Safety and Training
Part 2 in a series on evaluation of aircraft controls, learn how to check your controls in flight for appropriate balance, trim, and resistance. If you can't explain to your mechanic what's wrong, they're very unlikely to be able to fix it! (If you missed Part 1, check it out here.)
Soft-field take-off isn't just a theory. Make your instructor take you to a local grass strip. There's no other way to really understand how the soft-field take-off really works (and it's fun).
If you live in the San Francisco Bay Area, Frazier Lake is the place to go. It has a grass strip and a parallel water runway. Just please read and follow the rules regarding use after a rainy day.
In your primary training, you were taught that you must correct for wing drop encountered in a stall with the rudder. The reason is that once an airfoil has stalled, further increasing the angle of attack (such as by dropping the trailing edge of an aileron) decreases lift (rather than the increase in lift usually resulting from an increased AoA), so correcting with aileron shouldn't lift the wing and should lead immediately to a spin. This is all true. But you maybe tried correcting with aileron the first few times, and it worked. Read this to understand why.
