RE: wind?
As long as you fly with an instructor and with a buddy box 12 mph wind should not be an issue with the NexSTAR. I learned to fly with the NexSTAR and for the first several flights, the wind was a bit high, and it was about a 60 degree crosswind to boot. Just get it up there and learn to cope with it. You will be surprised how well you can do after you learn a few things about handling it in the wind.
