Rpeatable results in gazebo

I am trying to get repeatable results in gazebo, along with a ros_control in hector_quadrotor.

It seems as though the controller is giving me different results every time. If I disable the controller, the model falls freely - and the positions after every 10 steps can be reproduced consistently. But when I switch on the controller and set a constant velocity of z as 100 (the controller uses /cmd_vel) - I get different positions every 10 steps.

I dont understand why this would happen
