unable to control quadrotor via joystick

[hannesharms]

While spawning a quadrotor in gazebo following message occurs: Controller Spawner couldn't find the expected controller_manager ROS interface.

This error occurs because of a wrong xacro tag in quadrotor_controller.gazebo.xacro I was able to fix this by deleting the unnecessary line:
<xacro:macro name="quadrotor_controller"><

Hi, I'm not a developer of this package but:

you need to catkin make the packages... during the execution of cmake the *.in files are transformed to real xacro files... The line is not unnecessary
