Hyperspeed

To get on the Hyades cluster, make a treaty with the Fel
by visiting them regularly.
Make a treaty with the Cisisbeo by telling them about Fel
leaving and wiping out another race.
To destroy the Lutins use the blaster turret against their
fighters and then use kamikazes and fighters to take out their
star base.  When you meet Stentors use fighters to wipe out
their red ships.
With the Didnium send a guided missile to distract their
lasers and then attack quickly with kamikazes. 
When you fight Broodmasters use a fighter to knock out their
laser turret and then use a mix of kamikazes and main guns
to take out their fighters.  Don’t exort goods from the
Broodmasters as they give you a spindrive-activated bomb which
cannot be removed.
