITUTION: A swash plate of a model helicopter includes an upper plate(10), a spherical bearing(20), a lower plate(30), a thrust bearing(50), a fixture(40), and a ball bearing(60). A through hole(11) is formed on the center so that a rotation shaft penetrates the upper plate. A screw thread is formed on the inner circumference of the through hole and is connected to a main rotor to enable rotation. The spherical bearing is installed between the through hole of the upper plate and an outer circumference of the rotation shaft. The lower plate is placed on a lower side of an upper plate. A coupling hole(31) is formed on the center through which a rotation shaft penetrates. |
