Description
Forgot to remove roofmount.
Please note, this is just a prop siren (NOT a propeller siren). This didn’t work since no sound-emitting block is available as a mod in KSP. You may put an Infernal Robotics part or put a compact rotator under the tiny structural panel to make the siren rotate.
