Stalling it completely at the top of a rope is an almost guaranteed extended tailslide into the dirt. Keep a little more speed than you may be used to in other planes at the top of vertical maneuvers.
If you're ruddering hard to bleed E, it can depart flight occasionally if you rudder to the right. You can do this almost on command if you put it down around 120IAS and kick full right rudder in level flight, it will lose lift and start flopping like a leaf. It will not do this nearly as easily if you rudder left in the same situation. If you see it happen quickly enough, you can rudder hard back the other way and it will correct. You can almost see it 'catch' when the wings start flying again.
To recover from the tail first stall of doom, turn OFF the engine, don't just throttle back, and deploy gear. Full rudder either side and forward stick, try to get a wing pointed at the ground to rudder into to get the nose down, and you should gain it back. This seems to be about the fastest way to do it. Once the nose is down restart engine and retract gear.
As far as actually flying it, it doesn't roll as well as a 190 but it does turn decently at speed. Keep it fast, slashing attacks. 2x20mm and 1x30mm make snapshots work very well. It's at its best hunting bombers by far, but is not completely helpless against fighters. It uses the vertical competently but it's risky due to the stall. Again, keep a little more forward speed than you would normally at the top.
