Also when you are ready to start learning to land take the speedbrakes off before you (the student) gets the plane below thirty feet or so. The Nexstar will fly slow enough that your flight controls will lose effectiveness without the prop blast blowing across them (thats what happened to my first one). The speedbrakes block the prop blast from the control surfaces.

Good Luck

P.S. This won't be the last plane you crash but you can learn from the crashes too.
