MG90D Full-Metal-Gear Digital Micro Servo, 180 Degree

The MG90 line covers a lot of ground between its variants, and the D-suffix version distinguishes itself with full metal gearing throughout rather than the mixed metal/plastic gear trains some MG90-family servos ship with - a meaningful durability difference for a micro servo working under repeated load cycles. Same compact 180-degree footprint as the rest of the MG90 family, just built for longer gear life under sustained use.
