Eddie is right in his first paragraph; don't confuse the 135's OEI capabilities [which are very good] with its AEO, which at MTOM are much less impressive. Not sure where he gets his empty weights from, even though it's a DPIFR; ours is a police one SPIFR but I know the earlierl statement of UK HEMS ones being about 2100kg is fairly accurate - of course it depends on what you specify as an "EMS fit".
