Build

• 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 mose of its mass in the center and equal distribution of weight for each axes

Betaflight

Expo

• 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

Rates

• 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

Filters

• 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

PIDs

• 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
