I didn't say the warrior would not float like a fast frisby over a hot asphalt parking lot. I said that you don't particularly need to know how to fly to get a license in a Warrior.
No adverse yaw to speak of. The plane basically files itself. Really well designed. Just too easy to learn to fly and miss those little details about flying.
I have run flight schools and seen the difference. The C-150 is one of the best trainers around. It will demonstrate those little quirks of airmanship that are necessary for a properly trained airman.

It is possible to be taught how to fly and miss these things in a C-150(2), but less likely than in a late model Piper.

One of the most difficult probelms is a low time instructor who flew exclusively in Pipers and got his instructors rating (all except the required spins in a C-150) and was taught by one of the same being turned loose on the aviation world.

The question would be do you want to learn to fly airplanes or an airplane. If you want to learn how to fly airplanes you need to learn how you fly them, not how they fly themselves.

Don't get me wrong the PA-151(181) etc are good airplanes, but I don't believe that they should be used for initial training.
