igus® products are used in this helicopter drone. The rotor blades are guided by igubal® KBRM rod end bearings with metal sleeves in the balls. This combination is precise and has absolutely no play. The whole rear jib was designed with bearings to rotate it around its longitudinal axis in order to isolate the rear rotor from vibration induced by the drive. Flange bearings made from iglide® L280 have been resorted to here. More iglide® L280 flange bearings ensure freedom from play with little installation space in the rotor head's driver.
