RE: Constellation's Pitch change w/flaps
In answer to your questions, the gear didn't seem to cause any pitch change, and the flaps pitched the Connie nose down a bit on deployment. It was a bit more sensitive to pitch change with airspeed changes, with it pitching up a bit as speed increased. It was very neutral to power changes in regard to pitch change. It was only a couple of clicks of trim to offset the pitching in any case. Frank built in the full size incidences to be faithful to the design, but taking a degree of positive off of the wing should reduce this trait. Again, it was nothing to worry about, a very easy airplane to fly.
