You'll always have friction, it's get a matter of minimizing it. You know when you have a good skirt when you can slide it across a hardwood floor and it glides for a few feet before stopping.So far, I have been unable to create a device that hovers to my satisfaction after several attempts . How do you know when you've reached that point of zero friction? I've dedicated a significant amount of time to putting holes in the skirt, but it still seems like the static friction isn't negligible. Is the solution just more holes or is there something else I'm missing? I'm starting to stress about this event because I'm blowing through batteries really fast trying to get this thing to hover right.
