My experience teaching kids is that they get bored pretty quick. I teach to a program that takes them to the point of handling emergency situations after they solo. Most beginners freeze when they get out of control. So I take them up real high, roll inverted, shut the engine off and put it in a spin, then give them control back. Thats done more to check their response. I give them about 4 or 5 seconds to gain control before I take it back. 99% will freeze, even the adults. But after a few times of doing that, they develop an automatic response. Its just practice. You gotta remember, after you solo, now you're dangerous. Practice practice practice. Learn to use the rudder, it makes a bad landing approach a non-event.
