    Bottom line? This is the strongest most bad ass servo we know how to make. Period.


    What goes into this servo includes 6061-T6 aircraft aluminum, 35NiCrMo16 steel gears, SAE 660 bronze bushings, ABEC-9 bearings, BUNA-N o-rings, DIN-912 18-8 stainless socket cap screws, brushless motor, million-cycle potentiometer, gold-plated connectors, surface-mount components, plus a conformal coating. But what you can't see or measure is an intangible because you also get our best effort and dedication - our very heart and soul.


    If you fly IMAC maneuvers, centering is your single-most important consideration. After all, you can't possibly fly precise maneuvers otherwise. For you, one of the principal reasons for wanting this servo are the MIL-SPEC components and genuine Nobel potentiometer. These are game changers for the sport and while we pioneered their application expressly to suit our largest customer (the one delivering ordnance on a target 8000 miles away via GPS-steering), the intense R&D required just happens to suit your needs as well. Think of it as a little lagniappe derived from your tax dollars at work!

    We also pay very close attention to things like making them nearly impervious to dust, water, and exhaust-oil. How? Through the use of o-rings for sealing (a total of 13 of them) plus - where the wires exit the case - a custom seal and a special 3M-adhesive. By the way, notice how the wires aren't perfectly square where they exit the case. This is because the leads are soldered to the PCB by hand (to include both left and right-handed technicians) and before the glue dries, the wires relax to their natural set and rotate a little bit before the glue sets up. As it turns out, this results in a better seal than forcing them to stay 'square' to the case so it's an instance where ignoring our inborn OCD is a good thing!




    Better components. Better servos. The formula is simple. Decisions regarding what go into ProModeler servos aren't made in accounting (where they always optimize price and profit) but by engineering where they don't give a damn what things cost because it has to suit the mission. Of course we know this servo is a little pricey, but it's because we gave engineering a free hand. Sure, hobby-grade servos may offer similar torque and speed specs . . . but the difference is in how ours are built. It's a gut level difference!

    For example, marketing wondered why we didn't use titanium gears. It's sexy, they said. It's easier to sell, they said. Well, the reason has everything to do with steel having better mechanical properties for gears! Sure titanium, like carbon fiber, is sexy and easy to sell but if titanium were the be-all, end-all for gears, then in Formula 1 racing where it's very much a 'cost be damned world', they'd be using titanium gears, right? They don't for the same reason we don't, our engineers are of the opinion our steel alloy (nitrided 35NiCrMo16) is better . . . so engineering told marketing to stick it in their ear!



    Then there was the time accounting wondered why we use pricey Swiss-machined bronze inserts (we press them into the case for reinforcement). The way it works, under the kind of loads this servo may encounter, the aluminum pockets where the steel shafts fit are pounded so hard sometimes they go egg-shape (because steel is harder than aluminum). Since these are the shafts upon which the gears themselves rotate, once that happens gear wear accelerates because the gear-mesh has gone to hell (meaning a new set of gears won't solve the problem because the case itself is deformed).

    So engineering addressed the problem by reinforcing the aluminum bores with SAE 660 bronze bushings, which nobody in the hobby-business does to their aluminum servos. Granted, accounting had a point - the bushings 'are' a little expensive (and we use 3 in each servo) but it's only because they're very small parts (and thus, more difficult to handle which makes them more costly).

    Ultimately, their complaint boiled down to, "Our competitors fit shafts directly into the aluminum bores!" to which we politely observed, that's because we don't build hobby-grade servos! So basically, we told them to go pound sand - but very politely because they do the paychecks!



    So how strong is this servo? Well, 630 oz-in ÷ 16 oz/pound results in nearly 40 pounds, which is significantly more than a concrete block - or about as much as a 5 y/o weighs!



    Final note: operating voltage range is 4.8-8.4V, but optimal performance is obtained with a 2S LiPo instead of a BEC. In part this is because we don't know of any BEC that can reliably supply the clean current our high performance servos need at the same time as the drive motor is making it's maximum demands on the propulsion battery. Moreover, even if we knew of a BEC (either incorporated into the ESC, or a stand-alone unit) whose output wasn't garbage compared to even the cheapest LiPo on the planet, our advice is still . . . you're way ahead of the game by isolating control-electronics from noisy propulsion-loads. Yes, we know this means charging two separate battery packs, and yes, we know this is more trouble, but a dedicated battery for the radio is better. More here: https://www.promodeler.com/ask...

    Great servo for my X-MAXX

    Rating:
    Pros:
    Cons:

    Bought this bad boy for the X-MAXX and figured if the RC airplane enthusiasts trust it in their planes, I could trust it in a land based vehicle with no worries. At 6 volts the servo is an animal and couldn't imagine what it is like at 8.4 volts!


    ProModeler servos are the only servos I have left that are still working out of all the brands I own. I spent some serious money on other supposed high end servos only to have my ProModeler servos put them to shame.


    I like the fact that ProModeler is a small outfit business and their servos can only be found on their site. That is where other servo manufacturers make their mistake. Other manufacturers try to push quantity over quality because they supply to secondary vendors to sell their servos and the quality suffers.


    I would buy ProModeler servos even if there was a four week wait time, because the wait would be worth it! ProModeler servos are the only servos that I feel I am getting my moneys worth. If one ever did fail, (That is a very big IF) I would be O.K. with that because I know by the time if it ever did fail, that it had already outlasted ten times over any other brand servo I could have possibly bought on the market today.


    ProModeler servos are beyond their time (almost like they are a radically advanced type of mechanism utilizing quantum mechanics) and I hope that never changes.


    ProModeler, Thank You for making such a beautiful servo with laser etching! Also, Thank You for realizing that quality should always trump quantity. Other manufacturers have something to learn from the precedent ProModeler has set, but they are to busy being greedy to worry about quality.


    Don't ever change ProModeler, and I can guarantee I will never stop buying these servos. Heck, I would buy them even if it was just to look at them!


    Yes, they are that nice along with John's excellent advice and vast knowledge.

    • Surprisingly quick
    Cons:

    I'm very pleased with my DS630BLHV because it has loads of torque for my Axial RR10 2.2 Bomber and is surprisingly quick as well. The servo looks feels and performs like a tank.


    Very quiet and doesn't squeal

    The servo is top notch and way more heavy duty then my Savox 2290SG in my Slash. What I like the most is very quiet and doesn't squeal. I'm running this servo in my X-MAXX and recommend it.

    Zero high pitched squealing!

    Pros:
    • Center great and super quiet!
    Cons:
    • Wish I'd purchased these first.

    The most important thing to me is centering and with these servos it's rock solid. Also, before replacing the servos in my 105" SkyWing Edge 540 (NorthwestRC) I would go to do a pop top and it was slow. Now, after replacing the servos with ProModeler brushless servos (DS630BLHV on rudder and DS470BLHV everywhere else), when I do a pop top the model snaps around very fast!


    Also, like a lot of guys with these 120cc models, I run two servos on aileron and these ProModeler servos are easy to balance (so they're not fighting each other). I'm just using the balancing capabilities of the radio instead of an amp-meter or balancing box and these servos are really quiet. They have absolutely no buzzing. This is a relief compared to other brand servos that squeal and whine and drive me crazy. Don't you hate that? Anyway, better radios do the balancing for you and I'm glad these servos are very quiet.


    After flying them a while, I'm still glad I bought them. This is why I recommend you also get these for your model.


    Not my first DS630, not my last!

    I have been nothing, but impressed with my ProModeler servos. Besides the speed and power the construction is top notch. Coupled with an external BEC the DS630BLHV throws my TRX4 Sport’s heavily brassed out front end around like its weightless. This isn’t my first ProModeler servo and it definitely won’t be the last!

    Pros:
    • American made
    • Quality craftmanship
    • Superb specs
    • Fantastic response time
    • pure power
    Cons:
    • Too much awsome.
    This servo can toss around my weighted TRX-4 like a rag doll, it is glorious!!! I could not be happier with this purchase. It made a huge difference in performance and I can literally crawl up rock just using my steering. I now have 2 of these servos with plans to order more. The fit and finish of the servo is superb. American made craftsmanship at its finest! ProModeler is my go-to servo from now on.

    This is a really nice servo. It looks amazing, it performs amazing and if you spend $140 on a savox instead of a Promodeler, you should have your head examined.

    OMG this is by far the best servo I've had to run it in my X-Maxx 8s. Instead of haven't to do wide turns I can wipe it around in a instant. Going to get one for my other RC's as well. Well good luck and happy bashing

    I put a dozen ProModeler servos within my 43% PAU Edge 540 and I am very happy. The flight controls feature three DS470BLHV on each aileron, two more on rudder, plus a DS630BLHV on each elevator half. The engine gets a DS345BLHV on throttle and a DS360DLHV on choke - all into an Advanced Radio powerbox. I can't begin to express how precise they are and how quiet. There’s just no noise. Their performance in precision IMAC flying is absolutely great. They are simply the best servos I have ever used. I love em and I think you will too. I'm sold . . . nice Job John.

    The servo is everything I was hoping for! And after spending 15-20 min. on the phone (before purchase) with John, I have to say customer service is over the top. The servo works like a champ, its tough, rugged and if you like sexy parts, this is the one for you!

    Excellent servo!

    Cons:
    This is my second promodler servo, as usual the quality is top notch and nothing I have seen compares to a promodler servo. I don't think a stronger servo exists at this price point, I'm not just talking about overall tq output either the design is very robust. I beat my 470oz promodler for over a year in a 10lb rock crawler almost daily, and it still works great but I did notice some slop in it so I replaced it with the 630oz. The 630 is extremely strong and very quick and I have no doubt that it will last even longer.
