    Outputting 470 oz-in and transiting in 0.091 sec/60° the DS470BLHV standard-size digital servo is well suited for 150-200cc powered IMAC aircraft from the likes of Carden, AJ Aircraft, and Extreme Flight as well as rock crawlers like TRX4 and Wraith II.

    Initially created for our military and industrial UAS customers (primarily drones with infrared sensors for pipeline inspection as well as LIDAR equipped sensors for ag work), civilian users include professional builders and competitors on the lookout for an edge. Offered for your consideration, this brushless digital servo will deliver roughly 30 pounds of force, and do so very, very precisely.


    This is a hotly contested class with competitors offering servos with similar output. Examples can be found made by the big 3 (Futaba, JR, and Hitec) plus a host of newer players, like MKS, BK, and ProModeler.

    Once you get into the target range of 500oz-in (about 32Kg-cm) we all fine tune things with gearing. Obviously there's a direct trade-off between torque and speed. For example, you can either opt for a bit more torque at the expense of speed, and the corollary, more speed in exchange for some torque.

    You want this servo because it's better. For example, unlike hobby-grade competitors, these are hand-crafted to meet MIL-STD-810G-Part 16 (Vibration) Test Method 514.6 as well as Test Method 516.6 (shock). While it's unlikely the frame of your model will ever transmit jolts to your servos like those imparted by impacting 20mm rounds, modelers know all about crashes and engines vibrations. This alone is reason enough to want this servo.

    Of course, delivering munitions on target isn't of keen interest to professional drivers, either but the durability of this servo is a big deal. What makes it ideal for the torturous duty cycle involved in crawling a 15lb rig over rip-rap an agile man could only traverse with difficulty - and at the risk of breaking an ankle - is a case CNC-machined from a solid billet of 6061-T6 aircraft aluminum. But there's more because the pockets where the steel gear shafts fit have been bushed with bronze to enhance durability!


    If you fly IMAC maneuvers, then 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!



    Once professional builders began using these servos for their discerning customers, and as competitive pilots attending IMAC events used them, then because these guys practice at club fields across the country, interest surged because sportsmen discovered them also. And amongst the especially attentive ones - for whom thoughtful touches like Allen head bolts instead of Phillips screws - was important, our reputation grew. If you have an eye for detail, little things like these are signature characteristics that differentiate ProModeler servos from the rest of the pack!

    Incidentally, this is the 5th iteration of this popular servo. We now consider it a fully mature product. Meanwhile, yet another example of how a ProModeler servo is the one you want is found in how it's protected from vibration. Competing servos depend on a little square of foam rubber sandwiched between the PCB and the bottom cover (to isolate the guts from vibration). We use an aerospace conformal coating instead (we call it monkey-snot because it's such a sticky mess to deal with and apply).

    We also pay close attention to things like dust, water, and exhaust-oil resistance. How? Through the use of 13 O-rings for sealing. Why so many? It's because truly protecting the insides from the environment means using there must be an O-ring everywhere, at the splined output shaft where it exits the case, where the three case components come together to become one, and even beneath the 10 individual screw heads!

    For example, what if while you're flying a pop-up rain shower develops before you can land? Or maybe you love to fly off water! This means protecting the servo's guts from the environment is important, right? After all, we know how pernicious water can be with respect to getting inside the servo. And this is important for all users . . .even if you never intend to take your servo underwater! But if you do plan to play submarine, then read the askJohn article regarding how to make them more water-resistant with a couple easy steps.



    Better components. Better servos. The formula is simple. Decisions regarding what go into ProModeler servos aren't made in accounting to optimize price and profit, but in engineering. This servo doesn't cost less to make than our competitors, it costs more. The reasonable price is due entirely to a better business model. One that eschews the old way of doing things (importer + distributor + hobby dealers) because they all get a cut (at your expense). With us, you're the one doing the cutting . . . because you cut these middlemen out of the deal in buying direct!

    Bottom line? These servo make good sense even if you 'are' made of money. But if you're on a budget, then many modelers consider them a godsend!


    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!

    Bought two of the DS470BLHV servos - so far. Love them! Running them at 7.4V on a pair of rock crawlers. Both weigh 15 pounds. By comparison, I bought a Protek R/C T150 for my 3rd crawler (at 13lbs it weighs less but it soon burned out). Highly recommend the DS470BLHV instead. install, adjust, and never have any issues.

    Works great!

    I bought my 1st servo from ProModeler for my new TRX-4 kit build after reading comments on some on-line forums. I may be new to crawlers, but I've been building, and racing, RC cars for nearly 35 years so let’s just say I have installed an used a fair amount of servos over those years. The 470 oz. servo I purchased is second to none in quality. Partly made in the USA and priced very competitively with the other major brands, the specs absolutely destroys the competition. I'll definitely be buy again for future projects. Well done!

    This is my first aftermarket servo and I couldn’t be happier. I’m running it in my Vaterra Ascender and it’s working perfectly. It’s very strong set at 7.4 volts through a BEC, and could go to higher voltage but I’m more than happy with it where it is. It throws the truck around if you get the wheels in a bind and doesn’t even think twice. I’ve ran it through some shallow water about 3-4 inches and works perfect. The best of all is it’s almost silent! If I need another servo, another one of these is what I’m buying.

    When I decided I was going to build a So Cal Monster Trucks Warpath monster truck to compete in the Trigger King Series, I knew I wanted some serious servos to complement the awesome chassis. After doing some research I came across the ProModeler DS470BLHV servos. The specs looked great, so I figured I would give them a try. Man, am I glad I did. The combination of speed and power is exactly what I was looking for. The fact they look awesome is just an added bonus!

    Servo on my heavy scx10

    Cons:
    • Power hungry needs bec

    Putting this servo on my Axial SCX10 with the stock AE5 ESC didn’t really work that well. It was really weak. Called ProMolder and they suggested the BEC wasn't inadequate. After a little time and research discovered the AE5 is only good for 2A and 5 volts. Installed a proper BEC and this really brought this thing to life. Love it now. Very fast and strong - and I have very heavy rig and tend to beat it up pretty hard - not really anything unusually to roll it down a 30 foot rock face. Going to order another one soon for my Wraith. Oh yeah plastic servo horn don’t really work with this servo on a crawler. Striped 3 before I had to make a trip to the hobby shop to pick up a good aluminum one.

    My "go to" waterproof steering servo

    I have been into RC for a few years and recently started enjoying RC cars, both for bashing and in the last 2 months for crawling. I had previously bought high-end servos from 2 other manufacturers to use as steering servos in 1/8 scale monster trucks. Both perform great! When I got into crawling, I realized that with all RTR vehicles the steering servo is a weak point. I stumbled upon ProModeler after reading Facebook posts in a group I belong to and purchased a DS470BLHV for my Traxxas TRX-4 on a whim. Well, I can say that the reviews on this site are spot on. The servo is dead quiet, very fast, and strong enough to power through anything I have attempted so far. From an aesthetic point of view, these aluminum servos are gorgeous. I enjoy expertly crafted things of all sort and this servo just looks and feels like a fine quality piece of engineering art. I bought my first ProModeler DS470BLHV servo less than a month ago and have already purchased 2 more for a Vaterra Ascender and RC4WD Marlin Crawler. The servo I have in my Arrma Talion costs over $230 and it is amazing, but if I had to do it again I would get a ProModeler and be done with it. If you are looking for a solid product with world class performance that is backed by a small company that clearly cares about it's product and the RC model community, I recommended that you give ProModeler a try.

    Been running this servo for a couple weeks now and it performs as expected. I've come from savox and man this servo even under binding (setting end points) it's extremely quite and powerful. It exceeded my expectations and it even took a couple dunks fully submerged under water. I like to test the limits and she fell in the deeper part of the rocks I was crawling that was under water. Will be getting one soon for my 8th scale!

    I purchased the DS470BLHV for use in one of my rock crawler chassis. I have always used Savox because of price needs, but this one fell right into my range and I wanted to try it out. I am so impressed that i will be switching as many trucks as i can to this servo. It's not as noisy, has great power, looks amazing, and the koozie they included was an excellent touch. I have used it for almost three weeks and can not say enough good things about this servo!

    As soon as I placed my order I received a phone call from ProModeler. They informed me that there was a faster cheaper way to ship my servo, and indeed it showed up on time.

    I am a newbie to hobby RC trucks and this is probably the best purchase I've made for my truck (Vaterra Ascender). Hooked right up no issues and programming went smooth. I can't express how fast and strong this thing is and looks beautiful, SO SHINY.

    I had only heard great things about ProModeler and was told the 470 is "Bulletproof". Right out of the box you know you've just bought something special. I love it! ProModeler has my business for life!

    The first review I read was written by a good friend who introduced me to hobby scale trucks. He is hard on equipment. He hasn't broken one years past its warranty. So glad I got this for my truck.

    After failures from several other brands doing rock crawling competitions, rock bouncing, and bashing I decided to give these servos a try. I have been extremely pleased with the performance. I am an experienced hobbyist with many RCs, and these are the best servos I have ever had. I bought 2 on my first order and since then have ordered 3 more. I am converting all my rigs that demand high torque servo's to ProModeler. Great Product!

    I purchased an original S420BLHV years ago. I have been running it in my Axial Bomber. It performs flawlessly in many conditions. When I purchased a Traxxas TRX-4 in spring 2017 I knew I wanted a servo that would perform in a competition setting as well as relentless weekend abuse. With the DS470BLHV I have had nothing but worry free crawls. The torque and smooth action makes precise tire placement a breeze. I can't say enough good things!

    I had been looking for a steering Servo for my Traxxas TRX-4. There are many servos out there that are better than the stock Servo. I chose the Pro 470 because of its power and build quality. The machined aluminum case looks great too. I would absolutely recommend this Servo to anyone wanting to upgrade the TRX-4 steering Servo. I used a Samix aluminum horn and both were a quick drop in replacement with no modifications necessary. I used the Traxxas link and iPhone app to quickly set the endpoints.

    Best servo for the buck

    Rating:
    Pros:
    Cons:

    I've been playing with trucks for over a decade now. I consider myself to be a bit hard on equipment, especially electronics. I have three of these servos, plus three of the older generation servos. Short story is they outperform my Hitec 7950's and I can't seem to even kill a one. It's pretty rare for me to have a servo outlast its warranty period, so for them all to continue to function flawlessly is pretty amazing. I run them in "rock racers", like Wraith, Bomber, Twin Hammers. All with solid steering links, aluminum horns, and often times being driven with reckless abandon. I've bent Vanquish steering arms, ripped apart RPM variants of Revo rod ends, and even bent an axle housing with beef tubes inside. Yet the ProModeler servos soldier on!
