I do most of my FMQ on a basic Mechanical Brother that doesn't drop the feed dogs. I set the stitch length on zero. I have covered up the feed dogs with the supreme slider but one time I forgot to use it and didn't notice any different. I find that if I get eyelashes it is because I am going around the curves with the wrong combination of machine speed and my hand speed. I have never adjusted the tension, top or bottom. I am not an expert, but can do a respectable job of meandering.
