Jambo, when you flew a full scale plane did you push or pull the stick/yoke to cause the nose to pitch down? Push of course. This isn't any different. I've flown a variety of full scale planes and have never pulled the nose up to initiate a dive unless I intended to do it by stalling the plane first. (That doesn't count an aerobatic entry to the dive BTW like a 3/4 loop) Done those - fun.
