Lego Technic adds a pair of two-in-one monster trucks to its catalog

After spending time in the pits, Lego Technic is visiting the wild world of monster trucks by releasing a pair of kits created for kids age seven and up. Its Grave Digger and Maximum Destruction replicas are relatively easy to assemble, they feature a pull-back mechanism that propels them forward, and they can be rebuilt into buggies.
