Mohammad-

You seem to more or less know what you are doing, but I was wondering, have you actually flown RC before? If not, this may be a bit of a challenge to fly for the first time. I speak from experience, because I crashed a few planes trying to teach myself to fly before I got help.

Given your desert flying conditions, you may want to bite the bullet and pick up the larger wheels from your LHS.

Have fun!
