    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.

    I'm assuming you want it to be affordable too. I'm not sure if you're really going to find what you're looking for. There are tons of drones that do not have gps and can fly in a manual mode, but when you take these features away it takes greater piloting skills to keep control and smooth motion. I'm not sure if inside a "large metal vessel" is the best place to start flying one.

    As for camera, I don't think you will find anything on a quad that is going to be great at low-light and affordable. Most people don't fly their quadcopters in bright sunny skies and not caves. Not to mention most low-light cameras are pretty pricey. I'm not sure what kind of project you're working on, but is it possible to instead try and add some lights to the quad to make it brighter instead?

    Yes lights are an option. Cost may not be an issue at all so all cost issues aside, anyone got any input into what they think would be the best way to go about it.

    Yeah disconnect the GPS on your pro 3.

    Yes but trying to initialise the compass is impossible where I need to calibrate. Too much metallic interference.

    It's not really about cameras are not really high or low light capable....it is a combination of lens quality and wide aperture settings and shutter Speed or FPS the camera then need to cater for the necessary film speed. If you play with the camera settings on a DSLR or your P3, you can see how to adjust aperture 1.8 or lower 1.2 this depends on what you have and what you need.
    Film speed settings upwards of 800.
    If you intend filming in a metal clad building ...I think you already found it will affect the compass / gps. The right camera settings and maybe some portable lighting can cure one problem.....and you could hire an experienced quad pilot to handle the flying. Perhaps if you give us an idea of the job and location, maybe one of the guys here may suit the job...

    Is this advice or a joke?
    If advice it's poor... GPS must be connected to start the motors.

    Not to get off topic about camera here, but you can't say a camera has nothing to do with low light performance. Sure 1.2 and 1.8 lenses let in more light, but when there is little light to be let in even those apertures have their limits. You need to then change your ISO settings. On top ISO larger sensors are just going to perform better in lower light and the phantom camera has a pretty small sensor.

    Bad wording.. the point I was trying to explain was that its a combination of shutter speed. "film speed" and lens aperture.

    Trying to explain the details and talking about ISO etc,. to a person who knows very little - is more likely to confuse.
    The guy seems to have a job and decided a flying camera will offer a solution - my take is that he knows little about quads or camera's and talking in terms of "low light camera's being expensive" IMO seems to indicate its a "specialised" camera dedicated to low light photography.

    I have taken ( 35mm film) photo's in my younger days when I was into caving... or "pot-holing" as it called in the UK using time exposure, and simple flash with small slave units. Do you think offering this type of "solution would have helped?? - ( Not knocking you.. just saying its easy to get technical)
    The fact is - without giving more information about the location and conditions of work... one can only offer a generalised reply.
