Not sure about He-111z and Gigant, but Mistel seems to be broken, or at least the Single Player mission for it is. I saw a thread over at SAS of somebody with that problem. I checked it and found same problem. I even tried that SP mission in stock 4.08 and it does not work, but at least you end up in the cockpit, just no control over it.

Supposedly, if you enable stock 4.09, it works, but I have not tested that.
