All of the Sticks are descended from the original Ugly Stick. It was one of the best trainers of all time.

Flat bottomed airfoiled trainers only became popular again because they were easy for the ARF makers to make. They are probably the worst designs to learn how to fly on.

Thirty years ago, everyone had made the jump to symmetrical or semi-symmetrical airfoiled trainers. It is a shame to see things de-evolve in such a manner.
