This is an air raid siren built to go inside a Stuka dive bomber model. The Stuka was a German terror weapon used in WWII. As it dived to drop a bomb, a siren would sound out from the plane to terrify the people they were bombing. This siren is powered by a small 25 amp brushless motor at 850kv on a 3s lipo battery and a 30amp ESC. It is very loud and effective so ramp it up slowly if you make one and worn the neighbours if you live in a place that has tornado's. Have Fun
I will post a test vid on here soon.
