title_body: Drone tipping over when attempting to fly (possible accelerometer problem?) This is my first time building a drone, so sorry if this is a stupid question or I use the wrong words. When I attempt to fly my drone, it immediately tips over (link to video here: https://youtu.be/og8w9KjhzBI). I know its not a problem with the motors themselves because when i turn the motors on using Betaflight Configurator, they all spin at the same speeds. I made sure my accelerometer was properly calibrated through Betaflight, and have searched the web for hours attempting to find an answer to no avail. Any help would be much appreciated.
upvoted_answer: Some simple things to look for before we go deeper:
  
  Did you check that all four props are mounted correctly? (CW on top left + bottom right, CCW on top right + bottom left)
  With your props off(!), your drone connected to the Betaflight Configurator, and your control inputs neutral, are all three control axes all centered (at $1500$) in the Receiver pane?
