have you tried:
https://www.aircraftcostcalculator.c...copter+EC+120B
$988 per hours is what they say, thought the number was going to come more in the $600 to $700 range
in the same calculator if you try the AS350, you get $1088 per hours, that is so much more helicopter for $100 more
not sure how they work it out it, seem to me that the Arriel engine of the AS350 is
much more expensive to maintain than the Arrius
