I hope someone could help me with this: I really want to get people into GA and in the air, so I was very happy to learn about the sport pilot instructor option. It will cost no small amount getting from non-pilot to CFI-SP with LSA. My question is, just what kind of airplane can I use to instruct in? Can it be any plane I am otherwise authorized to fly? Or must it be a S-LSA? It appears there are conflicting opinions. Any help will be appreciated. Thanks!
