So this Go Go Bird seems to prefer turning left. Right it does on occasions. So I let others have a go to try to figure out why but it left us all confused. Still we had fun on the way. Managed to crash into so many things....

These birds are not fully controllable but very interesting. Thanks to Ray, John, the other Ray (not enough room on the video), Dom and the others.
