On the lancaster: The prop blades on the right side engines cause transparency issues as they increase speed during engine start up. Most notable, the inboard prop blades cause the outboard spinner to be translucent in the small area that the prop blades overlap the spinner.
On the He111: While in the hangar, and while on the runway with engines off, during engine start up, and engine shut down; the propellers appear to be in the full feathered position. Not sure if this is how the real plane worked or if this is just a graphical bug in game.
