I have been flying the 250-C30R/3 for 5 years now. I have flown it in civil and combat environments with zero complaints. the incorporated FADEC makes the engine very reliable and "almost" impossible to droop the rotor during flight withing aircraft envelope. when maintained properly it provides very rapid and predictable power and fuel burn. i wouldnt mind shedding some aircraft empty weight to take advantage of the power. but even running her at the 650 SHP limit, she runs smooth!
