    Order this servo and receive a DS555BLHV - keep reading . . .

    Note; we have deprecated the DS470BLHV after a long production run in favor of the DS555BLHV (555oz-in - 0.06sec/60°).

    RECAP:

    Developed initially as a 420oz-in brushless servo for our lead non-civilian client nearly a decade ago, ongoing iterative improvements saw it achieve many firsts on its way to becoming the popular DS470BLHV. Things like steel gears, bronze hard points in the aluminum, and conformal coating on the PCB (permitting it to handle more torque and live longer in high vibration environments) were first introduced in this, our top of the range unit. And it led to gaining converts from other brands.

    Meanwhile, it's been unchanged for the last three years, but because our competition never sleeps, then staying a step ahead of them means our research never stops, either. While this led us to introduced both the DS630BLHV and DS930BLHV (at necessarily higher price points), now we've circled back around to the DS470 and have improved it yet again, resulting in the DS555BLHV. The best part is, this time along with a bit more torque you also get more speed.

    Significantly more speed. Enough to outclass the DS345BLHV (a great choice of helicopters, mid-size 3DXA models, and 1/8th scale racing) meaning we're deprecating it also. Anyway, through the end of the calendar year, 12/2020 (giving us time to create the DS55BLHV product listing), orders for the DS470 will receive the DS55BLHV (we're done making more DS470BLHV).

    Bottom line? The king is dead, long live the king . . . the DS55BLHV. So while the DS470 is gone, please don't mourn it because this one's better! And by the way, the fact it's stronger and faster means you can install it on a 2-servo wing panel (one a DS470 and the other a DS55) and never notice a difference because it'll be a transparent match since it can keep up with the old one in both torque and speed.

    Moreover, you'll find the DS555BLHV is a worthy successor because we've retained all the good points that made the DS470 such a winner - like bronze hard points for the steel gear shafts, 13 o-rings for sealing, conformal coating of the PCB . . . and all whilst keeping costs in check!

    DISCONTINUED: DS470BLHV

    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!

    FAQ

    Q. Is it normal for the ProModeler DS470 to get fairly warm, almost hot to the touch, after 25-30 min of crawling? I set my endpoints after I first installed making sure no binding was occurring.

    A. If there is no binding, no problem . . . and yes, it's going to get hot - of course! For example, depending on how hard it's working you may be dissipating 35W, maybe more. Ever touched a 35W light bulb? Burned your finger, right? The formula for power is W=V*A so plug in for Voltage, make an educated guess on Amperage (if you don't have an inline meter), then solve for Watts. Presto, you get a lot of heat! The point is, you can't get 470oz-in of force without a lot of power. Power means heat. Always has, always will.

    Q. Sometimes when I rotate my DS470 back and forth by hand (with the power off)it reaches the stop and then gets stuck and won't move. I've never had a servo do this before, do I need to return it for service?

    A. This is not unusual with the DS470 and doesn't indicate any fault. It's a trick of the gear ratio and the servo motor. If you've ever spun a brushless motor by hand you'll recall the feel of 'cogging' as it hits the poles of the magnets. What's happening is the stop for the servo works because of a pin in the output gear (we bore the gear and press a pin into place designed to hit a mechanical stop. However, what may happen as you turn it by hand (which is a bad idea anyway because you're forcing it backwards through 402:1 gear ratio using gears with tiny teeth), anyway, what happens is you hit the stop and this happens at about zero velocity. So what with four gears in the gear train (consisting of meshes between 8 working surfaces), is it may occur between teeth, or really close, and what with the backlash (for gear sets to work, even if they're the transmission of a million dollar Formula 1 car, there is a certain amount of backlash because it's the nature of how gears mate) plus the need to overcome the cogging in the motor itself is it gets stuck. The solution is to apply power and let it center itself - and stop forcing the gears back and forth manually! You don't want to get in the habit of doing this because it's not how servo gear trains are designed to work. Anyway, this won't ever happen under power, and during use . . . so there's no problem!

    I love these servos!

    I've waited till I got some experience before reviewing because I wanted to check wear. While a lot of servos are great new, they loosen quickly but after more than 50 flight (35% Slick 580) the DS470BLHV servos are still great. I love these servos! And support is excellent. For example, I had some initial issues with the servos acting 'jittery' when the engine was running'. I called and spoke with John and he pointed me to an ignition issue and it turned out to a worn spark plug caps on the high tension of the engine's ignition that was generating a bit of stray RF. New caps, and the problem went away.

    Great steering for twin 91s

    • No cons
    • none!

    I've been racing RC boats for 40 years and one of my top boats, which runs in Multi Engine Hydro with two 91's for power weighs 15 lbs, and steering servos are a problem. On a friend's suggestion I purchased DS470BLHV for rudder, the DS90DLHV for throttle, and DS100DLHV for mixture.


    Just powering up on the bench I could tell the difference right off the start. They were very smooth and quiet, so off to the lake we go. Fired up the pair of 91s on 55% nitro. Boat in the water and with ProModeler DS470 servos for steering, DS90s on throttle, and tiny DS100 micro servos on mixture the boat was driving straight and great. Never had a boat drive this smooth before. Exit off the turns was true and straight. No course correction was needed. Clocked with radar at 88 mph. Took home the hardware in 1st. These motors turn about 23,000RPMs. One run was about 15 laps. On our course 2 laps is 1/3 mile so 6 laps is one mile. This was a full fuel load of about 48 oz. total of fuel.


    I like the way the boat ran so well the next week I ordered more servo's to replace the ones in another boat. Guess I'll be replacing servos in all of my boats as I get to them.

    A great product. Wanted a servo 'for life' that I can install, use, bash around and it will always work. Bit early to tell but this seems so far it will fit the bill . . . and the customer service because of working direct with ProModeler is 2nd to none. They treat you like you're the most important customer in the world . . . the way it should be!

    There are servos out there that look good, and there are servos that go buzz buzz and move back and forth pathetically. Then there are ProModeler servos. These look better than your wife and they are twice as quiet. If you want a servo that can kick your ass in an arm wrasslin' contest then just shut your mouth and send John some money. You'll only be disappointed if you are a genuinely miserable person who is expecting some sorta noisy stuttering hunk of garbage that can't hold a straight line.

    I was looking for a nice high-quality servo and this one caught my attention so I wanted to try it out for my TRX-4. This servo has great torque and is incredibly strong. My Traxxas TRX-4 has been in use a great deal in the very harsh and cold northern environment of Finland and the servo still held up. I highly recommend this servo to anyone who wishes to use their crawler in the most rugged and demanding environments. Thumbs up!

The Kraton drives/steers so much better now, my biggest regret about paying as much as I did for this servo is that I didn't make it my FIRST upgrade. Won't make that mistake again. Awesome product, you guys nailed it! This is a killer servo! Top notch quality and performance.

    I found out about these servos from some people online. I was pretty apprehensive at first. After receiving the servo, I installed it in an all metal Axial Bomber RR10. Vanquish Currie Rockjock axles aluminum 2.2 beadlocks wrapped in ProLine TSL Super Swampers, Mamba Monster X 1/8 scale ESC with a 3800KV TenShock sensored motor Running a 3s Floureon 3000 MaH 30c battery.

    I ran it with a metal servo arm and promptly went to town beating the hell out of it. Cartwheels, 6 ft. in the air jumps, creek runs, hill climbs whatever i could do to it. After about 2 months of abuse I had my first failure . . . but it was the aluminum servo horn splines, not the servo. I sheared every one of them right off! They were all still stuck inside the teeth on the servo! It happened on pavement and was a one front wheel landing after an air born cartwheel. The servo was fine and had no issues whatsoever.

    Since then I have installed a Proline Big Hit servo saver and beat it some more. It has seen a years worth of Bomber bashing and now it has been transplanted into my RC4WD Beast 2 but just until I can get the next size up for the Beast. Special thanks to John Beech for being such a great guy and bringing a level of pride, professionalism, and excellent customer service that is rare today. I will never build without ProModeler again!

    I saw this servo being discussed within the RCU forum and decided to try one. Then I was so blown away with how smooth it is - and that there's no noise - that I got four more for my Pilot RC Predator 2.2 (plus another four for my Top RC Odyssey 2.3m turbine). But beyond the servo quality, I've also been extremely impressed with the level of customer service.

Running on a SCX10ii with a Hobbywing AXE system that has a internal BEC at 7.4V it holds so rock steady I blew a panhard mount out in no time. A nice new aluminum one and its been good since. I also did an aluminum servo mount while I was at it, you could see the stock plastic one flex under pressure. This servo is 470oz-in of greatness!

    I purchased this product for my Traxxas TX-4. This servo works really well with crawlers. Has Plenty of power. If you are going to be using this servo for another crawler then you are in fantastic hands. This is top of the line. The quality of the product is freaking on point. It looks sweet right out of the box. There is one thing I did not realize when I purchased this. You will possibly need an extra battery or BEC to run this setup in your crawler. It takes a little know how and somewhat of a hassle but boy o boy is it worth it. Overall great product, great customer service, and excellent experience.

    I have not opened up the case, so I can not comment on the inside construction. But the outside construction is beautiful. CNC, all aluminum case. (6) Allen bolt screws top and bottom WITH rubber washer. I mean, they really look like a nice piece of tech. They center perfectly. I mean PERFECTLY! I really like the 25 T output shaft. It makes it easier to get geometry right. I also like that the servo arm screw is an Allen head, not the dreaded Phillips head. However I WOULD appreciate an Allen head with a bit more depth to it. These low profile screws can easily be stripped where the Allen tool goes into the head. Overall, I am impressed with this servo and happy with my purchase!

    I did a lot of research into steering servos for my RR10 Bomber. Of course I looked at torque and speed but also power requirements of the servo and power limitations of the rest of the system. On paper the 470 had it all and was the most effecient. Having been an engineer for a defense contractor, I am very familiar with the requirements of MIL - STDs and testing. That convinced me that these servos HAVE to be good so I bought two, one for me and one for my brother.
    The purchasing experience has been a pleasure. It's refreshing to do business with a company that understands Customer Service. I received the servos in 2 days in spite of a hurricane.
    I've just begun to use the 470, but so far it's very powerful, quiet and looks amazing (although I would prefer a brushed aluminum finish.) I will not hesitate to purchase this servo again.
