Here's an interesting question. Some of us have a particular aircraft in AH that we love to fly, or fly all the time, or whatever, and many in the community think it should be perked for one reason or another (i.e. P-51D, La7, etc.).
In my case, it's the P-51D. So the question is, what changes to the game could you see as validation for needing to have your favorite NON-perked plane become perked?
For the P-51D to become perked, I think the following
1. No more auto-retracting flaps on aircraft
2. Addition of K14 active gunsight
3. Removal of "Replenishable" WEP
4. Additional engine controls that on early war fighters were manually adjusted but on the P-51D were automatic.
5. Gun / Cannon malfunctions that can be caused by pilot (not random) error (I.e. Firing guns in very high G turns, firing when inverted, etc.)
