Yes that makes complete sense Floty, that's how I see it as well.
I know that if you put your flaps down during a fight with combat trim ON, you will have huge issues making shots. Combat trim and flaps don't get along very well, and if for example you're at the top of a rope and coming around on a target with the flaps deployed, the nose will tend to want to come up drastically, which makes "pulling" lead difficult when the stick needs to be pushed down in order to get the gun sights anywhere close to your target. Then a "push then pull" type of situation starts to happen and the net result is you are trying to simultaneously push the nose back down towards your target, then pull your nose along the target's flight vector line in order to "pull lead" and keep your firing solution.
Best option I've found is to make sure you turn off combat trim if you have it on just prior to deploying flaps for combat, particularly when I'm at the top of a loop during a rope, and while I'm pulling on the stick to come around on my target I'm also trimming my nose down like mad, as it's far easier to line up my upcoming shot with the nose trimmed to low instead of too high (see the push pull above) when I've got my flaps out in the K4 or most other planes I fly.
