Not sure what part to replace, i imagine it hit the exposed camera parts so that leads me to think its the camera and not the gimbal assesmbly on the inside of the drone. am I wrong? has anyone else experianced this?

Hi, I'm sorry to hear about the accident. Please kindly contact our support to start a case and send it in for diagnosis: https://www.dji.com/support. If the drone is still in warranty period, the local team will arrange data analysis after they received the package. Thanks!
