The base where I work we share with one of those grats machines. They do EMS with 5 POB plus the patient. They are doing quite well, plenty of power even thoug the place is quite hot in Summer, the only problem seems to be too much power for the structure, they just had to change the tail boom for cracks after 700 hours.. .I think is great, they mount P&W engines.Good luck and go for it.
