location? under the the wing mid-chord

If you mean the fowler dive flaps, you have to assign a key for the airbrakes and it's only on the L models.

If you mean "how do I activate the airbrakes on the P-38," then first make sure you're flying either the "L" or boosted L model. The "J" does not have the butterfly-type flaps. Second, you have to make sure you've assigned a joystick or keyboard button for "airbrakes" in the "Controls" menu.

If you mean, "where do you actually SEE the airbrakes deployed externally on the P-38," then watch the trailing edge of the wing aft of the cockpit on the "L" model(s) while you deploy the brakes. The flaps extend downward. Hope this helps.

Pretty sure the dive breaks and fowler flaps are two separate things. The dive breaks just extend out into the airstream and cause allot of drag...the fowler flaps are just regular flaps but instead of just dropping into the airstream to create a little extra lift they actually extend outwards as well which creates a bigger wing area.

Correct me if I'm wrong http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Word of warning on the drive breaks in the P-38L...if you deploy them, don't forget to retract them later. They will slow you down very quickly!

That's correct IceFire.

In short dive flaps were used to create drag to limit the speed on the aircraft to prevent overspeed/overstress while Fowler flaps are not used to create drag, but create more lift at slower speeds (by extending to create a bigger wing area and leaving a gap between the parts to accelerate airflow to make it stick longer to the wing), reduced stall speed and slower landing speeds.

The P-38 never had dive brakes. It had dive flaps. Drag was not their purpose. Their purpose was to change the airflow.

Sweeltly explained, Goya! ~S~ ! In fact the Dive Flaps for the P-38 were designed to keep the airflow under the wing "flowing", and not "break" thus creating turbulence and the consequent compressibility. They were not designed to be used to tight the turn in combat, BUT, many pilots did actually use them in combat, opening them for a second or two to allow a better airflow and prevent speed stall.
However, this was NOT a standard procedure.
