I'm buying into a Part 135 charter biz in the Midwest and we are looking at possibly buying a MU-2F. From what I hear they are tricky to fly. Is there any truth to this? How are they on maintenance and reliability? Any idea on what the hourly rate should be? Is it very hard to find a good shop to work on them? All comments from those who have flown or worked on the MU-2 would be greatly appreciated.
