DYS 25kg Waterproof Digital Servo, 8.4V, IP66, Full Metal Gears

Not every outdoor or wet-condition build needs the maximum torque a 45kg servo provides - a mid-weight control surface or actuator often does better with a lighter, more efficient 25kg unit, as long as the water resistance is still genuinely there. DYS's IP66-rated version covers that middle ground, full metal gears for durability under repeated load alongside the 8.4V power handling that gives it real holding force without stepping up to the bulk of their heavier-duty waterproof servos.
