Notice there is no hangar cost in this estimate. I think 500 a month would cover that. You can see that just owning one yourself is very expensive. The instructor wants to be paid and the owner would like to make a little profit so $400 an hour for an R44 (fuel extra) with qualified instructor is not out of the question.
