The tightets the build, the cleaner the flight will be
Tighten all the screws
Fix the cable using hot glue for instance
- A good tip, it putting a hot glue drop then cleaning it with cardboard, that way you only have the right amount of glue and it goes in the small holes
- Also hold the parts for at least a minute in the desired position so the glue can solidify
Weight distribution is very import, your quad should have most of its mass in the center and equal distribution of weight for each axes

If you have trouble being precise, do not hesitate to add expo to stick input
It's increase travel of sticks in the middle needed for the same amount of movement and decrease it at the end for faster response
Never add expo on the transmitter, you'll loose some stick definition
Add RC expo on Betaflight, starting from 0. 30% (0.3) RC expo is a good starting point
Add Throttle expo if you have trouble holding altitude, it's a very good way to control height ant altitude

Race can be configured at your own preferences
Usually racer will prefere low rates (without rc expo) and freestyler will prefer high rates
~600 degree/second for racer and 1000+ degrees/second for freestyle

Starting from Betaflight 3.2 filters is a different topic because it supports dynamic filtering
Activate dynamic filters right away, it'll detect unwanted frequency in the gyro and filter it
On a clean build (tight and weight well distributed) you can switch low filter pass to PT1 and disable Gyro Notch filters 1 and 2
Always check for motor temperature when disabling filters

Activate antigravity mode to fix pitch wobbles on throttle cut
If you have vibrations or stange behavior at high throttle, note the value of the throttle and lower TPA near this value
