I edited the thumbnail to say that the machine is updated.

Since the update to Unity 5 (Besiege v0.2), the balloon on each drone attaches to the starting block rather than the top of the flying spiral, which changes the handling. To make it handle more like it did before, I lowered each flying spiral by a block length, to lower the center of mass.

Also since the update, Dr. One showed an increase tendency to flip over backwards under acceleration, so I lowered the speed a little to make it easier to control.

Finally, I move it forward slightly, since it just barely clipped the back of the bounding box.

I fixed one of the button mappings to work in the xml file type.
