    Outputting 470 oz-in and transiting in 0.072 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. 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.

    ue, we judged getting transit times into the 7s was a worthy goal compared to our previous generation, which was in the 9s. 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!



    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!

    Very happy with my purchase! Opened the box and saw a beautiful servo with quality and craftsmanship second to none! Very strong servo turns my Super Swamper XL tires (Interco) on my 9 pound RR10 Bomber (Axial)with ease. I definitely recommend this servo and I going to get another one to put on my TRX4 (Traxas). Bottom line is, you can't go wrong with this servo!

    I have nothing but awesome things to say about this servo. I was blown away with the attention to detail and strength of this servo. it is beautiful and strong. i had my car under water for VERY extended times and never lost steering or got an ounce of water in it. all my previous servos fried almost immediately. it does not twitch or squeal like other servos. i will be replacing all my servos with these from now on.

    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!

    ABSOLUTELY LOVE THIS SERVO! Running it on my Yeti XL and night and day difference. Turning is MUCH tighter and has much faster response with plenty or torque. You will not be disappointed!

    You cant get a better quality high torque servo! I'm now using these in 4 different airplanes! One is a 110" wing span Extreme Flight Yak 54 where instead of two I'm able to just use one servo for the rudder! The post sale service is second to none, and the quality is top notch. These are servos you could easily spend $250 each elsewhere!

    This servo just keeps going and going!

    Pros:
    Cons:

    I use the DS470BLHV in my comp crawlers. They get the workout of a lifetime during every use. I'm a sponsored driver (but not with ProModeler because they don't sponsor anybody) and I regularly push my rigs hard. This servo has never failed me. Not ever. I'm not saying it's unbreakable because nothing is, but this is a very good quality product that's taken the place of Hitec HS-7955TG servos because these just don't break. While I hate to say it, I love these things because I don't have to carry an extra servo. Hit up YouTube - https://youtu.be/N0EMIK1np4Y - to see for yourself. I recommend to others as the best servo available hands down!

    My Composite ARF 2.6 meter Extra 330 SC is powered by a DLE 120. Jeti radio system. ProModeler servos throughout, which are spectacular! Flies with crisp servo response. No slop on the control surfaces. The best centering I’ve ever seen!

    These servos KICK BUTT

    Rating:
    Pros:
    Cons:

    Just got back from the field with my 118" Carden 260 and these servos KICK BUTT. I’ve also got a Carden 300 equipped with JR 8911HV and it’s nowhere near as locked in (and I thought it was a great set up until today). When you neutralize the sticks, the 260 stops like you flipped a switch. It locks in like nothing me or anybody else with me today has ever seen! I'm very impressed with these servos and can't wait to go back out to fly!
