20KG RC Servo High Torque Servo Motors, Waterproof Full Metal Gear Steering Servo for 1/6 1/8 1/10 1/12 RC Car Robot DIY, Digital Servo with 25T Servo Horn, Control Angle 180°

works well

Very nice geared

Very strong servo had a large turning radius and fit in my Traxxas rustler perfectly and had no problem fight the pressure of turning at 50+mph (had a lot of power) definitely would recommend! the noise however was very loud but didn't bother me much with the cover on. control was great was able to move very fast to where I wanted it to go! and the 180-degree turning range was just amazing, again would recommend!

Great replacement Easy-to-install, fits good.

I guess I got a bad one. On my servo tester, which works as expected with 4 other servos I have, this one did not responds as it should. I have never seen another servo act likes one did. When doing a full sweep it would very slowly rotate, one step at a time and take almost 2 minutes to rotate about 150 degrees, then it would quickly rotate all the way in a fraction of a second, just like all my other servos do. I tried different voltages from 5 to 8 volts and two different servo testers with the same results. Sometimes, if asked to move by a small angle, say 10 degrees, it would behave normally. However when asked to move 30 or more degrees, it went into this ultra slow step-by-step mode. I was monitoring current and voltage (HP power supply) and it wasn't drawing excess current or causing a voltage dip. I have no idea what it was doing in its ultra slow mode. It was as though the controller was telling it to rotate by 1 degree every second or two - but it wasn't. All my other similar servos rotated normally. It looks nice, it arrived quickly wit all the advertised accessories. It just didn't work right. I returned it for a full refund. No problems. I didn't try a second one and if I had, maybe I would have gotten a good one?.Who knows. Butthis one was a dud.

Great servo, high torque, waterproof. Durable a little heavy for me, but works great. Great value! Highly recomended

This servo is strong enough to delete the second servo on my old Traxxas Revo 2.5r truck! I found that replacing the stock servos with just one of these, the steering response is much faster and its got way more torque than the stock cheapo plastic servos that the truck came with. Only problem in doing this, and I can't say if it was my equipment being faulty or just not compatible with this servo, was that the Traxxas receiver would only control one servo, it would not control the throttle servo any more. Put the old servos back in the rx and all was working again (albeit, stripped for the steering, which is why I replaced it in the first place!). Rather than downgrade to replacement servos from Traxxas, I just decided to buy a whole new radio system (see my other review on the Flysky FS-GT3B radio), bought another one of these servos for throttle, and with everything installed, the Revo is working better than it did when it was new! Time will tell on how long these servos will last, but for now it works just fine! If they do give any problems, I'll update my review.

* Setup the servo - can't just write servo.write(0) with this digital servo, have to use for loop as below. * LD-20MG by LEWANSOUL .. analog SG90 does allow that. Also, needs external power..I used 5vdc 2.4 amp wall wart. Must connect negative to esp8266 ground for it to work. I used a nodemcu 12e board. *********************************************************************************/ servo.attach(12); //D6 for(i_Pos = 130; i_Pos>=0; i_Pos-=1) { // goes from 180 degrees to 0 degrees servo.write(i_Pos); // tell servo to go to position in variable 'i_Pos' i_Val = servo.read(); Serial.print("i_Val = "); Serial.println(i_Val); delay(5); // waits 15ms for the servo to reach the position } Update...did run into reliability problems until I added an adjustable boost transformer to take input to 6.6vdc

HIWONDERはロボットを作っている会社で、ロボサーボの実績はあると思います。 当商品はスピードこそ若干もっさりしているものの、RCに使うのであれば、ビッグタイヤ系やクローラー、復刻バギーなんかでは不便のない速さです。またトルクは申し分なく、ダートや深い落ち葉、芝生や草むらなんかも、ステアリングがもっていかれることもなく、しっかり切っていけますね。 サーボもメタル仕様で丈夫な作りです。その分、重量があるので、少しバランスには影響あると思います。 このHIWONDER社に似たサーボもありますが、商品の質はこちらの方が良いと思います。

It's not bad. My beliefs are it is not as powerful as it says but for the price... satisfied

良い

SANWAのSRM102と比べてスピードは少し遅い感じですがトルクは格段にあり、サーボホーン側からは軸は動きません。コスパのいい商品だと思います。耐久性や耐水性はまだわかりません。。

岩場や泥でもパワフルでトルク負けしません。2Aのbecで全く問題ありません。センターもズレがなく、安定動作しています。有名メーカーのサーボでなくても全くよし。
