Thanks Hasse, as a scout this is usually not the behavior of the enemy's escorts. They pretty much will attack us (at least one of them), while the 2-seaters run away.
Banjoman, I've noticed this tactic as well and take advantage of it, if we are higher than them. I will ignore the brave one that faced us and go for the coward. By the time the brave pilot catches up to us we're usually done with the coward and can have a proper dogfight.

The connecting rod out of my brain, my brain,
From out of my arse take the camshaft,
And assemble the engine again."
