    Smooth and powerful, the water resistant DS360DLHV is a high voltage (HV) digital servo built on a tough hybrid case, which is crafted of aluminum and engineering polymer plastic. Equipped with cooling fins for heavy duty use, the center-section is CNC-milled from a solid billet of 6061-T6 aircraft aluminum. Meanwhile, the electronics cover (bottom) and the transmission section (top) are injection molded of impact resistant fiber-filled Nylon 6,6 (like what's used for a Smith & Wesson handgun frame), and the upper is reinforced with bronze hardpoints where the steel gear shaft fit in their pockets for maximum durability. Secured together with 10 Allen-head bolts instead of Phillips head screws, and equipped with dual ball bearings plus all-metal gears (for durability), it outputs 360 oz-in of torque - or well over 20 pounds of force! With a transit time of just 0.14sec/60°, this is what's called a standard-size servo - meaning it fits most remote control models.

    INTRODUCTION:

    Part of what makes the ProModeler DS360DLHV better than competitors is that unlike hobby-grade servos, it's built to meet military standards (and subjected to these tests).

    MIL-STD-810G-Part 16

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

    In part, this is due to the requirements of our primary customer. However, because we're modelers and have knocked a servo off a workbench, experienced crashes, and know a thing or two about engine vibration. it's built with 13 o-rings because like you, we know how a summer afternoon pop-up rain shower may drench a model before landing, plus we like splashing through puddles with a buggy, or flying off water with a float plane. It's why these tests are important for civilian users, also!


    Ownership Considerations:

    Serious modelers - whether they're flying precise maneuvers, or working a course with a buggy or sport truck - often opt for ProModeler servos because of superior centering performance. In part this results from our using MIL-SPEC components, but it's also due to our using a genuine Japanese Nobel-brand potentiometer versus a cheapo clone, inductive pickup, or some other cost-saving measure.

    The DS360DLHV servo is perfect for models ranging in size from 1.20ci (20cc) through to 120cc giant model aircraft as well as 1/10th buggies. It's been expressly crafted to meet your needs whether you're a beginner looking for your first set of high quality servos, a highly experienced sportsmen attending several events or fun flies each summer, or an all out pro!



    DETAILS:

    If you're an electrical engineer you'll immediately notice we protect the PCB from vibration with a conformal coating instead of a little square of foam rubber. Referred to as potting compound on the civilian side, we call it monkey-snot because it's such a sticky mess to apply. This stuff is applied to the PCB and oozes between components and once it sets is what lets our servos thrive in harsh high-vibration environments. This is an aerospace-grade technique and it makes ProModeler servos more valuable.



    Another area where a ProModeler servos stand out is protection from environmental contaminants, typically dust, water, and exhaust-oil. The assembly of the DS360DLHV is protected with o-rings - basically at every opening - even beneath the screw heads! We all know how pernicious water can be with respect to penetrating where we don't want it so that this makes ProModeler servos better than servos without this level of protection is a no brainer.

    As you learn how well the DS360DLHV servo is made you might reasonably expect this to be our most expensive servo, but it's not. Instead, this is our best general purpose servo. It's the servo that expert modelers select for a wide variety of sport and scale models. For example, savvy pilots - ones who grok what Eastwood meant (in the role of Callahan in Magnum Force) when he said, "A man's got to know his limitations." - will opt to use these for models as large as a 120cc gasser. Especially when they're intended for sport use versus 3D. For example, for performing old-school aerobatic maneuvers like loops, point-rolls, stall turns, as well as occasional snap maneuvers and Lomcovák.



    Ever taken a servo apart? The metal gears rotate on steel shafts. The end of the shaft fits in a hole in the case, what's called a pocket. In cheapo servos, the steel fits into a plastic pocket but in a ProModeler servo, there's a brass insert reinforcing the plastic. When you pay a little bit more for a ProModeler servo, this is part of the reason why. As long as it moves, we know modelers won't throw anything away . . . so we produce ProModeler servos with the expectation of a service life measured in decades!



    USE CASES:

    So who uses these servos? In light of the MIL-SPEC and MIL-STANDARD test methods, you won't be surprised to learn the government has driven a lot of our product development. They're our biggest customer. So are universities, plus commercial UAS operators in agricultural and pipeline inspection ops. We've branched out to the civilian world, so our customers now include hobbyists.


    FAQ

    Q. I have a 104" Extra with a DA120, is this enough servo? All my buddies say I need to buy ones that cost as much as $140-220 each. Will these $50 servos work well for the flight controls and throttle?

    A. Maybe. Depends how you fly. For example; a club pilot, or someone who flies the smooth schedule of IMAC type maneuvers, then yes, the DS360DLHV is a great choice. Overkill for throttle where our DS140DLHV is probably a better choice because it's faster but yes, you could use DS360 all the way around and be quite happy.

    Meanwhile, pilots flying 3D maneuvers like rapid reversal Rifle Rolls, or who like the oooh from the crowd when they hit the Wall midfield with an abrupt pull or push following a full dive into a high speed pass, then no, they're not the best choice. Not to put too fine a point on it but they're not fast enough, and won't hold up for that kind of duty in a 25 pound plane flying more than 100mph.

    So the answer is . . . 'yes, but, or maybe' because it depends on how you fly.

    • Note 1; if you could be fairly described as a club or IMAC maneuver pilot and appreciate the finer things in life, we believe you'd love the DS345BLHV instead, maybe the DS470. Especially if you actually fly the contest circuit and practice 3-5X a week when the benefits of a brushless servo pay off in spades.
    • Note 2; if you routinely perform rifle rolls and walls at high speed, the appropriate servo is the DS630BLHV - but you already know that.

    If you're the guy flying your 104" model through smooth IMAC style maneuvers you're going to love the DS360DLHV for what it brings to the table in power, smoothness, centering, and durability. If you're the guy throwing the model around on the deck, e.g. performing Harrier rolls where the wingtips brush the tips of the grass - as if it were an $80 foamy - then no, this isn't the best servo for you. Look to the DS470 or 630 because they're faster and stronger, instead.

    Q. I'm building a 120" Super Cub and powering it with a BME100, I'd like to use a DS360 on all the flight controls and a DS130 on throttle. Thoughts?


    A.
    Good choice. Exactly what I'd select for this model if I were building one. You haven't mentioned it but because 360oz-in is a bit of overkill, you can sacrifice a bit of that power by using a 6.6V A123 battery pack. This versus the 7.4V of a LiPo because you can charge LiFePO4 packs in the model (never charge LiPos in your model because of the fire risk). Anyway, I'd choose between the B2S2500 or the B2S2P5000 based on how long I intend to fly during an outing. Cubs are superb for summer days shooting touch and goes until the sun goes down, and for passing the transmitter around your pals so if it were me I'd probably lean toward the larger receiver pack.



    Q. Will a DS360 work well for steering a Traxxas TRX4?

    A. Maybe. The DS360 has the power and speed but in our opinion, not the toughness. It may work a while, but you're probably going to break it eventually. We know because while the servo is rated to 360oz-in and the gears are good to about 450oz-in, we nevertheless sell a fair number of replacement gear sets to TRX4 owners. And after a set or two they follow our recommendation to upgrade, or get POed and buy another brand. Of course we're sad to see them go (nobody is in business to tick off their customers) but the simple fact is if you've never seen what a crawler like a TRX4 undergoes in slow motion you'd be amazed the servo last for even one battery pack! https://www.youtube.com/watch?...

    Anyway, while we'll put our $50 servo against anybody else $50 servo in terms of quality and build - in all honestly - our recommendation for a TRX4 is either a DS470BLHV or DS630BLHV, instead. It's because we want you to be happy and the duty cycle for which you envision the DS360 just isn't compatible with real life. Will it fit the TRX4, does it have enough torque and speed? Yes, definitely - but - you have to remember there's a difference between theory and practice and in theory a DS360 is OK in a TRX4, but in practice it's not advisable.


    Q. I know the DS360DLHV is overkill for my Sig Kadet (a glow-powered 40-size trainer - editor) but I'm already thinking of building a Hangar 9 30cc Ultra Stick so I want to use them in this model next.

    A.
    Good thinking. Very few beginners are savvy enough to think ahead to their next model. You're showing wisdom beyond your level of experience. Speaking of experience, with it you learn your interests change over time. That, and the ideal servos for a 62" wingspan model - for what amounts to lunch money - can be upgraded to ones suitable for a much larger mode because they're the exact same size, which in the business, is called standard size. Anyway, this is the best future proofing you can make of your servo investment - well done!

    Q. I want to use a DS360 in a Traxxas Bandit (2WD buggy - editor).


    A.
    This is a good choice for bashing in the yard but once you get competitive you'll prefer either a DS305CLHV or DS345BLHV for their faster lock-to-lock (allowing you to more readily out turn a competitor). And the latter especially, for the toughness of steel gears and an all-metal case.

    Anyway, you may use this servo in a wide array of sport and scale models, with wingspans ranging from about 48" on up. And when we say 'on up', we're not kidding because the models in which the DS360DLHV may appear can be spectacular!


    SUMMARY:

    At heart, servos offering 360oz-in of torque and transiting in the 0.14sec/60° range are available from other vendors. We know that. But we also believe finding another servo that offers everything this one does is impossible. To the point we believe there isn't a better servo - for the money - on the planet. Period. No other servo offers this level of power, precision, quality, plus tank-like durability (and nobody else lets you completely rebuild them yourself).

    Better components. Better servos. The formula is simple. Decisions regarding what goes into ProModeler servos aren't made in accounting to optimize price and profit, but in engineering. This servo isn't sold for $30-40 because it costs more than that to make, but in light of what goes into it - $50 is a pretty reasonable price. Simply put, this is the best servo available for the money. Add a set to your cart. Do it now because you're going to love them!

Meanwhile, TL;DR is chock full of nitty-gritty details - where we disassemble and show you this servo side-by-side with a popular competitor. If you love delving deeply into stuff some find too tedious to read, don't overlook this tab.

    Note: operating voltage is 4.8-8.4V, but optimal performance is obtained with a 2S LiPo instead of a BEC. This is because LiPos deliver the required current without voltage spikes, noise, or otherwise adversely affecting the delicate avionics (25C or better is recommended). After all, synthetic orange colored Tang may have gone to the moon, but it doesn't compare to freshly squeezed orange juice. Same thing when it comes to feeding your avionics!

    Details count. Inside and out.


    Seeking to make a great servo for sport pilots, we created the DS360DLHV by using the case-design of our top-of-the-range DS305CLHV coreless motor servo, and matching it to a super-reliable 3-pole iron-core motor. The end result is precise and powerful - with all the nice bits of speedy coreless motor servos - minus the pricey motor. If you're a sport pilot (versus 3D where 90° throw in the blink of an eye is required), this servo strikes a perfect balance between price and performance.

    Engineered-polymer upper and lower case with brass inserts - the DS360DLHV foundation, the center case, is CNC-machined from a solid billet of 6061-T6 aircraft aluminum. Like a radiator, it keeps the powerful HV-motor nice and cool. To save weight we use fiber-filled Nylon 6,6 (an engineering-polymer like that used in a Glock handgun) because it's strong and impact resistant. And to ensure it's durable, we use brass inserts in the pockets for the steel gear-shafts.

    - Bronze inserts where the steel gear shafts ride in the polymer upper-case ensure long lasting precision gear-mesh.

    Gear train - all metal gears makes this servo strong. The 25-spline (Ø5.96mm) output shaft is Futaba compatible for convenience. Material selection makes it tough. Exotic titanium-ceramic (TiCN) armoring of the 7075-T6 output gear (same aluminum-alloy used in components of the upper receiver of an M-16 rifle) means this massive gear has an 800% increase in wearing surface hardness. Combination-gears mate C86300 manganese-bronze with 4140 chrome-moly steel for optimum strength and wear characteristics.

    - TiCN/7075-T6 output gear, plus bronze/4140 chrome-moly steel combo-gears perfectly match durability with strength.

    O-rings - have you noticed how some really expensive servos don't have o-rings? The claim is electric models make them superfluous. Since getting caught in a pop-up rain shower isn't unheard of, and re-purposing servos into a nitro-powered model a year later happens all the time . . . do you buy that line of reasoning? We figure it's because the manufacturer pockets a few extra bucks but leaving o-rings out comes at your expense. Is keeping water, fuel, and exhaust residue out of your servo important to you? Wanna know why the S160DLHV is fully o-ringed? Simply because our engineers make these decisions - not our accountant!

    - Now you see them, now you don't . . . fully captured hidden o-rings make the case resistant to water, fuel, and oil.

    Nitty gritty - it's said the measure of a man is what he does when nobody is looking - take our servo's measure the same way. Ever disassemble a servo? They typically use four long-ass Phillips head screws, which come up from the bottom, sandwich the center section, and actually thread into the plastic top-case, right? However, an S160DLHV is built better. How? To begin, we use grade 12.9 Allen-head machine-thread bolts instead of el cheapo screws. Six come in from the top plus four more from the bottom, and instead of sandwiching the center case, the ten bolts actually thread into the aluminum. The result is a far more rigid assembly that's so much better . . . it's not even fair to compare!

    - Note how an S160DLHV servo is assembled with Allen-head machine-bolts vs. el cheapo Phillips-head screws!

    Packaging - nestled within a high density foam insert for protection, each S160DLHV servo arrives packed in a jewel case. Since good looks never hurt, we use red polymer to show off our brand and laser-etched our logo into the polished aluminum center-case. These servos look great - think in terms of the fit and finish equal to, or better than, servos selling for more than $200. Bottom line? For the craftsmen who appreciates our high standards because we pay attention to the smallest detail, we hope you'll be as proud to install them in your model as we are to make them.

    - We proudly brand our product with the ProModeler logo . . . and hope you'll be as proud of them as we are.

    Better components. Better servos. The formula is simple.

    Most of us have felt that lurch of panic as we dropped a servo during installation and snatched it off the floor to inspect for damage. It's this shared experience as modelers, which led us to build the DL-family of servos to an aerospace-standard.

    For example, to better mitigate against shock (and vibration), we use what the military refer to as a conformal coating to protect the delicate electronics components mounted on the PCB (printed circuit board), Compared to the square of foam rubber used in hobby-grade servos, we call the white stuff smeared over the electronic components monkey snot because it's such a sticky mess to deal with during application. Which do you think is better?



    Anti-vibration and impact protection are a big deal to our military customers. Perhaps you aren't flying a million dollar UAV, but if you simply want better servos for your pride and joy, monkey snot is one reason they rely on ProModeler servos.

    Also important is how we use MIL-SPEC components - plus the best motors and potentiometer money can buy. These are critical for the best centering performance possible. Yet nothing is quite so telling as this simple fact . . . you can actually buy these components from us. While hobby-grade servos offer cases and gears, serious pilots appreciate being able to go a step further without returning them for service.

    Granted, sport pilots probably don't fly enough to wear them out in a decade but competition pilots - ones who get in 4-5 practice-flights 3X during the week (plus the same, or more, on weekends) can wear them out inside a year. If your winter-project list includes returning your servos for R&R, but you can make three solder joints as well as the factory technician, then you can save money. Why? It's because we know DIY is a big part of the hobby. If you appreciate being able to bring your servos back up to snuff without breaking the bank, then ProModeler servos are probably better for you, also.


    Restoring like-new performance with a simple job like replacing a potentiometer (with three easy to solder joints) while forcing you to return them for service only to charge 'almost, but not quite enough' to make it uneconomical isn't what ProModeler is about.

    Meanwhile, do you believe in better engineering? We do too. Unfortunately, unless you open it up to look after buying, the other guys don't make it very easy to know what you're actually getting. If you appreciate attention to detail, yet another thoughtful touch (one that ensure your investment in these servos delivers value) are the bronze bushings reinforcing the gear shaft pockets.

    To recap, not only is the molding for the polymer pocket more robust on our case, but the bronze inserts reinforcements are there so your servos will last, and last, and last! Bottom line? Understanding the difference between something's price and its value comes down to grokking the details.

    Along the same lines, a big difference for why experienced modelers prefer ProModeler servos and something priced about the same is found in how the center section is made. One the one had an injection molded piece, on the other one that's better because it's made of aluminum so the motor cools better when you're working the servos hard, has cooling fins for shedding heat more quickly, and is drilled and tapped to accept fine thread machine-screws for the ultimate in rigidity.



    Finally, eyeball all the major components laid out side-by-side. We suspect it's rather easy to see why your next set of servos should be from ProModeler. If you're especially sharp eyed you'll have noted the assembly uses 10 Allen-head bolts with machine-threads instead of 4 Phillips head screws with cheese-cutter threads. You'll see how each has an O-ring - and - threads into aluminum instead of plastic. You also also know to look out for gears represented as metal but which include a plastic gear so fragile they sell replacements in 3-packs. You also understand that servo manufacturers that shove a cheap piece of foam beneath the electronics cover and call it good aren't just shortchanging you, but playing roulette with your model by paying less than perfect attention to vibration protection.



    As you get a better idea of what to look for, you buy smarter. It's as simple as discerning the differences between hobby-grade and professional-grade. So let's tie it all together. Better parts. Better servos. The formula is simple. It's a no-brainer and paying the same, or more, for another brand just because it's what others do is a non-starter with savvy modelers. You've found the servos you want for your next model.

    360 oz-in servos in my 112" Extra!

    Rating:
    Pros:
    Cons:

    Several months back I called to buy DS470BLHV servos for my 112" wingspan Extra 330LT. To my surprise, after a brief chat about my flying style (smooth IMAC-type versus 3D-maneuvers), they recommended using DS360DLHV servos, instead. I've now got enough flights to say they were right. These 360oz-in servos have plenty of power and speed so I'm happy to recommend them for sophisticated pilots into precision maneuvers. Plus, considering I was prepared to spend $100/servo, I'm blown away they cared enough for my interests to help me save money by guiding me into a servo costing half as much.

    • None so far!

    I own a heavily modified Axial Yeti 4x4 rock racer. As it goes in the hobby, every performance gain exposes other weaknesses. The steering on the Yeti was very sloppy in stock form and only got worse. With larger tires and the stock steering and suspension components completely replaced with stouter aftermarket parts, the stock servo became the weak link.

    While searching forums for a better replacement, I was introduced to ProModeler. I read the impressive specs, and for the about a 1/2 of the price of a comparable servo I decided to give them a try. I'm glad I did! I went from poor control (and frequent crashes) to outstanding control. Steering is now precise and importantly, return to center is fast and accurate. I added a Castle BEC to the Yeti for steering and run with no issues. Slightly taller than stock, I did have to shim it and it was a tight squeeze into the compartment.

    The ProModeler servos are high quality units. They also look great. I am installing another one today into my Axial SCX10 rock crawler and will soon replace the servos in my RC boats with DS130DLHV.

    I purchased 9 ProModeler DS360DLHV servos. The quality and workmanship is simply outstanding.I also ordered ProModeler CNC-aluminum servo arms and they are great. I've also introduced a couple of my friends and flying buddies to these servos and they absolutely love them (one put them in his 93" AJ Laser 230z). And I replaced the servos in my 105" AJ Laser as well. I fly mostly IMAC maneuvers and I love the smooth and predictability of these servos. If you try them, you will never go back to whatever you use now. Finally a businessman who is honest and will not sell you something you really don't need! I appreciate that and I'm sure you will to.Oh, and did I mention the great pricing and the outstanding customer service? I will certainly be a continuing customer and will spread the word. Great work!

It has been winter time, plus I'm putting them in a new build so I can not comment on performance in plane in the air - yet. I also took one servo apart to compare to pictures online and they are identical. Holding power of these servos in outstanding.

    Cons:

    I just ordered 6 more of these as I am currently converting over all my giant scale planes to this servo exclusively. I wanted you to know that every word in the description of these servo rings true down to the very last detail. I’ve been modeling since 1978 and have used lots of servos over the years but these guys really are very underrated. Servo overkill is a marketing hype that’s hard for some to overcome. I bought a set a few months ago to try out and see just what a 50 dollar servo can do. I must say I’m sold for life. I fly IMAC, pattern, high energy 3D, Cubs, gliders, so I like it all to some degree. I decided to install these in a brand new AJ 115” Laser230z 40% and after almost 50 grueling flights these dudes are just as they were when I put them in. They are just a little slower than what I’m accustomed to due to the motor used but they are so darn precise I simply cannot tell the difference in using these versus $150 servos. I've always wanted a universal servo for all my airplanes and it seems after 35 years in giant scale I’ve finally found one.
