No worries Wheelz. Some of us have done this 20-30 times.
If you can post video of what is happening (good high def, well lit, stable, not vertical video) it may help.
Most flight controllers have an arrow pointing to the front of the copter. Is your flight controller oriented correctly on the copter? If you turned the flight controller so you could get to the USB port, you have to tell the software or your copter will spin.
When you have the copter connected to a computer and are looking at the software (betaflight, cleanflight, kiss whatever), you should be able to run each motor by itself (with the props off). When you start motor 1, does motor 1 start? When you start motor 2 does motor 2 start etc..? This is critical. The flight controller works because when it calls up motor 1 it knows where motor 1 sits in relation to the flight controller. If you connect motor 1 to the motor 2 pad on the flight controller (or any other variant), the copter won't fly.
Do all motors start at EXACTLY the same throttle input? If any of your motors 'jitter' stop and re-do the solder joints between the motor and the ESC. These connections need to be perfectly soldered.
While your copter is connected to the computer you should be able to see your sticks move in the transmitter tab. Do you have a reversed channel on your radio? If you are pushing right yaw and the copter is getting left yaw, the copter will spin on the ground.
Do you have all your motors spinning the proper directions? You should have two motors spinning CW and two CCW. The writing on the props ALWAYS faces up. If you have a motor spinning the wrong direction or a prop upside down you will spin or flip. An upside down prop tends to howl.
Start here. Post video if you can and lets get this in the air!
