? I used a lot of tape to stop the "motors" from moving around. Maybe this makes you think it look like cotton balls? LOL. Anyway it is not fast as the 400D is such a big co-axial heli. And the servo arms are very short (only around 6-7mm from the screw to the ball). Makes it very slow but stable for beginner. I think for experience pilots may prefer to switch to longer servo arm for more cyclic input.
