When cutting out the sections of covering for the fitment of your servos, instead of cutting a rectangle shape to match the servo, cut a simple X instead and then slide the servo into the servo bay. As you push the servo into the fuselage or wing, the fabric goes with it and gets pushed neatly inside with the back of the servo, leaving no nasty fabric edges where you have cut the rectangle area out. I use this on all my ARFs and the end result is a very neat strong finish with no chance of the fabric coming loose over time. Heating the edges with a covering iron will give a nice clean corner and make sure the film is well sealed at the cutout.
