Rate Tuning (Part 1) | FPV 101: Phase 5, Episode 8a

By | November 18, 2022

Changing your rates affects the drone’s reaction to transmitter inputs, making your drone more or less responsive to stick movement.It’s a lot like setting your controller sensitivity in a video game, and like a video game, these settings are entirely dependent on your personal preferences and style.

[Music] Foreign [Music] We're going to be talking about the Basics of rate tuning in betaflight Changing your rates affects the drone's Reaction to transmitter inputs making Your drone more or less responsive to Stick input it's a lot like setting your Controller sensitivity in a video game And like a video game it's entirely Dependent on your personal style and Preference the basic rule of thumb is That the higher your rates are the more Your stick inputs will result in Faster Twitchier flight characteristics with High rates even small stick inputs will Yield a very high response from the Drone this can be an important thing to Consider when deciding whether you want To use your drone for freestyle or for Racing generally Racers will often tune Their drones to lower rates while Freestyle Pilots usually tune their Rates higher lower rates can help a Racing pilot achieve better Precision by Making it easier to hit specific lines With little over correction a freestyle Pilot on the other hand doesn't have to Run Precision lines and might tune to High rates to allow for quicker Acrobatic Maneuvers as well as faster Reaction time to flight conditions and Unseen obstacles however this is

Entirely up to personal preference and Is all about how you as a pilot want Your flying experience to feel before Changing your rates you should first fly Your drone to get a feel for your Default tune from there you can take Note of any flight characteristics you'd Like to change any adjustment to your Rates will change the relationship Between your drone and transmitter so It's important to make changes in small Increments to see how they affect the Way you fly So now let's jump into betaflight and Take a look at this process before Connecting your drone to the software Always remember to remove your Propellers not doing so can result in You severely damaging your drone your Workspace or most importantly yourself Especially if you're planning on Plugging in a battery Once connected head over to the PID Tuning tab From there navigate to rate profile Settings Here you will see three parameters RC Rate super rate and RC Expo these are Used to tune the flight controller's Reaction to inputs on The three Principal flight axes roll pitch and yaw The flight axes are color coded with the Same colors reflected in the curves of The rates preview below

The curves themselves represent the Sensitivity at different stick Deflections for a lateral control like Yaw far left side of the curve Represents sensitivity at full stick Deflection to the left and the far right Represents full stick deflection to the Right for a vertical control like pitch The left represents a downward stick Movement and the right curve an upward Stick movement The steepness of this curve at either End represents increasing sensitivity of The Drone to transmitter inputs past 50 Percent stick deflection the very center On the other hand represents sensitivity At zero deflection The nature of this curve being flatter In the middle and more curved at the Ends allows a pilot to make more subtle And smoother movements with smaller Stick inputs and faster twitchier Movements with large stick inputs the Velocity of your full stick deflections Is also measured by the rates preview in Degrees per second this number describes How quickly the whole drone can rotate On that specific axis let's say you've Tuned a drone to have a roll of 360 Degrees per second that means it'll take A drone one second to complete a roll at Full stick deflection Foreign
