Im developing a search and rescue hexacopter drone

What would this do that a DJI drone can’t

I plan on having modules the can be swapped out for the need of the situation

Is it resilient against extreme cold and wind/rain

I don't think you are.

If you're asking for this level of help choosing components, you don't possess even 5% of the knowledge required to accomplish what you state above.

It's one thing to ask for help, but at your current level of experience and expertise, you're going to be essentially asking people here to design this thing for you, and sort out the software chain to pilot the thing.

That simply won't happen, I'm afraid.

Firstly, figure out why you want a hexacopter. Don't assume anything. Actually learn why you think you want six motors.

If you can rationalise that, you'll be making progress.

All I need is a few recommendations for the inner workings of the drone

I've been searching for a while on how drones work and I've been looking for Motors and circuits but I don't have the money for trial and error
So Im asking for help to find some components that could work for what im planning on making

[ornate bear]

From what I've looked into the hexacopter seemed to be a viable option against the harsh effects of the weather (the wind mainly) and for its superior stability compared to quadcopters

I also wanted it to able to bring light supplies

So you have an idea of the target all up weight for the craft, and what size props you're going to need then, right?

From the props, you can infer a rough idea of motor size required, and what size frame you'd be looking at. But, since you've done your research, you know this already I'm sure.

If you let us know what sort of numbers you've worked out so far, we can go from there 👍

Its getting late for me
Ill get you the numbers hopefully tomorrow
