Paul,
If I were to guess, it looks like techs used in this fighters BFC are:
- Beam Fire Control 50% Range 24,000 km
- Fire Control Speed Rating 3000 km/s
From there it looks like you used ship BFC instead of fighter BFC, 3X range and 50% tracking speed. This should net a BFC that is 1.5hs has the characteristics posted.
Here are some things to keep in mind. Tracking speed used is based on which is greater ship speed or BFC tracking speed. BFC tracking speed is limited to base tech tracking speed for non-turreted weapons, with the exception that fighter BFC base tracking speed is 4X racial tracking speed. If weapons are turreted, then BFC tracking speed would only be limited by turret tracking speed.
With that said, the tracking speed actually used by your example fighter should be 18,292kps not the 1,500kps of the BFC. In other words, you had it correct.
