Compatibility

Uses the PF-style 2×2 stud connector on the box. There is no socket hole: the gray 2×2 plug on a PF-style motor, light or extension wire presses onto the stud contacts. Check the connector in the photos against your parts before ordering.

What You Need to Make It Run

  • Motors and lights will not run on their own. They need a power source: a battery box, a rechargeable lithium box, or a receiver connected to power. Each is sold separately.
  • AA and AAA battery boxes do not include batteries.
  • How it connects: the gray 2×2 plug presses onto the 2×2 stud contacts on the battery box or receiver. There is no socket hole to plug into.
  • A basic battery box gives on and off (some also switch direction). For remote speed control you need a remote and receiver.
  • Not every part uses the same plug. Check the plug shown in the photo for the option you pick, and message us before ordering if you are not sure.

Product photos may include display scenery or other items that are not included. Check the selected option and What's Included before ordering.
