This doesn't really have anything to do with aircraft. All it presumes
is that the engines are numbered from left to right. I know this is not
a safe assumption, but I plan to solve this problem later. Basically all
I am trying to do is be able to simulate the practice of steering with
the throttles on the ground:
Turning right:
O
| O
| | O
| | | O
| | | |
Turning left:
O
O |
O | |
O | | |
| | | |
Using this on arbitrary aircraft for yaw control in the air will be fun,
but most likely non-productive.
If I get an aircraft that doesn't have it's engines numbered right I
will be able to turn it off (there will be an intensity property that
will be set to zero for this)
