I'm sure that someone will sort this out for me. More years ago than I care to remember I displayed the British Army Lynx for a year. From memory whenever I pitched from a steep climb, (aiming at 90 nose up, but probably more like 80 on a good day) to 90 nose down, the aircraft had a tendency to roll(right I think but I can't be sure). I always thought that this was some from of gyroscopic reaction, thoughts ?
