Hi, I'm brand new to flying and was doing really well with about 15 flights (and only a few minor crashes), until by my own fault, a prop came off mid-flight (only about ten feet up) and my Phantom hit the pavement pretty hard. I got an error code 25 after the crash, and after a lot of reading, I carefully removed the Naza, did the whole "table whack" thing, re-assembled (I made sure to label wires and take pictures so everything is exactly as it was), did an advanced calibration, and finally a firmware update. I now get an error code 27. I attempted to calibrate the compass but the Phantom just continually blinks yellow and red. I plugged it back into the computer (got the error code 27 again) and I noticed that the Phantom wasn't responding at all to the controller when I moved the sticks around. The Phantom wasn't responding to controller when I got the error code 25 either but I figured it was a side effect of the crash and once the error code 25 was gone it would be fine. I'm really new to all this and would really appreciate some guidance. I haven't even sent my Hero3 up yet!
