I hear they are horrible. They are said to be the worst servo ever made. The ones sold today are a clone of a clone of a budget servo no longer made. Look at this You Tube Vid:

Haha, that answers that one then thanks for the link.

As another question then, can anyone recommend a reasonable priced one available in the uk?

What about the HD servo that's offered on EZ Robots web store? I know it's not shipped from within the UK but it will arrive at least as fast (maybe). They ship from China. I've had several shipment from EZ Robot's China shop via DHL and they have arrived here in the USA in less then a week.

I love the MG995 servos. They're fantastic and I have never experienced an issue with one. :)

How do these look? Mg996r's?

http://bit.ly/TUqMHL

Looking to control 2 omnibot 2000 arms, and pan tilt for the head.

I use the Mg 995's for the arms on my omnibot and they are plenty strong. I have not any issues with them either.

The 996's are great too. The price makes them ridiculously useful. And if you ever break one, its little financial effort to replace. I have bought expensive servos in the past, and they broke. That's a real kick in the face when an expensive servos dies. So now I use popular and affordable servos :)

DJ...i could not agree more, I like the MG995 too, i plan on using them on my next build of a Quadruped no problem for a budget servo, if you are expecting high end performance you can always go with high end servos like Savox, but it's unfair to be expecting high performance and quality from a reasonably cheap servo.

Well, I'm not disputing the experience behind the answers given but I'm now confused. Most Google searches returnednot so good reviews on this servo. Is there more then one manufacturer of these? Here's another detailed review:

on 11-22-2005 XJet posted the following on the RCUniverse RC Radio Forum:

"I've been checking these servos out and can report the following:

1. they are very torquey -- I haven't measured the torque yet but it may well be the amount claimed.

2. they are quite fast, perhaps as fast as claimed -- again, I've yet to actually measure them.

3. they are all metal geared -- even the gear driven from the motor shaft appears to be metal, unlike most other MG servos which use a nylon gear at this point in the train.

4. they do appear to operate with a higher motor drive frequency than a regular non-digital servo so may well be digital.

5. the servo-amp is not well matched to the motor/geartrain/feedback pot. In essence, this mismatch manifests itself as significant overshoot when the servo is repositioning. This is to say that if you command the servo to move clockwise to a position, it will actually move past that position (by 3 degrees or so) then move back to the correct position.

Even more strangely, if the servo is at rest and you try to move the arm, it actually moves towards the pressure being applied.

6. resolution is "okay" but not as good as most other brands of digital servos and there are even some good non-digitals that are better.

7. without a servo -arm, the weight is 2oz exactly, not the 1.78oz advertised.

8. these servos adhere to Futaba standards (spline and direction) but come with a JR/Hitec connector.

9. physically, the assembly leaves a little to be desired. The PCB on all the units I inspected was incorrectly inserted into the case so that it was sitting on an angle rather than square to the bottom (not a biggie but perhaps indicative of a lower QC standards?). The feedback pot and motor are connected to the PCB by wires and dabs of glue support these wires only where they mount on the pot. The wires to the motor are unsupported and will almost certainly break through fatigue over time if the servo is exposed to moderate or high levels of vibration.

So is this servo a bargain or a bust?

I guess it depends on your expectations.

If you're looking at it as a sub $20 budget servo then it's not bad at all. You get what would appear to be a bullet-proof metal gearset, a supposedly coreless motor, a digital amp and plenty of torque at a faster than average speed.

However, if you're planning to compare this servo to something like the Hitec HS5945 (digital, coreless, metal-gears which sells for around $90) then you'll be disappointed. Its' when put alongside a "quality" coreless digital that the MG995 shows that it really is a low-cost servo. The quality servos have a markedly better resolution, are rock-steady when repositioning and don't even budge when subjected to load -- all areas where the MG995 suffers.

The ultimate test however, is how do they fly?

I threw one on the rudder of my Katana 3D plane (replacing an HS5925) and I did immediately notice the slower speed. The plane also felt less "solid" in rudder response during knife-edge and in a hover -- but the Hitec certainly wasn't over four times better (as the price might suggest it should be).

If you fly iMAC or turbine-powered models (where precision and reliability is of paramount importance) then I strongly suggest you stick to the more expensive options. However, if you just want a bullet-proof servo that has a snot-load of torque and costs little more than a standard servo then these are worth a look.

I would strongly recommend however, that people take a moment to drop a dab of hot-glue or acid-free silicon glue on the motor leads -- just to pre-empt the inevitable."

Hope is is some help.

Cheers

I would not recommend this servo for high precision control of rudders for flying planes. For robotics they are great!

I agree with DJ. If a servo dies on a robot there isnt much chance of it hurting the robot itself. However if it fails in a performance RC plane.....tragedy! The financial loss can be huge.

I have both 995 and 996R servos but I havent truly put them through any tests.

Thanks guys. It's really great to get everyone's opinion. As you all say, it's not like most of us are building precision instruments, so finding a source of budget servos you don't mind replacing if something does go wrong is such a useful thing to have.

I've gone with the lot of 4 MG996R's I found on ebay, so will see how they go. I'm sure they will be perfect for the job.

Thanks again
