Hi
As a flight instructor for a long time now I would go with the larger Super Cub as it will allow out door flying on non windy days.
But you can fly one, once your used to it, in quite a bit of wind. They are tough enough to learn on and after it gets beat to death the guts (reciever, servoes, etc. ) can go into any number of scratch built planes.
The little bitty indoor job from HK looks like fun but may be harder to learn on...still for the $ go fly it!
