I'll have a try.
The 'pretty good' pilot has now been promoted into an X-wing, facing 3 TIE/LN fighters. I'll actually roll dice for this one.
Again, the fighters start at medium range, at full speed.
Turn 1
Rebel
Not wishing to engage if he can avoid it, the X-wing peels off his attack run on the Imperial communication satellite as he picks up three TIE fighters unexpectedly heading out to intercept him. He pulls into a corkscrew, hoping to drop in on their flank without exposing himself to fire.
Evasive Manouvres
Gain The Advantage
Skill check: AAPP (Agility 4, Piloting 2) B (Handling +1, DD (Same Speed) - Result: Success, Advantage
Can't really spend the single advantage on much, other than 'notice an important detail' - he realises that the TIE fighters must have been vectored onto his position by someone with much longer ranged sensors, hence there is probably a heavier ship somewhere beyond the relay satellite. In a 'proper' game, this might be a boost die for someone else, which is a much bigger deal...
Imperials
The TIE pilots close in attack formation, jockeying with one another for the best firing position. They turn into a long, looping barrel roll to keep the X-wing in their sights.
Fly (closing range)
Gain The Advantage
Skill Check: APP (Agility 3, 3 Minions with Piloting), BBB (Handling +3), DD (Same Speed), S (Enemy has advantage) - Result 4 Successes, 3 Threat
Two threat can be spent on a Boost Die for the X-wing.
Unexpectedly braking hard in a Silurian Stall, the X-wing turns in to attack, catching the Imperial pilots by surprise.
Turn 2
Rebel
Closing fast, the rebel heavy fighter unloads his lasers at the TIE group before they can take advantage of their superior position.
Fly (Closing Range)
Attack
Skill Check: AAPP (Agility 4, Gunnery 2), B (Spent Threat), DD (Same sillouhette as target) - Result 3 Success
6+3 Damage - Armour 2 is sufficient for a kill.
The closest TIE is blown to shrapnel with a single clean hit as his two wingmen scatter out of the line of fire.
Imperials
The TIEs turn back in, weaving to throw off the X-wing's line of fire, and open up with their own lasers.
Evasive Manouvres
Attack
Skill Check: AAP (Agility 3, 2 Minions with Piloting), DD (Same sillouhette as target, ignore evasive manouvres), S (Defense 1) - Result: 3 Success, 1 Threat
6+3 Damage - 3 Armour takes off over half the X-wing's hull
A laser blast rips into the starboard wing, and one of the engines is running rough. Tough as it is, the Incom fighter won't take much more punishment.
Turn 3
The X-wing pulls a tight Koiogran turn, trying to throw off the TIE behind it, and fires on the Imperial's wingman, hoping to even the odds.
Evasive Manouvres
Attack
Skill Check: AAPP (Agility 4, Gunnery 2), CC (Same sillouhette as target, target and firer both using evasive manouvres) - Result: 3 Successes, Despair (failure and threat elements cancelled)
6+3 Damage - 2 Armour is a second kill.
Despair spend on upgrading the next skill check
A second TIE fighter is blown to pieces, but the X-wing's damage is starting to show, and the fighter is becoming sluggish at the controls.
Imperial
Closing, the last TIE steadys up and looks for a killshot
Aim
Attack
Skill check: AAA (Agility 3), B (Aim), DC (Same sillouhette as target, evasive manouvres), S (Defence 1) - 2 Success, 3 Threat
6+2 Damage - 3 Armour is sufficient (by only 1 damage) to cripple the X-wing
There is a static squeal from the X-wing's computer and the fighter tumbles end-over-end as its engines fire randomly before going dead. The TIE fighter loops around for another pass at the helpless Rebel....
That was very close - specifically, the last attack roll for the TIE only pushed the X-wing into critical damage because it managed to roll not a single failure...
Ultimately, fighters do die very quickly if they get hit. More than anything else, one-on-group fights end badly, because minion groups of fighters can take so much punishment relative to a PC in a fighter - unless you're in something really ludicrously upgraded, you aren't significantly tougher than one of your enemies, let alone 3.
