The Savox SW-1212SG Plus is a waterproof high voltage coreless digital servo from Savox's Blue Line — the range built for boats, trail crawlers and RC builds that encounter mud, water and extreme terrain. Producing up to 52kg-cm of stump-pulling torque at 8.4V and sealed to IP67 standards, this servo is made for monster trucks, high-torque crawlers, scalers and marine use — anywhere conditions get wet and the loads get serious.

Built with a coreless motor and specialized steel gears, the SW-1212SG Plus uses a hybrid aluminium/composite case for strength and heat dissipation, runs on twin ball bearings with a super high 12-bit PCB for precision, and carries a long 450mm lead for larger chassis. The common 25T output spline gives broad servo horn compatibility. One fitment note: at 46.15mm the case stands taller than a typical standard servo — worth a quick check against your servo bay.

As part of the updated Plus range, this servo includes Soft Start and Sanwa SSR compatibility. With a full 6.0–8.4V operating range, it runs directly from 2S LiPo and delivers its maximum 52kg of torque in HV installations, no external BEC required.
