With a 152 or similar, the student can safely experience bad landings, at least up to some point. in a -10, less so, because the cfi will have to intervene sooner to protect the airplane. I wonder if a -10 primary student ever gets to see/recover from a bounced landing? And of course spins are off the table. Similarly, the instructor cannot let unusual attitudes get out of hand. It can be done, but generally with more hours. And a -10 owner who doesn't mind less than perfect landings. Finally, the student should not get the idea that all airplanes perform like a -10. If he/she needs to rent a 172 it may be quite a shock!
