Mr. X99, Is the provision of a cheap and quick aviation service something you are promoting? I for one, am not interested. I have never been happy with aircraft which were obtained chaeply, and maintained quickly.
For those who have received quick and cheap training, it does not entirely surprise me that there could be trouble converting to a C 152. The 152 has to be one of the aircraft types most likely to let you feel what it is about to do, and give you the cues to correct for errors, before they become serious, if you have received appropriate training to recognize those cues.
Presenting yourself into a very well established, safety minded industry, as "quickest and cheapest" does not convey a good image from any perspective....
