I often wonder if there is a different model used for external vs. internal views, and that the internal model has rigging for flaps, aerilons, rudder, elevator, and the external view does not? Anyone notice in game if the aerilons, rudder and elevator move on OTHER aircraft? Usually I'm concentrating too hard on not getting shot down ;-) If not, it could be a complete model overhaul would be needed for each aircraft to set up the rigging to allow this. If so, then it's probably a much easier fix just in the film viewer.
Either way, I know I personally requested this too. +1
