Finally crashed the bugger. Actually the battery suddenly died without warning and it did a forced decent - into a forest. Amazingly I found it (not stuck in a tree!) on the ground with battery ejected and laying 5 feet away. Considering how I have to battle the thing to remove batteries, I was surprised. But that tells me its was a big hot. No physical damage. Upon power-up, the gimbal got all crazy. From what I can tell, the gimbal arm to base was not aligned correctly. I loosened the allen stud and realigned it. I checked the two other motors for alignment, both were and still are correct. Both motor rod to step reading sensor things are tight. I used this thread as a guide: viewtopic.php?f=27&t=20514 I am very mechanically inclined and with minimal direction can usually figure things out (not bragging, just saying I am not a complete idiot! ) So after many, many searches and lots of reading I can say that everything looks right. But I still have the same issue. The ribbon cable appears to be okay. So besides the typical causes as in the thread above, is there anything else I should look at? While I have not flown it yet, since I want to fix the gimbal, everything copter wise also seems good to go. It powers and spins up fine. Motors respond to controls, etc. Thoughts are: • Ribbon cable did get damaged, just shows no outward signs. • One of the motor boards is bad. • Some internal damage to the drone. I hate to start another thread on this, but I have been through so many others I dont think those will help.
