Each wire you solder can be checked with the multimeter to see if it has a proper conductive joint. & not a dry one.
The ground is open right through the system. So if you go black to black & it doesn't make a sound, somthing is up.
From my knowledge, maybe the gyro doc can comment. But red is the same, but can have switches where the circuit ends until powered on or switched on.
But it's mainly the esc & pigtail.
If you go red to black & it beeps then you're about to burn money & time.
You have shorted somthing. If you cut wires @ your desk or whatever, always blow the quad off before a lipo plug in.
Why wouldn't you tin? It makes soldering life SO much easier. If you are only twisting it together to make it easy to hold together, you may want to look at using a solder buddy or helping hands.

BetaFlight was born out of CleanFlight. They are similar, but different. In some cases (maybe all - I don't know), you can put BetaFlight on a CleanFlight board.
Here's a tutorial I found on how to do this (haven't done it obviously and there may be better tutorials - just the first one I found).
Obviously, wait until someone smarter than me chimes in to confirm or correct me.
I used to use cleanflight but I took the betaflight standalone off github to try.
& cleanflight took a while & for all I know still has not released a standalone.
You can swap the programming on it to BF pretty easy. I prefer BF now anyway.
Does CF have osd? Anyone. The fcb you got in that 2nd link ain't to hot. It's an old MPU6050 which we did warn you about but it's cheap. I know the score. But a decent knock will kill the gyro.
It's just an old naze32 that's been rechipped basically with the arm F3 but left the old gyro. Maybe alright for a bit of angle mode flying which I only recommend for a maiden or test.
You need to start on acro ASAP even LOS.
But definitely suspect for acro,
That vtx is ok. I get about 150-200 in a field on my IRC Duo. I do only have a little whip on it. I have a clover on a u.fl for the 130 but it's OK for now.
and finally off to a shaky start. Plumbing yesterday seemed easier.
After all the prep, I started soldering at the wrong end of the drone!
Hence the added notes so I can double check. I think I got lucky Worst case it could be soldering practice.
Quite why it feels like rocket science! (Electrickery )
@mozquito1 Just trying to find more arms.
I have an old computer fan I have designs on to clear the solder smoke. Thinking about mounting one back to front pointing into a flexible duct to act as an extractor fan.
