Geistware,
Look at Mike's graphic. You'll notice that with the 6 point star there will be less throw to the front (less down), which is what you need for aileron differential.

Griffin,
You may be curious as to the reason for less down, or aileron differential. In some planes (trianers quite often), equal down throw will cause "adverse yaw", which means that the plane will "yaw", or the nose will turn in the opposite direction of the "roll" input given with ailerons. The reason it happens is; the downward deflected aileron, while increasing lift, will also increase drag. The increased drag slows that wing which results in the plane's nose swinging towards the slower wing.

For example, you give left aileron command which will cause the plane to roll left (the direction of the intended turn), but the right aileron drops, which CAN cause the right wing to slow a bit, thus causing the nose to swing to the right.

By making down aileron a bit less you can over come the tendency towards adverse yaw.

Does that help at all?
