I am flying in a C150, mostly. The running costs are $80/hr. Let me tell you, its a rocket ship. Why I saw 105 mph the other day. The Gulfstream that pulled out in front of me yesterday was anxious to take off and I gave him some extra room so I didn't run him down.
Once I am finished with my PP I plan on getting my taildragger endorsement. I may consider doing my Instrument rating as well. Who knows. This is a lot of money in training I am talking about now.
