La-9

This is my first model of a real airplane, and it's also the highest quality and most complex I've ever made. Don't judge me harshly for some inaccuracies, I'm still learning. I'll tell you a couple of interesting things that happened during the creation of this model. I tried to repeat exactly all the characteristics of the real version of this aircraft. In the process of setting the speed (the original speed of the aircraft is ~180 meters per second or 690 kilometers per hour), I got a funny bug if I accelerate the plane more than ~ 200 meters per second, it starts to accelerate uncontrollably. during turns, the speed reaches 500 meters per second, and in a straight line it reaches 900. during sharp turns, the plane's tail is torn off. by the way, I made several recordings.
P.s. I do not know if the bug works on this version of the aircraft, try to increase the power, if nothing happens to you, then most likely it will only work on an earlier version of the aircraft.
