The BO-105LS has the same cabin as the CBS. They were only manufactured with the CBS cabin.
Brett. The LS is a fantastic machine for lifting and fire bombing. It will lift the same as a BK117. I have used them for EMS as well and it worked fine but try and limit your crew on board to 3. You start putting 4 crew on board and you soon run out of space. The rear facing co-pilot seat allows the doctor/paramedic good access to the head of the patient.
There was a BO105LS for sale at Bankstown not so long ago.
