There is no detent or any other support for correctly inserted card, you just need to push the card until it stops, look at the example below.

The microSD card cover is somehow loose and can come off right in the middle of the flight. It is recommended to fix it with piece of tape.

Settings file

All camera settings can be accessed and changed by altering the configuration file [thumb.conf] located on the SD card.

GyroFlow stabilization

Download Gyroflow from here:

Open (or gust drag and drop) video file and gyro motion data file into the GyroFlow software.

Select the RunCam Thumb lens profile for barrel distortion correction.
