Sapro MS-10 Helicopter Units



Classic helicopter units from Sapro!  These are the MS-10 units that feature 10 X 12 volt 4405 par 36 - 30 watt bulbs.  The bulbs are all wired in series to create the 120 volts needed for operation.  Unfortunately with the wiring if 1 bulb goes out they all go out.  I am planning on adding neon indicator fault lamps in the future to make trouble shooting the lamps easier.  The units rotate at 30 RPM by a common Dayton motor.  This creates an awesome spectacle of spinning light.  Gels can be added for coloration.  Great units made in France!
