Re the heater, I had Dart South 45 heaters in both my 206's and can thoroughly recommend them. As with any bleed air heater there is an amount of noise but it did the job in our -8C snowfields, plus kept the screen clear on a humid day
Crashworthiness? I turned one into a convertible and walked away after pulling hard enough to snap the collective, and the seat absorbed some but not all the impact. Luck of the game?
Reliable as can be, only let down once when a starter solenoid failed. Costs predictable within 5% which is as good as you'll get with 8-900/hr pa, lots of stories to tell
