These are motor mounts for the jumper 260 plus quadcopter. The stock motor mounts are made from 1.4mm single sided PCB. They are cut near mounting holes to look “pretty”. My redesign removed the cut out and adds copper pours on both sides to increase strength slightly. LED’s are retained, You will have to remove LED’s from old motor mount. There is a 330 Ohm current limiting resistor in series with the supply to motor mount. The supply is 9 Volts.
