I have just completed a cross country in my 582 drifter 9 hours in total and she didn't miss a beat, yeah she might use a little bit more fuel than jab but I personally felt safe. When I fly I usually track direct, some people get scared of flying over heavy timber country but I use altitude for a bit better glide if necessary. An experienced 582 operator on the Darling Downs told me you will never break these motors they just wear out (this of course includes our maintenance schedules hey people). I was looking at buying a jab so I can go faster and piss with the big boys but my wife said why would you bother when you have a perfectly good airplane and flies well. At the end of the day my 582 hasn't let me down and I do regular maintenance to it, people say 2 strokes aren't as reliable as 4 strokes but in my opinion I would disagree, I've heard operators say the compare good 2 strokes with a turbine engine, they just keep running.
