no these use IR... they only allow 3 tanks to operate at a time, why only 3?! I dont know LOL... they are virtualy identical to the Digi Q plastic shapes in some of the photos as if they were reverse enginered from an actual digi q.. but there are flaws and minor details missing, but other photos they are very different... and the treads were changed.. they have 4 lower wheels instead of the 3 that the digi q has, and its a not-so tall tread... well they might use radio for control....
