Hi. I recently bought a Dji pro 3 but need info on other types. Is there a drone I could fly without requiring compass calibration or gps, but giving me gyro stabilised assist and accurate flying whilst inside a large metal vessel? I know it's a strange question but need to know if it's possible. Is there a drone/quad copter on market that would work or would I need to design/build from scratch. Any help or info greatly appreciated at this stage. Oh, also needs high definition video and stills with lo light capability. Thank you.
