Falling back on sub-sub system design

8 Hours before the presentation we where afraid that the brushless motor wouldn't deliver enough power to lift the hovercraft. We looked back at our sub-sub systems and knew it would be powerfull enough, so we continued working. In the beginning we didn't succeed lifting. We knew the brushless motor was strong enough so the only thing that could be bothering was the rotor. We opened the rotorbox, used some magical glue en fitting and tested again.

And what turned out? Hell yeah, the sub-sub system design was correct.
