A livery of the rescue helicopter Christoph 28 (CHX28) operated by ADAC Luftrettung which is based in Fulda/Germany. Currently there is the aircraft with the registration D-HUTH. Of course this is not a permanently used aircraft because they switch their aircraft pool over and over.

Installation is straight forward as usual:

Open the downloaded ZIP-File and place the EC135_ADAC_CHX28 folder into your community folder. 

Obviously you'll need the latest H135-Mod Update in order to use it correctly.
