We just got a full Phantom kit for our high school media classroom. We cannot get this thing going, even after reading the manuals and watching the videos. What I have trickled it all down to is the transmitter not being able to be calibrated properly for everything else to to work. Specifically, the A channel during the transmitter calibration does not register whatsoever: left-to-right-horizontal does not do anything. All the others work perfectly (E, T, R). Is there a complete reset for this DJ6 or am I missing something? So, if "A" does not work, the copter will not turn on. The copter itself does work with the motor test while connected to the software (USB). Please help before we have to go through a major process of returning this. Thanks in advance!
