    Rumor around the camp fire is that Dick(Richard) & Bill caught wind that the AI filter had a sensor value named Preston. And as it turned out it was just dynamic notch on gyro/dterm. To this day Dick(Richard) & Bill are still holding him accountable for his treachery.

    It took me 3 years to understand those filters and create a strategy how to teach them to our sales at work (high speed checkweighers) - with great success!
    Your vid however tops all of my work by far and would have made my life so much easier! ;D

    The visualization of time domain filter delay and how frequency domain calcs translate to a sliding average is a novel way of presenting! This is worthy a Matlab control tech talk or equivalent. 👌

    Thank you for all you do for the community Limon! Visualizing latency will hopefully get more people into tuning, it is seriously fun and beneficial.

    Awesome. If you are not lazy - do some tutorial, how to manage all filter setup BF 4.4 with real scenario - by gyro data (noisy/medium/clean). Please. You have ability to explain. (thumbs up). BTW - if you add some additional situation - with cracked frame, or so - You will be the first person, who do this.
