AGFRC 55Kg High Torque 0.087Sec Speed Brushless Standard Digital Servo For RC Car Boat Airplane (2026 Special A81BMWP)
This new standard case 55kg servo A81BMWP is a PRO version A81BHMW, keeping the same size but with superb powerful motor, suitable for professional competition drivers who pursue the ultimate and extreme, or for the project engineer with limit budget but with high quality requirements.
Full aluminum case and structure, hardened steel gears, and an advanced motor, excellent linearity and precision control. All these are optimized to allow the servo to produce 55 kg 0.087 sec spec at 8.4V regular voltage. The servo is particularly suitable for large rc cars and giant aircraft and other demanding applications with an emphasis on high thrust and accuracy. Super fast response of the control electronics and high long-term durability.
Withstands immersion in water to a depth of 1 m for a 30-minute test run, it is suitable for off-road models of cars, ships, and submarines - simply for places exposed to the effects of dust and moisture, with high demands on the tensile strength and overall mechanical resistance of the servo.
