Not a single word of encouragement there about having a C210 online (or any plane for that matter!). Why you might ask? Simple really it will cost you more to have/own it for hire than what you could possibly make on it, money & mental health wise!. I used to hire one & many other types many years ago (C210 $100 & C182 $60 P/H ) like a lot of us did in here but to own one you would have to be either very rich & or just plain dumb !In those days it was someone elses problem if we returned with a busted plane.
I wouldn't own a plane if you gave me one. I know that's a contridiction in terms with ref to this thread) Best to hire it, pay the cost at the end of trip 'cause it's a known quantity & there aren't any surprises & then after thr fun sleep like a log at night. Because doing it the other way round you better have a good comfy pillow !
You simply pay for someone else to have all the fun, is this what you want AS?
