Really… As I read 3/4th of methodic configurator nearly, yes… it feels like I have a lot to do in the software part also… After assembling the whole hardware. Heavy heavy names of .param file make me somewhat hesitated.
Since I want an “Optimized vehicle” and I am “patient” , I will have to carefully read and do each and every step. As everything is first time for me. Pixhawk 6C Mini got late in delivery due to some problems. I didn’t found a nice 16 AWG wire at any shop, so I ordered 3m of it from robu.in .

For soldering, which tip do I require?
According to my search,
Chisel tip for soldering motor wires to ESC:
And conical tip for soldering ESC Signal wires to FC ESC out wires:
Some people also recommend bevel tip for thick wire connection.
Is it ok?
You’ll likely get use out of them all. Very generally speaking, use the largest one that fits the available space (within reason). A bigger tip will transfer heat faster, which usually results in a better joint. But smaller components will not afford the space to use the large chisel tips, so you’ll need to use the smaller ones to avoid bridging pins or overheating components.

In documentations, I read about an interesting sensor called “Time of flight” or “Lidar” sensor. It is used for obstacle avoidance, but when I checked it’s price, some of them of long ranges costed more than 5,00,000 INR!! (5905$) !!! Later, i read that it is also used for creating 3D maps of a given area, but Still ! Isn’t 6000$ much just for a drone sensor! Some of them of extremely good quality costed 20,00,000 INR! Why will somebody use a 20 Lakh rupees sensor in their drone! A whole 7 seater kia carens come in this price!
You are still not getting the kind and large usage of drones.
As you still explains that these sensors can be used to create 3D maps.
Such function is used to make high resolution commercial maps and the drone is used as it is much cheaper as a real man carrying aircraft.
Or it is used for seach and rescue operations and creates new maps after a disaster. So in all these cases USD 6000 is only small amount compared to the benefit the drone has.
You always only look with the eyes of a low budget toy drone.

I use some LIDAR hardware from TeraBee that’s less than $100 US. Not all rangefinders are so expensive. Those that are definitely have their place in specific, high precision work, though.

Start with some sonars if you want to use proximity, you can pick up sr04 sonars for very cheap, they aren’t great sensors but they should let you experiment with proximity. A better module is the GYUS42 but they will be more expensive.

Cheapest outdoor 360 lidar is probably the LD06.

Most Cheap lidars usually have low power lasers so struggle outdoors in bright sunlight.

Don’t worry about the expensive LIDAR sensors. Yellowscan, Riegl, SwissLidar, (even DJI), all of those are used for data collection. They weigh (a lot) more than your drone. Cost (a lot) more than your car, but they produce high resolution data. They are not for range finding or obstacle avoidance.
Benwake, and Lightware make less expensive lidar for positioning the drone. Great products but their good ones aren’t cheap either. I would agree with @geofrancis’s advice and try a sonar sensor first. I’ve also had bad luck with cheap Lidar sensors outside.

Haha. Yes really. Actually I am new into the field, so, 6000$+ being paid just for a sensor is really fascinating. Just also got shocked when I saw many videos on how Lidar works. It’s really an advanced things! Creating real accurate 3D maps of large places by just using light! And such advanced mechanism running inside a lidar! I read the whole documentations on connection of a 360° lidar, single direction lidar, SONAR with autopilots.
Actually I already have 2 HC SR04. As 2 years ago, I interfaces them with Arduino, and raspberry pi 4. Just 4 months ago, I interfaced HC SR04 with Arduino UNO R4 wifi. I will surely connect both of them to this drone for obstacle avoidance.

But one thing, if I fly this drone in an open park, then the HC SR04 will not have any work to do!? So maybe, sonar sensors might be used for the drones meant for indoor flights? Just like the flow sensors are used for positioning indoors, where GPS signals do not have strength?
You can face one down and use it for assisting altitude hold. So when you hover it will be able to maintain a much more accurate altitude above the ground as the rangefinder lets it measure where the ground is. as long as the rangefinder has a fix on the ground It will follow the terrain at a fixed altitude, so it will start to climb as it goes up a hill or descend as it goes down, you usually need to have a long range rangefinder or be at low altitude for it to work.
For proximity use outdoors if you’re just flying in an open area they won’t see much, but you can still experiment with the proximity.

have you got a crimping tool and connectors, I will make your wiring much simpler if you can add your own connectors.

Wow!! Really amazing view! The drone automatically increases its altitude as it moves up the slope! Hope my drone will also fly that stable… And I will also send it on a mission… My drone flying above the Chambal river near my house, sending nice live footage…
Life becomes easy…
Sorry… Out of budget currently… Even the soldering iron and flux and solder which I have, was given to me as a birthday gift on 26th of November by my sister…
Sometimes I feel how richly poor I am… Spending 33000 INR till now on this drone project, still out of budget for necessary tools…

Please, please @RudrakshTek stay first with the system as it is and bring this safe to fly. Don’t use any area with obstacles. First learn to configure a simple drone correctly. This alone will be a great work for you if you get it without chrashes.
After that you have enough time and hopefully again a small budget to learn the next steps.
Face to your neartime project and decide what is necessary to realize this.
More background information is always good but don’t leave your track

Yes… Remain assured… As I previously also said, till Pixhawk is not delivered, I am reading documentations, and there, certain things I am getting to know, which are really fascinating. So I discuss them here… I also know, firstly a good flight is important, then these life risking missions can be performed by drones… I am just collecting the information, not I will change my track…
And, Please, never say “please” to me like this! Just order me. You are nearly my grandfather’s age and you should never request me like this. Just order and end. A teacher never requests his students to complete Homework.
I think if I don’t want to listen your advice, I should not be here.
I saw some kaga developer conference conclusion video. I saw many developers were there, but Yuri sir, amilcar Lucas sir were not shown in video? @Yuri_Rage @amilcarlucas ? Don’t you went in the conference? Showing new advanced exciting ideas like all these people? So much fun will be there! Showing our ideas in front of many people!!
I just think, are all of the developers there, graduated from a university? Especially in UAVs and robotics? They embed AI, ESP32 like things in drone! And are never slightly feared of experimenting!
I participated remotely.
Many of those giving presentations have doctoral degrees in related fields. It’s a talented bunch!

So what was your idea which you showed when you participated remotely?
And, @Juergen-Fahlbusch , @dkemxr , @geofrancis , etc are also very talented, aren’t they developers?
