wing stalling on purpose?

[Avimimus]

Too low a velocity and a larger cross section generally characterise high speed stalls and can allow an opponent to make a slight roll, kick the rudder (thus rapidly moving the nose sideways) and fill you with rounds. Basically, its suicide.

That said I have deliberately "departed" (ie. high speed stall/spin) in order to escape an opponent who is at a very close range (too close to be able to effectively follow me without winding up in the same situation).

I also regularly induce a partial stall of one wing in order to enhance the aircrafts roll rate (usually this is possible only in one direction due to torque and is only possible in some aircraft) and to bank the aircraft at speeds where traditional controls are ineffective (eg. at the top of a rétournemant/hammerhead/immelman type maneuver). I do this all the time and normally induce them to "warm up" prior to combat.
