If the red wire came to you common with the black wire, there may be a QC issue involved. I'm sorry to hear of your misfortune.
Thank you Tim for your reply. Yes the power module came just like this from 3DR. I sadly did not inspect it before hooking it up to the rest of the hexacopter :-( But who would think that something like this would be overlooked in the factory?
But just to be safe: the red and black cables should not be like this on the 3DR power module, right???
I bought one several months ago but I've yet to even look at it. So I will.
Maybe you should check with the store about this mischief.
Thats really a bad mistake, whoever soldered it...
I did inform 3DR and they are sending me a new power module. Can't wait to get it so I can finally "lift off" :-)
