Hi Team, Just wondering with all this wealth of info on here could the above drivers give their point of view on which one is better,Good points,Bad points etc.Have trolled thru the EC135 thread but want a more up to date argument .Cheers
Nicest things about the MD is the cockpit logic and big square cabin. The worst things about the EC is the hover power margin, it's poor payload and short range. They have equally bad points (MD) and good points (EC). Neither do a really good job.
From the websites: MD900 Useful load 2900 lb Max cruise 135kt VNe 140kt Range 260nm EC135 Useful load 3200 lb Max cruise 138 VNe 145 Range 350nm On paper, HOGE and HIGE performance looks pretty similar. There's my contribution!
Hum ? which website ? EC135 VNE is 155kt and cruise speed 140 kt we have a range of 450nm on the EC135 ! with the T2i or P2i the payload and/or the range will be increased...
i don't have a lot of information about the MD900/902 ! we have only one EMS MD902 in France but we have 23 EMS EC135...
OK I'll come clean...............our 135 cruises at 125-130 kts with 9 bananas on the FLI and 2 hours 20 minutes is the best we have achieved with no fuel left in the main tank and 40/35kg in the supply tanks. That equates to roughly 300 nms. I would love to swop our's for the one Lima Oscar has just for those extra 50 nms. Hover performance is pretty lethargic. I won't give figures as there are too many varibles, but only to say that my experiences with 'limited power' now are very useful. Once at and above 40 kts it flys very well and the autopilot is superb. Silly place to put the Cat A switch but believe that this glitch is being addressed. With 7 pob and no luggage the range is about 70 nms/ 45 mins flight time which is pittiful. Luggage space is excellent and CG is manageable. We have a bleed air heater and no a/con as it was too heavy and assessed that we would probably need it only on a couple of occasions. An Agusta Grand would have been a better choice except that the TR is vunerable to damage being close to the ground in situations of off airport landings. And more expensive. So as a compromise we have the 135 with the harsh ride in turbulent conditions.
Dis - Mystery - could I suggest you do a search on this site where you'll find this subject has been discussed, in great detail, more than once. The only real difference in the last 6-12 months is that the EC135 T2i upgrade is now in the pipeline (extra 75kg / 20 mins endurance) and the 902 lost out in the LUH contract; admitedly not to the 135 but to its stablemate - built on parallel production lines with many similar parts and an almost identical cockpit.

Where's PAN, he's usually popped up by now to slag off the 902 From an engineers point of view the 135 is easier to work on unless you've got an Ambulance fit trim and then that can be a bit of a laugh to get out when it's time to change the Aris pots
