Answers.Text: The motor is indeed mounted upside down, which could result in the grey parts sticking out far enough that the wheels do not touch the ground anymore.

Comments.Text: So the motor-powered wheels roll freely when you hold the model up? And when you put it down on the floor it won't move? The insect-like legs are designed to be moved by the forward motion of the model. Check that these two leg sections are not blocked.
