I was helping my friend set up his brand new phantom. Balanced blades, set up the software, and before we could do anything the software said we had to update to the latest naza which was just released. We did a lever calibration as well as the advanced IMU, which the software said wasn't needed but we did it. On the new software it took all of about 30 seconds. We then went to try to see if it would fly and the motor would not start. I have a phantom so I am pretty sure we did nothing wrong. Is the unit doa? We get flashing yellow that just won't do anything else. Is it bad to start up your unit for the first time after do a software calibration and imu calibration. Any suggestions. My buddy is dying to get the DJI up and running. By the way, the new unit comes with the throttle lever with a spring so it stays centered. We tried starting with both levers centered and both levers pulled down to the left. So what is going on? Any help would be great.
