My instructor only charges Hobbs time, so all pre flight and post flight are basically free. He has been a CFI since he retired from his f/t job about 8 years ago. I’m not saying I’m getting over charged or anything, I just know it seems like I am always over the allotted time compared to the syllabus. I know most of them are an hour to hour and a half. I enjoy my lessons and my instructor, just trying to figure out if I need to scale back, should I do 2 lessons a week at 2 hours each or 3 lessons at 1.5? Is the .5 hr twice a week as good as and extra lesson would be? With an extra lesson I would get an extra pre flight inspection, taxi, run up, take off and landing, but might have to cram more into each lesson being a half hour shorter.
