As I mentioned in the other thread on this subject, the prop effect is far, far too dependent on fps and not totally dependent on prop rpm as it should be. Simply turning to a fps reducing scene (ie towards or away from London/an island in the online maps) will induce flickers in the prop, without any change in rpm - that fact makes each persons impression of the prop different, as we all run different resolutions, detail settings, monitor refresh rates etc. So, I'm guessing we'll see this discussion over and over again.
So, to recap CLOD repeated discussions:
Tracers! - Too thick
Props! - Might be too flickery at low rpm, hard to tell since its different for all of us!
Landing! - Ground too forgiving!
AI! - Disastrously good roll rates, painfully addicted to barrel rolls!
Etc.
