Let's start of by configuring the basics.
Connect your drone to Betaflight and navigate to the "PID Tuning" tab.
In the "PID Tuning" tab (#1), you will see a tab bar with three items, open on the "Filter Settings" tab (#2).
Now apply the following
- Disable "Gyro Lowpass 1" (#3)
- If your "Gyro update frequency" is the same as your "PID loop frequency" (You can find these in the "Configuration" tab), disable "Gyro Lowpass 2" (#4) as well
- If your "Gyro update frequency" is NOT the same as your "PID loop frequency", move the "Gyro Filter Multiplier" Slider (#5) to the maximum of 2.0
If you are unsure about what to do, take a look at the attached picture which highlights where you can find all of the input fields / information.
