Description

A pull-back drive, not a powered one

Set 42199 uses a mechanical pull-back motor rather than electric motors or Bluetooth control, a system LEGO® Technic has used across several Monster Jam models. Pulling the truck backwards winds an internal gear train, and releasing it sends the model rolling forward under its own stored energy. There are no batteries, cables or apps to manage, and the mechanism resets simply by pulling the truck back again. It is straightforward enough for a first Technic build while still showing off real gears and axles rather than a plain click-together shell.

A compact build: 218 pieces, 61 part types

At 218 pieces across 61 distinct part types, the DIGatron sits among the smaller Technic sets, though the build still works through axles, pins and connectors in several stages. The modest piece count keeps the build approachable for younger Technic builders without stripping out the mechanical interest. Working through the parts list on this page shows exactly which specialist pieces drive the pull-back mechanism and the running gear, and how many of them could be reused in other Technic builds.

Black, red and blue, with orange accents

The colour scheme leans hard into the monster-truck look: black and red form the main body, blue adds contrast panels, and bright light orange carries the accent details that make the DIGatron stand out at a glance. That combination mirrors the bold, high-contrast liveries real Monster Jam trucks are known for on the circuit. The parts list on this page breaks down exactly which elements come in which colour.

Who this set suits

With no minifigures included, the set is built entirely around the vehicle: the build itself, testing the pull-back drive, and playing with the finished truck afterwards. That makes 42199 a good fit for Technic builders who care about mechanics over scenery, and for anyone who follows Monster Jam trucks from television or live events. The parts list also makes it easy to track down individual elements for repairs or for other vehicle builds.
