Also, just a random point, not sure if anyone did this before but if you go at suuuper high speeds (M 2+) and then just dive down to sea level, if you are still well over 1.5, the aircraft will start to wiggle REALLY badly and start yawing from side to side... it's the rudder CAS trying to correct the flight but it keeps over correcting and eventually it will get so much that you'll just about depart or black out lol. If you turn off rudder CAS however, the problem goes away. Just an interesting note on the 15's FM
