Upon connecting a 12S lipo the ESC's LED blinks 11 times. "Series resistance too high"???? What causes this and its solution. A search did not come up with a solution. The heli's motor was shut off twice now with one minor crash. This Logo 600 has been used hundreds of times and now this problem has come out of nowhere. And goes away briefly as the ESC and motor can be activated again on the bench.

Is it a wire problem , connector (EC5), ESC. motor???

Thanks for the help. Ken

What ESC are you using?

Have you checked all of your solder joints?

Thank you for the suggestions. I did pull on the wires entering the EC5 plugs and one came out easily due to the fact that the wire was broken! This was at the junction of the solder joint and the solderless wire - excessive flexing over the hundreds of flights resulted in the failure.
