Waterproof 45kg Coreless Digital Servo, 8.4V, Full Metal Gears, IP67

Coreless motor construction gives a servo smoother, more responsive movement than a standard brushed design, and pairing that with a genuine 45kg torque rating and IP67 water resistance covers both ends of a demanding outdoor application - a large control surface that needs real holding force, used in conditions a standard servo's splash-resistance wouldn't survive. Full metal gears round out the durability case for sustained heavy-load use.
