I broke it

Well, I broke my Eachine 250 Racer. Need new props, one arm and motor. Also the LED front light I think. I bought replacement parts for this repair and the future.
My only question is this; what type of soldering would this all require? The only soldering I speculate that is needed will be soldering some wire to the motor and then just screw and zip tie everything else like how it was stock.
Any advice will be appreciated.

You will need to solder the motor wires to the ESC and the ESC to the board. The headlights are plug in unless you ripped out the connector. Openpilot is unsupported, So use Librepilot which looks just like openpilot. I think you can also use betaflight or cleanflight for CC3d board as well.

Thank you for all the help. I have gotten it to fly now, however, the drone wishes to drift right now. Keep in the front right arm was fractured in three areas, so I super glued it. The front right and back left props were bent and actually I accidently melted the back left a tad because I was too lazy to remove it when I was soldering. >_<
New props? Replace arm? Tune?

I tried glue, epoxy and other things but i could never get it to hold together for even 1 flight the way I fly. I would guess with glue the angle and pitch of the arms are not exactly the way they were. So it might cause some drifting. Try downloading the latest firmware in librepilot. I dont know for sure but it might correct the gyro and accelerometer. Also correct the level. Other then that you could try adjusting the trims on your controller.

I learned the new arms are the way to go. $6.99 amazon prime, 2 day shipping. For me it just wasnt worth all the time removing, gluing and assmembly just to have it break the very next flight. Maybe you will have better luck.

Well, it flys fine. I tried full throttle, pitch, and yaw. It just wants to drift right. When those parts come in I guess I'll just replace the fore arm.
I just find it odd that it wants to drift right.
The last thing I can think of is that I used screws instead of hex key fasteners and the heavier ones are mostly on the right...
If my controller has trim adjustment on the fly, that'd be awesome. My drone was RTF so I have no idea what button does what. XD

If I have to replace the ESC and motor, do I need to tune it? Also, two broke off completely It fell apart while in flight.
How do I know if CW is left and CWW motor is right?

If your quad worked fine before crashing, you may be able to just put new motors and esc's on without any tuning. You'll just have to calibrate the esc's but it's pretty simple

When I crashed my 250, the FC and PDB stack went askew causing mine to drift right as well.
Plugging in my CC3D to LibrePilot and making sure the frame was absolutely level, I re-calibrated and saved.
Now it flies the way it's supposed to.
Highly recommend when you replace any part, whether electronics or hard bits like frame, arms, etc, to reprogram the FC.
Especially the electronic bits.
I've also gotten in the habit of plugging it in at least once after each flight session (2 or 3 batteries). But that's just me.

It depends on the flight controller you're using, so I'm going to guess it's a CC3D board.
Try this Youtube video for information.
You'll need to know exactly what flight control board you are using in order to know which software to use to communicate.
Naturally, you will need a computer (MAC or PC), a USB cable (usually one with a mini USB connection) and the appropriate GCS (ground control software).
I use LibrePilot for my CC3D boards. There are others, but LP seems more intuitive for me.

Google your quad and you'll find tons of information. Especially on YouTube.

Good luck.
