Rotor head for ultra-light gyrocopter

The rotor blades on this gyrocopter rotate about 400 times per minute and oscillate to a maximum of 30°. They are mounted on two plastic bushings and two thrust washers each made of iglide® G300. The rotor head uses four plain bearings and thrust washers. Other bearings absorb the rotary motion of the brake lever. In addition, two igubal® self-aligning pillow block bearings are used in the steering system.

The low weight and freedom from maintenance were the main reasons for using igus® bearings. The pillow blocks were also used because they are vibration dampening and compensate for misalignment.
