Just built a new 220mm quad with Brother Hobby 2205/2300 motors. Motors are paired with Little Bee 30A BLHELI ESCs. During flight I have noticed a micro stutter. Generally while hovering or during a descend . It is not bad enough to cause the quad to go out of control. I hear it in the motor and see a very slight "yaw jitter" from my goggles. The quad flies great and is not generally affected by the stutter, but curious on what could be causing it.

Other info:
- ESCs have damped light on
- 4S
- 5045 bullnose props with 2 blades

Is it a horizontal descent? If so, my first thought would be that your PIDs could need some more work done. It is always hard to tune out propwash oscillations if that is what you see. What firmware are you using? Have you tried looking at a Blackbox log to see which axis causing it?
