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

Go to instructions for links to the motor parts.

I will post a test vid on here soon.

Instructions

I have made the motor mount in a way that you can import it into Google Sketchup and redesign it to suite what ever motor you are going to use. The outer circular part of the motor mount just glues into the main stator. You will see how it all fits together. This was a cool project and now all my neighbours hate me. Just added a modified impeller to suit a 6mm prop adapter. Also added .skp files for sketchup.
