the FAA rules in the USA for experimental aircraft is that I may buy one I may even take flight instruction in one, I may give flight instruction in one, but i may not rent one out for flight instruction or even private use rental. To do that the airplane must have a standard airworthiness certificate. So that leaves the high dollar new LSA like a CT, or an older design like the ercoupe, champ, or taylorcraft.

I didn't make the rules just have to follow them. If I had been the CEO of Cessna when they came out with the Light Sport Rule I would have begged bribed, whatever the FAA to make the Cessna 150/152 named or somehow able to operate under the Light Sport Rule, In my opinion those are the perfect light sport airplanes.
