This is exactly what happened to me. I have gone through 3 Firebird Phantoms and they all broke at the spot you mentioned. I talked to a manager at Horizon Hobby repair and he is sending me a prepaid mailing label to return the 3rd plan. After returning the 2nd plane I indicated I wanted a different plane that would not break. The just sent me another Phantom. It broke on the first flight. After receiving the 3rd plane back, the manager will determine what different aircraft they will send me.
