One additional question. Playing with mission planner, i lost the original configuration of thé apm. Any chance to reset. Do you an configuration file available?
We do not have a copy of the original configuration.
I have been able to reset properly the APM and seems to be OK when usb is plugged on computer. BUT a new issue pop up… no way to start APM just with LiPo. Battery is charged, a sound is emitted when battery is plugged, but LED is not flashing as if no power came into the APM.
JUst for information I changed nothing on the hardware neither touch the wires. From outside all look fine.
Any idea.
The connection your Radio module could have damaged the board internal voltage regulator.
The sound you hear come from the motors?
Yes sound is coming from the engine.
How radio module could have damaged the board.
I received the copted for Xmas. it has been bought on your shop the 16/12/2015. what to do if the board is damaged? I have the “Facture”.
Since the Radio module was connected wrong, it could have damaged the internal regulator inside the control board.
Can you post some pictures?
I will do tonight.
Which kind of photo do you need. overall? detailled?
we can’t see nothing from outside but no problems I will do what you need.
Of the wiring coming to the flight controller mostly.
Have you tried to reset the board from the start ?
Which LED is not flashing exactly ?
using mission planner I did click on Reset to default.
Since then no LED (big one, small one by transparency,…) are flashing when on LiPo
but all are working properly when plugged with USD
You might want to take a look at the LED settings in Mission Planner.
copter.ardupilot.com/wiki/nav-leds/
Ok but I guess that at least the red LED from the RC receiver should be on! And it is not neither.
And what about the internal LED not flashing.
But I can and I will try this evening.
No other way to do an hard reset?
The Receiver take power directly from the ESC internal regulator (BEC).
If it doesn’t power it could be that no power go out of the ESC’s so first check the LiPo and fully charge it before trying again.
This is already done. Last try I did, LiPo was fully charge, and was working.
I know it because with usb, I was able to Arm the copter and motors were working. The sound out of them was pretty good, normal.
We took one X5 from inventory to upload the Mission Planner setting file.
]In Mission Planner go to: CONFIG/TUNING - Full Parameter List /:m]
]On the right you will have a “Load from file” green button and use the file in attachment here/:m]
]Click on “Write Params”/:m]
Let us know if that help
STORMrc X5 - APM Settings.zip (1.84 KB)
Ok thansk I will do it tonight. I will keep you aware.
Shall I do a reset before? pushing the reset button ?
This should change all settings so no need to reset. 
Now I tried and nothing changed.
Here below is the file before I upload the new one.
What’s the next step?

Have you looked inside Mission Planner to confirm all sensors are working ?
The LED is one thing, but it should not avoid you to fly your UAV if everything else work.
