The RJX FS-0521HV provides the ultimate in performance for standard size servos. Cranking out a whopping 21.3kg and 0.05sec transit speed @ 8.4V, you will be hard pressed to find a better servo for your money. The massive torque and lightning fast speed makes this servo ideal for use in large 3D helicopters as a cyclic or tail servo, giant scale airplanes and even large cars/trucks. The entire gear train is metal, making stripped gears virtually impossible. The case is machined from aluminum alloy providing the ultimate in durability and offering excellent heat dissipation.
The FS-0521HV is a true high-voltage servo capable of operating at a constant 8.4V, yet still yields impressive numbers at as low as a 6V input. This makes it a very versatile servo which can be used in many different applications.
A full set of servo hardware is included, as well as an alloy servo arm ideal for use with helicopter cyclic servo applications.
