Yes. I know about flux. I watched 10s of videos on how to properly solder wires. Thick, thin wires etc. .
I will get a flux for maybe 30 rupees from that mobile point.
Ye!!!
Speedybee BLS 50A 4 in 1 ESC!!
Ready To Sky RS2212 920KV BLDC Motors!
And,
These are F450 ABS redesigned landing gears.
All has arrived. Only the Pixhawk 6C Mini, GPS, and Power Module is remaining.
I should now start extending motor wires and then soldering it somehow into ESC. Then soldering ESC signal wires to Pixhawk ESC out wires.
But in Bluejay, we have an option of uploading custom melody into ESC. But I don’t see a buzzer here in the ESC. There are just tonnes of MOSFETs here with 8 SoCs. No buzzer.

Many things to learn for you (smile)
The ESC don’t need a buzzer it uses the motors to play music. And as a aspiring developer trying to figure out how this magic works.
I recommend to extend the motorwires by using good connectors somewhere between Motor and ESC( normally on the end of the original motor wires so that you can later mount and dismount the individual components on your frame

Connectors are a failure point. If they fail, you crash.
Either use good ones, or none.

if your not confident about soldering then use these motor connectors rather than bullet connectors

I am completely with you, but with the right connectors for the application (e.g. as @geofrancis shown ), assembly and disassembly in the event of a modification or even a crash is considerably easier and safer. I have not had any problems resulting in expensive errors with decent connectors in the last 50 years.
Unfortunately, I am still expecting some serious difficulties and even crashes with this project because, in my opinion, @RudrakshTek is not yet advanced enough to really handle this complex task on its own. The tight financial framework is an additional difficulty.

That completely surprised me off! Using motors as buzzers!
Yes I can use connectors, but I am wanting to have some soldering skills using this drone. Since I will prepare this drone and I don’t know when there will be a next one, so I think soldering wires will give some new experiences. Since I have got some hand in wire joining, I am somewhat confident. I will even try to solder some of my old broken ESCs and Motors. But there should be something to learn. Using connectors Is just not accepting the soldering challenge…
Yes I can/will solder!!!
Using appropriate connectors when advantageous is also part of the process.

Yes … your thinking like this is normal… What I can say is, I will make this Machine with patience. Finely checking all things, all joints, all screws, and mounts before the first flight.
No carelessness and odd behaviour with such expensive items will I do.
While, since Pixhawk has not arrived, I will not currently understand your experiences behind the word “Complex Task”. (But yes, making and setting my old gold unbalanced friend with Kakute and APM was like… Moderately easy…)
And, even if I somewhat find that my solder joints in this drone are not perfect, the shopkeeper of that mobile point knows soldering really very well. He will solder. But before him, I will try to solder there after practice.
No problem…
If you all really recommend of using connectors here instead of solder, I can also use them. 4 MT30 connectors only cost 200 rupees. So no expense.
That’s a design choice you need to make. Would you like to easily replace motors without disturbing existing solder joints? Then put some connectors inline. Would you like to reduce bulk and connection points? Then don’t.
Mmmmm…
I will prefer solder instead… Because I don’t think I will need to replace the motors in a short span of time… Because in this budget, in whole india, only these motors are available. Rest are very expensive. So… I think solder will be best. Hard and fast connection. Actually buying connectors is also a good thing … But for Soldering purpose, I seperately bought soldering iron, and then if I will go with connectors… Will just be an opposite thing… So solder… Ok?
Again, do what you want in this instance. If it’s a “dev” build, easy swaps are an advantage.
If you don’t expect to replace stuff, then skip the connectors.
The soldering iron is still required to make the connections on either side of the connectors, so it’s not really an “either or” situation.
Don’t ask for my ok in this case. It’s your choice based on your own expectations.

Just a glance on how this will look! (Excited like volcano!)
This is the image from the backside of drone. The battery will be like this at bottom, and double sided taped with the drone’s bottom. The ESC’s head part will be facing the drone’s right side like this:
(Photo from the left facing direction of drone. ESC’s head rightwards.)
According to this dia:
Motor 1: ESC S4
Motor 2: ESC S1
Motor 3: ESC S3
Motor 4: ESC S2
Also, If I have to extend motor wires, using soldering, how much AWG do I require? 16AWG?
Tomorrow I will be extending motor wires… So I will have to buy some metre of required AWG silicone coated wire from the electricals shop.
Enable ESC Passthrough Mode:
In Mission Planner or QGroundControl, configure your Pixhawk to enable ESC passthrough. This allows you to use the Pixhawk as a bridge to communicate with the ESC via the motor output ports.
~Chat GPT
When I will upload Bluejay, will I have to enable something like ESC pass through in mission planner?
Cable connectors are either crimped or soldered. Which version did you find in the example above from @geofrancis ?
These connectors are soldered and have a good solder cup. Soldering such contacts is considerably easier and safer than directly soldering two free cable ends for a less experienced solderer. But as @Yuri_Rage writes, you have to decide.
The cable cross-section should at least correspond to the cable on the motor, never smaller. The thicker the cable, the lower the resistance, the losses, the heat of the cable and the soldering points. But you probably already know that.
Please don’t use ChatGPT again, but rather use the extensive Ardupilot Wiki as has already been recommended several times. The right answer can also be found there. And for practice, there is no link from me this time
Geo Francis sir shared MT30 male female connectors which required wire soldering. I didn’t understood the meaning of “crimped” word in this context…
What does this statement means?
Ok… So I find a 16 AWG perfect for here. But for motor wires extending, I will like to go with soldering only. At least for this purpose I have purchased a soldering iron, flux and solder… Also, if I even feel like the joints are not strong, then that shopkeeper will do that for me. He has very good soldering skills. And I have joined nearly 30 wires till now, while the person at the mobile point teaches me. Nearly 15 were not perfect, but last 3 were ideal… More practise, more experience.
Remain assured. I will not let this drone crash due to wire joint failure.
And, ok… I will not use misinformating chat GPT again. …
Use it all you want, just don’t post it on the forum.

After some hard work, I found this ESC passthrough page there. There, it is written,
“Set “SERVO_BLH_AUTO” to 1 to automatically enable pass-through on all outputs configured as motors (e.g. SERVOx_FUNCTION = “Motor1”, “Motor2”, etc) for multicopters”
So, if we change this parameter to 1, we enable passthrough. But when we are finished configuring the ESC, will we have to again change this parameter to its original value? Or we should leave this parameter just like this forever??
