Over the past weeks, we have successfully tested the flight controls - spoilers, wing flaps and the air-brakes - that are built into the wing. These have been mainly functional tests along with load testing. The flight controls on our prototype are mechanical and activated directly by the pilot using push rods.

Despite their huge surface area (the wing flaps are the size of the entire wing of a very large glider), the flight controls are activated with almost zero friction, and operate with the accuracy of a watch movement over the entire 60 metres!

We remain on schedule for the first tests on the Dübendorf airstrip.
