I had the pleasure of doing a few hours longlining in the 407 on the fires earlier this year.
Very responsive solid feel absolutely loved it.
I thought the start procedure though was overly complicated compared to the French Fadec systems and I was concerned about the problems and consequences that could arise if they wern't correctly followed.
I know I may receive some negative responses to this but the french stuff seems to be more pilot proof.
Another problem was the temp limitation at around 1000' asl which another 407 also working in the area was also experiencing.
Both operators tried everthing to rectify the problems changing all the usual associated components etc without any success.
Our Lama's (originating from late 50's technology) lifting capabilities and reliabilty are significantly better than the 407 I flew
Fly safe
humbly yours
