You are correct. Even though I tested the battery and it checked out, I bought a new battery and the thing came to life. It still has some weird things going on. It flies but all of a sudden it goes crazy and either spins or one rotor stops completely. Then you reset it and it flies normally, for a while. It does not always go crazy but sometimes it does. I am in the process of trying to figure out the new symptoms. Thanks for your continued help.
