Loose Servo Screw

With time, the small screw holding the servo output arm can become loose or even come out, which causes the servo arm to slip off. If this ever happens during flight, you can easily lose your model to a serious crash. A very simple way to keep those screws in place is to add a very small smear of silicone adhesive/sealant. Just a little dab will do it, as you don’t want to use so...
