Big Action Construction Site introduces preschoolers to RC vehicles & features an interactive playset full of action-packed construction fun! The easy-to-use RC controller steers the truck in 4 directions - forward, back, left & right - with 4 color coded buttons related to colors on the truck It also has tank steering so the vehicle slows down as it turns, making it easier for kids to maneuver & control. Bring the RC Vehicle to the playset where EZ Guide Ramps automatically aligns the vehicle so even the youngest kids find success driving it to the play areas. First, there's a cool elevator - kids drive onto the pad & the vehicle magically rises to the 2nd level; drive around or back-up to drop off cargo in the hopper loading area. When they drive to the other side the elevator magically lowers the vehicle back down to ground level. An "easy button" allows manual elevator action as well. At the Crane, load/unload boulders with the plunger claw or drive to the Hopper where boulders are magically loaded from the upper level. Bottom level also features parking area and gas hose. Set comes with 2 boulders.
