I received a RTF TH40 trainer that I purchased for my son, have not flown it yet, but I am very dissapointed. The wrinkles in the picture attached are nothing compared to the way this plane came. I hate to have him wait again but I am surely gonna call and see if I can get this thing exchanged.
This is a normal and ongoing thing with film-covered models -- it will keep re-ocurring throughout the life of the plane. The fix is to shrink out the wrinkles with a heat gun (a model covering heat gun, not a hair-dryer). Learn how to do it, 'cause you will be doing it from now on, regardless of whether you build it yourself, or buy it pre-built.
