The EC 145 is really a BK117C with a 135 "front end" on it. EC did a great job in removing the control closet and running the controls through the centre winshield fairing.
I flew one a while ago and actually preferred it to the EC155. 8 pax and a totally move around and flexible interior make it an excellent small offshore, big EMS type machine. Almost a 412 competitor in my opinion. Cost is about $5mUS with SPIFR package fitted.
