Can you name some planes which drop nose when putting flaps down? I'd be interested.
The Piper Cherokee I took flying lessons in, for one. Many low wing pipers exhibit this behavior, actually.
I'm just your run-of-the-mill private pilot, but I've gotten a kick out of the commentary on the flight model regarding pitch / flaps on the dcs forums, as well as here... It seems many that I assume have never flown an aircraft have a strong feel for how they should fly. My experience in literally all of the three types I've flown has been that dropping flaps results in considerable pitch down (dropping flaps increases the camber at the rear of the wing significantly).
