flying lessons
Personally, I think once a week is minimum and twice is better....if you can't afford once a week save up and do it when you can. Find a CFI you like, first of all. Secondly, like was mentioned before, it's nice if they will be around long enough to see you finish. Most CFI's are looking to move on, though, and you can't really hold that against them. It's really not fair to judge based on how long they have instructed or been at that school....sometimes you don't want the guy who's been there a long time if they haven't moved up the career ladder for a good reason. Some young, fresh CFI's are the best...it's just hard to tell. If you can find a retired professional pilot or one that is instructing for fun on the side....that could be a good bet.
