This update adds the following...
Rain particle effects! Rain is now visible outside the helicopter when it is raining with suitable audio effects.
Updated the HUD horizon line so it is easier to gauge when your flight vector is indicating level flight. This was actually included a couple of updates ago but I forgot to mention it!
Fixed the D-30's centre point so now you should be able to target it a little easier.
Flares no longer cause damage to your helicopter if you happen to hit them.
