Its weight is clearly lower compared with metal and in addition they are less susceptible to damages. Numerous igus® products can also be found on board: The proven plain bearings are used on the elevator and at the main and rear wings. Inside the airplane, a drylin® linear guide system allows moving of the accumulator during the flight to shift the plane’s gravity centre.
