<strong>Orbita Revolution Six Rotorwind</strong><br/><br/> Meet the Revolution. A contemporary spin on our popular InSafe series, with a space-age" appearance. The case is formed from durable aluminum sheets and then Heliarc welded. All weld seams are ground by hand to provide a totally seamless construction and then the whole case is powder coated. The resulting finish is both attractive and durable. The Revolution is powered by four long-lived lithium D cell batteries. In addition to a master switch, each winding head is individually powered with its own on/off switch and operating mode switch"
