I cobbled this moving target together using a JJRC truck (still stock electronics) and one of Tank Hobby's IR target circuits. The truck will run with or without the IR target circuit turned on. One shot from a tank stops the truck instantly by shutting off the power from the battery and also lights up the 4 red LEDs in the custom kitbashed "Apple" that I designed and 3d printed using parts from an old Heng Long IR apple. The red LEDs stay on for about 20 seconds and a speaker makes an explosion sound, then the truck turns back on, ready for more.

The target circuit is a stand alone unit that will fit into, and work in any of my JJRC or WPL trucks. I designed a tray the speaker and circuit and battery all sit in that holds a boom that holds the apple. It just sits in the truck bed, has it's own power (9v) and cuts the power feed from the truck battery (6v) to the truck when it receives a IR hit.

It's a soft skin target the tanks can shoot at.
