Bind keys for 'Adjust Sight Control to Left' (increases wingspan), 'Adjust Sight Control to Right' (desreases wingspan), 'Increase Sight Distance' (increses aiming distance), 'Decrease Sight Distance' (decreases aiming distance) and 'Toggle Sight Mode (Auto)' (switches betwen 'Fixed', 'Fixed+Gyro' and 'Gyro' modes).
Set the Fixed+Gyro sight mode and try to do some maneuver. The moves of gyro reticle depend no your maneuver. This is why it was used. Let's look at the gyro reticle. If you use gyro sight, you don't need the fixed reticle, but IMO the best mode is Fixed+Gyro. Look at the picture below:
Here you can see Fw-190 (:lol
which will be hit soon. I am not afraid of saying it will end with PK. In the middle is a dot. It shows where you bullets or grenades will go. In the outer part of reticle you can see diamonds - they are very important. Sorry, not the diamonds - they are here only to help you with imagining the red circle. To make it simple we will call the red circle 'Diamonds'
If you set wider wingspan, the radius of the diamonds increases. The same thing happens whey you decrease distance. Increasing distance or setting smaller wingspan cause to the diamonds become smaller.
In real life, two methods of aiming were/are used:
1. Select correct wingspan, decide which distance will you shoot from (usualy convergency dist), set this distance, aim directly on target and hold. Wait until the red circle touches wingtips of target and shoot.
2. Select correct wingspan, aim on your target and keep the dot on it. Keep the red circle on wingtips of the target (decrease sight distance). Wait until you think you surely hit and shoot.
This gunsight is not suitable for TnB and snapshots - aiming with it is relatively very long procedure. With 6 .50 guns you have to keep the dot on target for at least one second and shoot. Strange things are happening after this time - Fw-190's are loosing wings, Bf's are exploding or catching fire...
