Now you need to remove these plastic coverings on the bottom of the drone. I recommend using a small allen key and inserting it into the screw hole as shown. You should be able to pop the plate off from underneath very easily.

Alternatively, you can try to use a plastic pry tool along the edges of the plate. However, I have found this method to be more difficult and far more likely to damage the plastic.

After removing the plates, unscrew and remove both of the screws indicated by the arrows.
