What I meant by turning away from the side wind is that since Cubs have such a small vertical stab and such big wings, the drag up front is more than the drag in the back. Therefore, the plane will naturally nose away from a side wind and then go into a sideslip stall..
No. Except for gusts, the only wind relative to a plane in coordinated flight is from straight ahead. The wind does not blow against a plane from the side. For the same reason, a plane with a large vertical tail surface does not tend to weathervane into the wind in flight. (This has all been discussed at astounding length in the "downwind turns" threads. It is not controversial.)
Like others, I agree that the Goldberg Cub, though a fine plane, is not a good beginner's trainer. In addition to the disadvantages already mentioned (mainly ground handling), it's a floater, and so can be hard to land, especially if you have a small field. On days without much of a headwind, I had to slip mine to get it down onto a small field.
