Helicopter rotor blade adjustment installation - for remote controlled helicopter models and having cylinder shaped pressure spring with adjustable length

摘要

The blade adjustment installation for helicopter rotors, preferably remote controlled models has the rotor blades turnable in relation to the rotor seesaw. The latter are fitted with rotor attachments in which the rotor connectors are axially supported and inserted both turnable and fixable. The walling of the pipe shaped rotor attachments (2) have two slots (3, 3') lying opposite each other which are offset against each other in screw shape with a guide bolt running through them attached to the rotor connector (5). A cylinder shaped pressure spring (6) is supported between the guide bolt (4) and the pipe shaped attachment (2) with its length adjustable during axial movement of the rotor blade.
