Excellent advice Redwing! I had to experiment scores of times before getting gold. As you mentioned:
1. Do not "hide" behind bacta containers as the lasers/missiles will try to go through them to get to you. Attack from above as much a possible.
2. Time is critical to saves, don't mess around -- know what & when to shoot and destroy in order.
3. The V-wing is great for taking down TIE and Seerdon's ship, but NOT for the lasers/missiles around bacta containers -- they'll "go through" the bacta to hit your enemies.
I have great success with the X-wing on this level (much better than the N-1), but ultimately the V-wing was needed (for me) to bring down Seerdon within the Gold-level time limits.
