hey,
the drive motors are reasonably powerful, it was strugling to move that monster truck around because its got 4 big gripy wheels and its on my bedroom carpet, if you see that other fw robot in the back ground of the video, i tried getting it in the claws aswell and i could pull it about everywhere, as for the grip when i grabbed the same robot and i could pick up my robot and carry it about and the other robot stays in the claws and goes with it. but yeah a decent grab rather than crush.
