mCPx board problem???

[Davy Crockett]

I was flying my mcpx yesterday, few circuits and happily buzzing around in the spring sun, until motor slowed and landed after 2mins of flying. Fitted a charged battery and now all that happens when I throttle up is blades spin for split second then nothing, and blue LED flashes slowly

Its on its second board, which horizon have been great by replacing 1st one FOC

Anyone had this and what was the prognosis??

I had the exact same thing happen the other day and it was due to the wires breaking on the battery lead plug.
Snipped off the old connector and soldered on a spare from a charging harness and has been fine since.

That makes sense as 1st time I plugged in a new battery, nothing happened until I wiggled the wire

Thanks muchly!!

I have a V1 MCP-x which does this when the battery goes low, so it seems to be a Deep Discharge Protection cut-off system for the battery. Cure is to rebind but I now always coat the plugs/sockets regularly with contact grease to make sure the connections are low resistance. I used to find on some batteries that the plug/socket was warm after a few minutes flying indicating the connections were high resistance causing voltage drop.
