Are you really comparing a non SAS helicopter vs Gazelle and even one 7,692 kg vs 1.000 kg helicopter? Please, give real data and not your feeling to support your arguments. You can't compare these 2 aircrafts, they are completely different. You maybe don't like how it flies, but really, stop comparing these 2 because is nonsense. Sa342 is a very light helicopter so the intertia is very very very low comparing it with the other helos, its 1 to 7 in empty weight with the BlackShark even the Huey doubles(and more) its empy weight.
About the controls, mate if you KNOW that it can't move that fast don't do it. But if you have never touched a SA342 in IRL, provide at least a reference where we can see your statement is true.
