Not real sure what you are asking, I think you mean the stitches on this machine when straight sewing not FMQ. I have the 1500s and love it, stitches are good and consistent at any speed I have used so far. I do not have a stitch regulator. It can sew extremely fast, I have to make sure not to press pedal so hard, not do to stitches but due to me not being able to hold fabric straight at high speed. Right now mine is on a frame and my sweetie had to devise a governor for me to help keep consistent speed so I don't get going so fast when doing FMQ. One thing I found was the machine will still sew if you forget to put the pressure foot down and the back is all tangles then. My other machine would not go if the foot was not down, so I have had to remind myself to check the pressure foot lever. So far I feel it's a great machine for the price. Also mine came with the FMQ foot and walking foot and some others. Also, there are several adjustment levels for the feed dogs which helps get consistent stitches for the type or thickness of what you are sewing.
