CleanFlight stick deadband
Have you experienced slow side drift on your quadcopter? Or maybe a yaw drift? To achieve a stable hover of your quadcopter first your RC Roll, Pitch and Yaw channels must be at the default midpoint of 1500μs. To achieve this, calibrate your transmitter sticks (if you have never done this) and then use the transmitter trims.
Next step: do your channels values fluctuate slightly? Ok, that is normal. No transmitter is perfect and sends perfect Midpoint-Signals when the sticks are centered. That’s why the “deadband” feature is so useful. The flight controller ignores the deadband value (in μs) and don’t consider it as valid. For example: my midpoint Pitch value jumps up to 1502. If I set a deadband value “2”, then the controller will ignore the slight fluctuation and think midpoint is still 1500 and not 1502.
Go to the CLI-Tab and type following commands:
set deadband = 2
set yaw_deadband = 2
The “deadband” parameter is for both Roll and Pitch axes. The “yaw_deadband” parameter just for the Yaw axe. That’s it. Now your quadcopter should be perfectly stable in the air. If you have any questions, leave me a comment.
