    Looking or the Holy Grail of PID's

    So, another test flight, with some less wind above my favorite rice field. If anything goes wrong, a wet but soft landing and a sure but muddy recovery ;)

    Changed back to CF Vision Style Props, they are very jerky in high winds, but do ok in moderate and no wind. One T Motor (just a few flights :( ) has developed a bad sounding bearing.

    Although the SimpleBGC manual states you need to increase D to decrease low frequency oscillations, which I think I have in my previous videos, I tried decreasing them.

    This sort of helps. Stability is improving, but still vibes and a bit of slow oscillation, aka wobble.

    Did an advanced calibration again, horizon still drifting but a bit better.

    Current SimpleBGC settings:

    PID:

    ROLL: 30,0.35,16
    PITCH 12,0.35,14
    YAW 14,0.3,14

    Motor Config:

    ROLL: 106
    PITCH 66
    YAW 84

    GYRO THRUST 94

    Follow Yaw Deadband 6 degrees.

    Balls used: 6 soft black ones, and two blue balls from my Goodluckbuy gimbal, since I tore a black soft one up, they are like chewing gum don't you think?

    I janked the Phantom around a bit, this was not a lets go slow flight.

    Next will be decreasing D even more I guess, add a little P?

    For the people who like to see contextual videos on youtube, right click open in new window:

    For the people knowing a lot about forums, but less about smooth video:

    Shot with Gopro at 60fps, video cut and saved at 30fps.

    Ow, if its not in the settings, you have to buy a better quad.

    But it wobbles, mostly in pitch. Must go.

    Looking really good, especially the bits where you can clearly see the Phantom turning hard and the horizon stays level. :D
