"This rugged 4 x 4 is powerful with great suspension and brilliant colour scheme. The new Control+ unit and 3 motors significantly affects the price, but well worth it for the smooth control and play value. The Control+ system is sensitive and gives great control over speed and steering, .letting you make it crawl or race. Control+ has a specific memory requirement which will not operate on older mobiles. ( I must confess that I had to upgrade my old mobile for this, but it was well worth it.) Looking forward to more Control+ models in the future, especially the Liebherr excavator coming October 1st."
