Description

This new standard case 55kg servo A81BMWP is a PRO version A81BHMW, keeping the same size but with superb powerful motor, suitable for the professional competition drivers who pursue the ultimate and extreme, or for the project engineer with limit budget but with high quality request.
Full aluminium case and structure, hardened steel gears and the advanced motor, excellent linearity and precision control. All these optimized to allow the servo produce 55KG 0.087Sec spec at 8.4V regular voltage. The servo is particularly suitable for large RC boats, cars, 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’ cars, boats 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.
