I have just short of 900 hours on the Koala and know about operating in hot and heavy conditions and other situations. I love this helicopter because it can do all the things that our company wants from a helicopter:- almost 4 hours endurance for ferry flights and 7 pax capability when on location. 3 POB for 3.7 hours at 125 kts or 8 POB for 2.4 hours. 8 POB at 6800 feet at 35C. P&W PT6 a wonderful engine. Controls are stiff if you are used to EC/AS machines
