I made the mistake of leaving mine in the box for a while and now I'm on my 3rd week waiting for a new cowl. Make sure to unwrap and check the cowl for cracks and pealing paint as well as the ailerons for horrific covering job. On mine the ailerons were so bad I didn't even try to re-shrink them, I just stripped and re-covered them. Everything else looked good. Also, a building note: if you use the measurements provided for the slave rods to the upper ailerons you will not get full down travel on the lower aileron which will also hinder the up travel of the other side. Since the holes were already drilled when I found this out, I set up my ailerons for differential to alleviate the problem. There isn't a problem if you use 4 servos.
