Hey Everyone, I have been trolling the forums for a few weeks now, the information on this forum has been extremely helpful. Thanks. Ended up purchasing a DJI Phantom last week when the price dropped. Yesterday, I opened up my Phantom for the first time to inspect the electronics and see what was "under the hood". When I was re-assembling the Phantom, I plugged back in the compass and GPS (had to plug the GPS back in to the NASA-M controller) and immediately I began the pre-flight checklist to get back up and running. Compass calibration was successful (even re-calibrated the compass thanks to the DJI video) and updated the Phantom to the latest firmware (Naza-M Assistant Software v2.18, Firmware 4.0). The issues now seem to be that the motors are in some sort of "fail" state, they won't preform anything beyond a shudder. I briefly got a "error 29" from the software, but I couldn't find any solutions to the error code. I have included a link to a YouTube video I posted showing the issue at hand. http://youtu.be/KZPJjYKsyIs I would greatly appreciate anyone's assistance with this problem, I'm quickly running out of ideas.
