Upair One - No MAV data

Are you sitting there with your UpAir One on the shelf because the motors just won't arm?  Well,  I have been there twice now!    No MAV Data, motors won't arm is my previous experience with sending my drone back to Banggood.  The only change that I could see was that the internal SD card was super-glued into it's mount rather than the silicone (RTV) that was as the original craft was delivered to me.

Well, after a crash, which was my fault after an override on a low battery RTH, my quad sat on my table for 2 months until I had an idea.  Sometimes heating a circuit board will  repair it.  I decided to take the heat gun to the SD card and viola!  After heating the SD card (still superglued in by Banggood) I plugged in the battery and tried to arm the motors and it worked!.  I put the quad back together and took it outside and flew it for the first time in over two months!

My supposition is that the reason the Bangood superglued the SD card in is that it's having trouble with connections in their SD mount.  It's not that it's working loose, but that the connections are poor or the the SD card itself is of poor quality.  I don't know, but the problem appears to be centered around the internal SD card.
