    What's this servo for?

    Suitable uses for a DS125CLHV include small unmanned vehicles for civilian consumer, defense contractors, and industry alike. Examples include;

    • 1/24th scale RC crawlers
    • Fixed-wing 3D aircraft
    • Tactical surveillance UAVs
    • Micro rotary-wing applications

    MIL-STD-810G-Part 16

    • Shock - Test Method 516.6
    • Vibration - Test Method 514.6
    • Rain - Test Method 514.5

    Making the ProModeler DS125CLHV better than hobby-grade servos, is it's built with MIL-SPEC components and tested to these MIL-STDS (military standards).

    These are real world ownership considerations applicable to civilian-use, also.

    Product Details

    Popular with defense contractors and industry, civilian users of the DS125CLHV also include modelers for whom the bottom exit servo lead makes it ideal, like the immensely popular Axial SCX24 micro crawler. Others who benefit fomr the strong steel gear and rigid case structure include aircraft modelers who require an extreme duty sub-micro servo like those from Extreme Flight because while tiny, it's fast  and precise centering results in a feel unlike anything else on Earth. Especially when durability is the significant consideration.

    Demanding model applications require our best performance considerations - like centering, power, and speed - but always rugged durability above all. This servo is engineered to deliver in spades! Let's see where the ruggedness is built in.

    For example, the all-alloy case looks trick, but lots of imports servos have alloy cases. What separates ProModeler is how it's built.

    Case has several jobs . . .

    • Mounting tabs
    • Cooling fins
    • Transmission section
    • Hard points for gear shafts
    • Steel gears
    • Environmental protection (seals)

    Electronics Section

    • Million-cycle potentiometer
    • Potting compound on PCB
    • Slip-fit brushless motor

    To begin, the foundation is the 10-bolt construction. It's one where Allen head machine thread fasteners thread into the center case. This makes it more rigid in torsion (twisting force that's trying to lever the case sections apart and screw up the gear mesh). Reason this is important is if the gear-mesh changes under load it creates bad wear patterns leading to failure (basically bad juju for any servo).

    Speaking of gears, they're all-steel. Why steel? Simple, because it's the best and most durable material available. For example, did you know NASCAR, drag racers, Ferraris, and Corvettes use all-steel gears, also? There's nothing better. Fact.

    But equally important is where the steel gear shafts are anchored. In this servo, the gear shafts are anchored withing bronze hard points embedded into aluminum. These reinforce the case and spread impact loads. Servos without these soon end up with round bores for the shafts that get pounded into an egg shape, thus allowing the gear mesh goes to Hell.

    Believe me, if that happens then it's new gears 'and' a new case because you can't put new gears into a case with worn bores (you can but they'll get trashed really quickly). So what this really means is those servos are throw aways. It's out view you're better off if we reinforce the case to begin with, agreed?
