There is nothing wrong with the plane, but if you are learning it is not a plane to learn on. Cubs have a very short body, they are difficult to handle on the ground and have bad tendancies at take off. I have a .40 cub that I do not think I am ready for yet, and I am pretty good with my trainer.

If you are brand new to the hobby, that plane is best left hanging up for a while while you get the hang of a trainer.
