Description

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.

Fast, precise, powerful, and indestructible. Specs are dead-on. I've modified 4 of these for continuous rotation to power a combat robot. They run extremely smoothly and ice-cold, even when stalled. They should handle over-voltaging well. No need for plastic servo arms since the gear train and bearings are rock solid (and easily replaceable).

High speed under load. High precision. At the same time - a phenomenally quiet servo. Will be used on 1/8 on_road

Excellent.

I'm using it in my 1/8 e-buggy(dex408). Very fast and powerful with 4.5A / 7.2V BEC from HK.
I've disassembled it and made it waterproof before winter championship (gearbox with extra grease Gummi-Isolierung(ger.) on elements foam-rubber piece between servo and servo horn). 4 events passed at temp from -15 to 3 C with show and water condidions.

It's perfect.

Pros: EVERYTHING
Cons: None, really
That's one fast servo. And strong. In fact, it is the best I've ever seen. At that price, get it. Get it. Worth it. Yup. mhm.

These are the best servos for the helicopter. I installed them on gasoline helicopter 700 class. They work perfectly.

These servos are so solid feeling! I bought four of them for a 30cc plane. one started acting up for whatever reason. Told Hobby King about it and they offered to send me a new one or refund me! They didn't even want the faulty one back! Amazing service!
