The screws should require a 1.5mm hex key and there are 10 of them. Once the screws are removed leave the arms in the unlatched position and at the arm openings press in on the top shell and pull out on the bottom shell to unlatch the small plastic clips on each side of the arm openings. Then unplug the GPS from the Mainboard and mark the connector it was plugged into (or take a photo before disconnecting).Yes I know there are a few screws to remove, I think I found the right tool. The screws are very small. I thought I'd leave the card hanging. I'm waiting to drain the battery that I had charged for my tests in the last few days to drain a little, because I don't know how long I will have to store it then and then I will start dismantling.
Thank you for your advice... I also hope very much that this will solve the problem, I will not fail to report it by posting a message here.
Thanks DoomMeister for these clarifications, I found the right tools to remove the screws, but I have not started yet, I am waiting before the call of the person to whom I must send it to have the price, the deadline and address; he must have forgotten me today, I'll try to contact him again tomorrow because in France it's starting to get a bit late. I will keep you posted.The screws should require a 1.5mm hex key and there are 10 of them.

Pack the top cover with GPS module so it can’t be crushed during shipping.
Anxious to hear if this works.
Salut Antony, Steeve est de bon conseils et quand j'ai un souci je fait aussi appel a ses services.Hello DoomMeister and 7Cyclops; following your advice, I tested leaving the drone on for 1h20 in an open area. It certainly helped, but I still have the same problem for the motors starting, beeps and lights flashing red. I also tried to start the motors by disabling the GPS and removing the propellers, same thing. I'm not sure but the GPS doesn't seem to be in question. And I wanted to launch a compass calibration to see, I always have the message "check for geomagnetic interferences" which is displayed as soon as I launch it. Steeve Lebon, a Yuneec specialist in France left me a message that I had to magnetize the compass by leaving the drone stored too near to a magnetic source; it is true that it was stored 50cm from an electric radiator, I don't know if a radiator can have this effect on the compass, but it does not seem impossible to me. What if this is the case? Is there a solution to demagnetize the compass or should it be replaced (if this is the problem and if this spare part can be found on the internet)? Thank you for your opinions. Anthony
Hello DoomMeister. I did not remove the GPS card from the cover and found that it was not upside down following the intervention. As I wrote on my previous comments, the calibration always flashes green at the end; only when I want to start the motors does it flash red. That's why I tell myself that it may be a calibration other than that of the compass that is the problem... I thought maybe the RC calibration since there were failures at this levelDid you remove the GPS board from the top cover when you sent it to be demagnetized? If so, did you place it back in the same orientation? The wires should be toward the rear of the cover.
When doing the compass calibration have you ever been able to complete it successfully (all motor LED’s green) or do you always get the red flashing motor LED’s when performing the calibration?
It sounds like you will need to clean the Stick Potentiometers.I just looked, with each attempt to start the motors, I have the message in the history: "NOT ARMING: one or more RC sticks not centered"
The stick issue and the geomatic interference issues are not related. There is hope the Geomatic issue may have been resolved, or at least mitigated, by your earlier actions. Once the sticks are performing normally, we can better address any remaining issues.I have (I had until yesterday, it could come back) also the messages in red in the history during the calibrations of the compass "Check for geom. interf."
I just looked in RC monitor, I actually have a problem in J4 which is very slow and does not exceed 50 or -50; no problem with J1, J2 and J3Do you mean you see no response in "RC Monitor" when you move the sticks? If so, it may indicate a firmware problem that has been seen a few times before.
I would advise opening the back and cleaning with the stick gimbal removed from the ST16S. This could also be an issue with the connectors for the wiring harness of the gimbal so removing, spraying with plastic safe contact cleaner, and reinstalling may help.I just looked in RC monitor, I actually have a problem in J4 which is very slow and does not exceed 50 or -50; no problem with J1, J2 and J3
