If the propellers are spinning and drone is not lifting it almost guaranteed that the props are spinning the wrong direction. Usually 2 reasons for this:
- Props installed backwards (maybe even upside-down?)
- Motors reversed, due to wiring, esc config, or betaflight setup switch.
First things is to determine which way the motors are spinning.
Note: Most drones spin “props in” meaning they rotate towards the ends of the drone; but some are setup to rotate “props out” meaning the props rotate towards the center of the drone/away from the ends.
Once you determine which way the motors are spinning you can re-install the props to match this direction.
Let me know if this helps. Also posting a video would help troubleshoot as well.
