Adding "Tractor Capability" lets you mount a tractor beam where it was previously unmountable. To "use" the accesory, buy a tractor beam - the mount that you added the capbility to will be available.
Turrets automatically include a tracto beam. To use it:
- Target the object you want to tractor
- Fly to within 1000m of said object
- Press F9. This resets your flight computer so that 0 set speed means you are moving at the same velocity as your targetted object.
- Move into your turret by pressing CTRL+F1
- Press g to cylce to your tractor beam
- Point the turret at the target and fire. You may have to go back to the cockpit to reorient the ship so the target is in the field of fire of the turret (i.e. place the target at the rear of the ship if you have a rear turret.
