The RJX FS-0521THV provides the ultimate in performance for standard size servos. Cranking out a whopping 10.6kg and 0.03sec 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-0521THV 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.

Excellent servo for the tail of any large (550 ) heli. Lightening fast plus smooth and quiet in operationrnler gerekten ok kaliteli servoI have it install on the tail of my Assault 700.I have a mini vbar on it with a good setting. After first maiden flight of 5 min. flying return to land and suddenly the tailservo just stop working. I'm glad it happens about 1 meter above the ground otherwise I could have more damage. I have expect more quality of this servo for it price but for me I'll beter buy Savox or MKS next time. Bad quality!!!Best servo for sale in hobbiking. Ideal for the tail of the helicopter. I'll buy them for all of their projects. My friends are the same servos on their helicopters. All very happy.
