For Sharper Image DX-4 Drone Set of Motors

2 A and 2 B motors. If you need your toy to be fixed, you can use this set.
Since motors have different rpm because of different manufacturer, I advise you to replace all of 4 motors at once.
Otherwise, you can get problems while flying the drone.
You need to solder all 4 motors to the mother board and play with your toy for a long time again.
