I just buy a Fly last week, and been having problems since day one. The problem is that the machine keeps changing the speed of the rotation, this is not constant but it hapens often. It can't be from the power supplie because the same problem does not hapen with other machines. Also i tried 2 diferent power supplies and the problem continues(both power supplies are a Tsunami Lauro Paulini) Also the machine have been tested by 2 diferent tattoo artists.
HEEEEELP
