Betaflight tuning guides
Practical, no-nonsense guides to tuning your quad and reading what the log tells you.
The optimal tuning flight
How to fly so your blackbox log yields the best possible analysis — a few targeted stick inputs per axis.
How to read a Betaflight blackbox log
A blackbox log is your quad's flight recorder. Understanding the key traces lets you judge a tune objectively — instead of going purely by feel.
Set up blackbox logging for the best analysis
An analysis is only as good as the log. With the right blackbox settings, PIDoctor gets the data it needs for the full filter and PID diagnosis.
Diagnosing motor & D-term noise — filters, not PIDs
Hot motors and a twitchy quad often look like a PID problem — but they're frequently a filter problem. Here's how to tell the difference.
How to fix propwash in Betaflight
Propwash — the shaking in fast descents and hard turns — is one of the most common tuning frustrations. It's usually not a single value but the interplay of filter delay and damping.
PID tuning basics with step response
The step response is the most honest view of a tune: it shows how the quad actually reacts to a control input. Read it well and you tune deliberately instead of guessing.
Filter tuning: gyro/dterm lowpass, dynamic notch, RPM filter
Filters decide motor heat and latency. The goal: filter just enough to keep noise off the motors — and not one bit more, because every filter costs delay.
