Scifi,
Models are an excellent way to get to learn about flying. However, it is necessary to understand that though the aircraft can be scaled up or down, air cannot. Consider that the propellers on your powered models probably turned at 8000 to 16,000 RPM, where the prop of a Cessna (for example) would turn no more than 2800 RPM. Similarly, the power to weight ratio of models is very different to full sized aircraft.
You might want to do some reading on "Reynolds number", and scaling. When you factor these together, the differences will become more understandable. If you do some reading about the Ercoupe, you'll find that its design tended toward the stall resistant characteristics you speak of with the models.
