EMAX ES3005 Waterproof Metal Gear Analog Servo

The EMAX ES3005 is a 42 g standard-size analog servo with metal gears, dual bearings and a waterproof case. It suits RC planes, gliders, boats and cars that run through wet grass, spray and rain, and at about 12 kg·cm on 6 V it handles large control surfaces, steering and rudders.
