I've been having an interesting intermitent problem. I recently disconnected the red lead from my motor when I did the heatsink mod, of course this is before I found out I didn't really need to. But anyway, I pushed the connection back together and everything seemed fine. Now about every 3rd flight i'm having a complete motor failure. Since I'm still learning to hover this means that it drops from about 5 feet. After that, I push on the two connections to be sure they are seated properly and they always seem to be, and then it works again. This has happened with both lipo and stock batteries and isn't due to low power in the bat. Any ideas? Bad connector? The connectors are perfeclty clean and seem to be in good shape. What up?
That is a classic symptom of a broken solder joint. I bet if you pulled the heatshrink of the wire will come out of one of the leads. This was a big problem in the original Axes and I've seen it happen personally to the tail motor lead/deans connector.
