    When flying, my drone exhibits an intermittent but frequent behavior, where it will, unbidden by my remote, tilt right and lose altitude. Up high it doesn't last long enough for it to crash, but when I try it 20ish feet up I have to throttle up to keep from hitting the ground.

    Drone video of this behavior:



    Does it twice, I'm not touching the sticks other than to pull it out of the dive and bring it back over to the left.

    Theory based on my minimal comprehension of how quadcopters work: It's losing power to one or both right-side motors, thus tilting (and moving) right; left motors slow down to try and level out, resulting in loss of altitude. Does this make sense?

    This began occurring after a crash caused me to have to replace the motor and ESC on the front right corner.

    Things I have tried:

    Compass calibration
    Confirmed the new ESC matches the other three
    Having my poor solder on the ESC/motor redone by someone else
    Checked via the Windows assistant program that my remote isn't sending bad inputs

    I hope someone has some ideas, as this feels pretty unsafe to fly like this.
