What's the best way to...

[kozzm0]

the fw-190 had hydraulic or electric flaps that could be set at full landing, or at a slight 15-degree takeoff/maneuvering setting. It didn't help much, but it had an effect.

You're right about the spitfire though: no combat flaps on that thing. landing, or nothing. Giving it a combat setting in BOP gives it an unfair advantage. In real life the 109f had a smaller minimum turn radius.
