If I have a way to action while stressed, does a green manoeuvre executed as a slam remove stress?

I don't see why it wouldn't. SLAM executes "a maneuver on your dial" and unless something says otherwise all the relevant steps of completing a maneuver still apply. That would include "check pilot stress". So green SLAMs should clear stess and red ones should add it.

Technically, Lancer-class with the Damaged Engine crit (turns are red) can carry Contraband Cybernetics (take one stress and can perform red maneuvers and take actions whilst stressed) and Burnout Slam (one use slam action).

The large ship can easily dial in a red 3 turn (or 2 turn doesn't matter), pop Cybernetics (taking a stress) and perform the red turn. She can then pop Burnout Slam, and do a green 3 (or 2) forward slam (clearing one stress).

The Lancer doesn't even need to have Damaged Engine if she starts with some stress on her.

Can't think of another scenario where a stressed ship can slam though.

Chopper crew on a K-Wing or any large ship with Burnout SLAM.

The better point is that a Lancer can be stressed at the start of its turn, pop cybernetics, do 2 4 straights, and end the turn more than attack range from where it was, and unstressed, which is really a neat use of cybernetics.

Cheers for the replies ... it answers why astromech carrying vehicles will never get access to slam
