thats good.. as for buying a twin...stick to the old faithful possibly affordable such as the duchess/seminole/seneca models
be prepared to pay quite a bit up front for the initial investment as well as a lot of maintenance cost and overhauls if the plane is flying alot. I dont see it as even being remotely profitable but I am completely guessing here as I have not worked the numbers. It would be great if it worked though. Barons either the 55 or 58 are quite costly and can be maintenance intensive in a training environment. Not a great training platform
