I have being flying for only a year and still I dont feel comfortable checking a plane for the first time.
Each time a have a new plane (even if I bought it used) I have an experienced pilot to check it and maiden it for me.
I watched carefully and learn.
One of this days I will be ready for it.
So by no means you are ready to solo. I bet your thums dont shake w the sim, I assure you they will at the field.
