Sullivan Sky Writer Smoke Pump System, 6V

Skywriter Onboard Smoke System
Making use of an internal microprocessor, the Skywriter has a digitally managed smoke rate (with a programmable radio). This allows you to adjust smoke rate during flight and/or slave it to your throttle servo. It features an ultrasonically welded direct drive pump head, and weighs less than 4 ounces. The pump can run from any 4.8V to 12V battery (6V + advised). The set includes tubing, fittings, a double screen filter and check valve, whatever needed except smoke tank and smoke muffler!
