No. It is mechanically operated. The "sled" operator puts the transmission into neutral, yet puts the box drive into forward gear. As one set of axles moves down the track, the box moves up the rails. When it hits a certain point, the pan on the bottom drops, digging deeper into the dirt. At the end, the rear of the sled raises for gravity to ultimately stop the competition vehicle
