350kg High Torque RC Servo, 16V24V High Voltage Full Metal Gear Digital Servo (Control Angle 360)

I have three of these servos, and they're very, very powerful. Crazy amounts of torque, and easy to set up, overall. The physical design is nice, with good placement of bolt positions. Pretty accurate in positioning, too.I wish they had a different and more-rugged power connector, though.One caveat: They're powerful enough and fast enough to be moderately dangerous. Make sure to stand clear of them and _keep your hands away_ when they're powered up. You can limit their arc and initial position easily enough, but if you moved the controller position while they're turned off, they'll go to the new position right away, at full speed and power. I ended up including some physical stops for the lever one was driving, and used a belt drive (that can slip some) for another.For the price, you won't find another servo with more power and features, especially in this form factor.

Bought this for a holding mechanism that needed precise control - and the ability to have usefulness in other areas (servo or regular motor). What a great product and excellent seller! Definitely watch the video on the last image of product description (explains light codes, setting, etc). Also, note that for direction control in motor mode, use PWM with the following logic:0-49% = motor goes forward50% = stops (holds position)51-100% = motor goes backwardsUse direction toggle to switch these.Great value for the money. Will continue to be useful and last a long time.Seller also responds quickly to emails - so don’t hesitate to contact them with questions!

I am building a large (5 foot tall) robot for Halloween and needed a way to rotate the head (a 16" plywood cube). This easily handles the job and is far more powerful than the strongest 1/5 hobby RC servo that I could find at double the price. It also has a D-profile 8mm output shaft which is much better for high torque applications than a 25T RC servo output. I really like the manual potentiometers for precision adjustments of center point and range. Mounting this is easy as well. Lots of holes with pre-molded nut retention, etc. The plastic housing I believe is glass reinforced nylon so is very strong.

Wanted more power, I believe they sent me a used one had scratches all over it, returned it and got the more powerful one, works great

I got two of these servos for a hackathon project - that meant i had to get these up and running correctly ASAP. I was initially unsure about which size wire to use for the power, so I called customer support and somebody picked up one ring in. He helped me with that question and others, and emailed me some other helpful resources, which is better customer support than 99% of large companies I've ever had to interact with - shoutout Eong!Super unique servo, love the look and sturdy feel and can probably be used for any project where you need a very high power, compact, and easy-to-use servo (I'll definitely be recycling mine to use for future projects).

I'm very happy with these servos but there are a few things worth noting.First is the speed.I've used a lot of much smaller servos before and typically they aren't very fast, these servos on the other hand are extremely fast, do not get in the way of whatever you have connected to them!To slow them down I had to inject delays between pulses like this...void loop(){for (int i = 200; i < 400; i++){pwm.setPWM(0, 0, i);delay(10);}}This works fine and allows you to fine-tune the speed by playing around with the delay value.Second, as previously mentioned in another review the power connector is reversed from the standard config. No problem if you are building your power cable but if not it could be a serious problem.Third, the power connector they use works great but it adds maybe 5 or 6mm of overall height when the power cable is plugged in, something that wasn't mentioned in the ad or reviews that I saw.If you have plenty of room above the servo it's not an issue but in my case, I had to get creative to make the servo fit in the space I had available for it.Lastly, another reviewer stated that the mount used non-standard hardware, on the two that I received the mounts used standard M4 hardware. They did however allow for M4 nuts to be used on both ends of the mounts, if you use M4 bolts this might be fine but I use M4 button head screws and had to put M4 washers under the screw heads to keep them from being pulled into the mounts.These small issues are why I gave them 4 stars instead of 5.

I purchased one of these DOCYKE servos to use in industrial automation. I hooked this up to a test unit that outputs a PWM signal and the unit works really well, and very accurate. Soon I will test for durability using about 50% of its continuous capacity. I consider this to be a really great solution because it is compact, easy to operate, and it is very affordable.

Took it out of the box and tested it. It seemed to work fine so I attached a plastic rod to measure the angle and it wouldn't turn on again. I heard something rattling inside. I turned it over and out fell what looked like a resistor from the circuit board. It started working again, but I don't trust the soldering on this and I assume other parts will start falling off once the return period is over so I'm just going to return it now. Seller was willing to replace it, but I just don't have confidence in the product anymore.Edit: decided to test it some more before returning it. It doesn't move for anything less than 2 degrees of difference from the current shaft position. The description claims it had 0.3 degrees of accuracy so thats another reason not to keep it.
