Have you searched your question on the website search option? The thread below, which is the second thread in the message group, is all the info about buying a Skymaster. I would suggest that you review this info and then ask some specific questions about the aircraft. It would take hours to answer your question as written, someone like myself that has a great passion for the aircraft could go on for days but may not touch on all the things you are really looking for. The newest Aviation Consumer magazine features Skymaster but I was not impressed with their review. It may help you answer some questions though. Please dig into this message board because there is lots of info.
