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.

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).
- 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 crawler, or flying off water with a float plane. It's why these tests are important for civilian users, also!
Serious modelers - whether they're flying precise maneuvers, or working a technical section with a crawler - 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 ell as 1/10th scale crawlers and rigs. 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!
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.
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!
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
This customer is often a highly experienced modeler,
but also includes savvy beginners who realize just because the servo

when you transition to a higher performance model. 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!
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). So if you're
an experienced modeler, and if you are mechanically 'ept' this is yet another consideration (presuming you can do
basic soldering, but naturally, you can also send them to us for R&R if
you aren't comfortable doing these things).
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!

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

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 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.
