Again; a Po-2 (even in Arcade battles) will literally not even hit half the speed that the racing Po-2s were capable of. The Po-2 will rip at ~120 knots and so it won't go much faster even in a dive in Arcade to prevent ripping. In comparison the racing Po-2s will hit significantly faster speeds level
To make a similar sounding siren you could do something similar to what the guy in the video did, possibly. You would probably need to experiment a lot to the get the right sound. I think it may be possible that the stuka's main propeller "chops up" the sound as it's diving, similar to speaking into a fan.
You're missing the speeds of the controls stiffening, and then locking up. Pilots in dive-bomb training, and in active operations sometimes crashed into the ground by diving too fast, and were unable to pull out of it. It's unfortunate, but not odd, if the plane is taken out of its capabilities. Try also shallower diving, if it's a long dive.
The JU-87 Stukas flying overhead are possibly from 1./Schlachtgeschwader 3 (SG 3) The unit was part of the Detachment Kuhlmey which participated in large battles of summer 1944, during the Finnish-Soviet Continuation War. When the Soviet Red Army launched its fourth strategic offensive on the 9th of June 1944.
People don't realize cheating on war thunder won't work very well even with aimbot, sure, no matter what you won't miss, but if you're aiming just so you can BARELY hit the enemy (that's what the script was doing in this video, it was aiming barely high enough to hit every) meaning that most of his shots are either going to be center mass (or L3XV7. 658814542167608265350
