This is an 60mm impeller air raid siren.
It is extremely loud. (120 dB from my smartphone app 'noise meter')
In this video, I throttled the motor just 30%. because I didn't want to be caught by the police.
So if you give the motor 100% throttle, it is louder than this video.
This siren is powered by a 2204 brushless motor (GARTT ML2204S 2300KV) on a 3S Li-Po battery and a 20amp ESC.
It has a 'Siren Base', so you can attach this siren you want.
It is assembled by 3mm screw.
