If this risk should start to repeat itself, and the parts will not arrive on time for the second time and the third time and so on, the risk's influence should be minimised by finding new and more trustworthy partners to work with. | Considering the delayed components, at first, it is possible to transfer this risk, meaning that the responsibility of delivering the components on time will be on the supplier.

| - | The rigid sail has two main components: wing and tail. The purpose of using a tail is to control the direction of the main wing using a servomotor and because the tail is much smaller, there is lower consumption of power. This method is much more efficient if it's compared with no tail wing, that is using a servomotor that requires much more power to change the direction of the wing. | + | The rigid sail has two main components: wing and tail.

| - | The biggest stepping stone in the whole of the building process was the error in the first solution of the front steering. When the frame for the sail car was completed and put on wheels, it became obvious that the car is really difficult to steer with feet and it basically does not turn at all. The front wheel turned to either left or right steered the whole car in the same direction only a really minor amount. The reason behind the problem was discussed and found, that the fork of the front wheel was attached to the frame with a too little angle. Therefore, the wheel fell too much to the side while turning, and the forces coerced the wheel to fall even more to the side, rather than going back to the neutral position. As a solution, the team consulted with the supervisors and it was agreed, that it would be more reasonable to build the steering system in a way, that the front wheel would turn to either side, more like a normal car wheel, not tilt to left and right, like on a motorcycle.\\ | + | The biggest stepping stone in the whole of the building process was the error in the first solution of the front steering.
