This could occur as the time steps in the simulation are too large and it becomes unclear in what direction the propellers are spinning.

We should check for some ratio of the max_rot_velocity_ and the sampling_time_. In the gazebo_motor_model.

yes, and then issue an error or something "loud" actually, since we found that this screws the dynamics up entirely.
