Hey I seen that you can replace the gimbal camera on the mini 2 if something happens. Does anyone know of a company that makes upgrades for the camera and gimbal? Like something with a bigger sensor and better overall camera.
No its not possible..... Your upgrade path will be buying a new drone - Mini 3(out soon), Mavic Air 2 or Mavic Air 2S. At that point you can sell the Mini 2 or start building a fleet.
The upgraded drones will still use the DJI FLY app so you will find them just as easy to fly.
My advice would be to fly the heck out of the Mini 2 until you are very confident and competent with it, then move up.
