SA81FHMW smart servo, not only has a brand-new exterior design, but also a completely different internal structure from before. It have fully upgraded to the 4-Pole brushless motor high voltage circuit board, which can ensure output the 74kg-cm maximum torque and bear higher current with 38mm height. At the same time, adopt bigger size metal ball bearings and the matching steel gears of servo also be upgraded to a more suitable size, to make the servo work more smoothly and reliably. Programmable smart feature which allow the servo to be used in two modes: Regular Servo & Winch servo. Since it is a magnetic sensor waterproof IP67 servo, no environment will be an obstacle to your fun.
