I'm afraid the 4-in-1 receiver might be damaged, E-Flite claims to test them all first so you think they would have caught that if it was the case.
Your right, E-Flite "claims" to "test" fly them. I am sketchy to whether or not they really do. They may just fire the engine up and say, "yea, we "test" flew it, it works."
