seen somewhere about MG995 servo from Tesla?

I had seen a post where someone was recommending buying servos MG995 from a place in Michigan. Like Testla, tesla electronics. Anyone remember this. I can't seem to find the company that sells them.

I haven't use them a lot, probably 8 or 10 so far. The ones from the place that I was looking for are better quality. I use them on my bigger planes, big bingo, 1/4 scale cub and Freedom 3D. Just can't remember the place that I purchased them from. Someone on RCU recommended this place I am looking for.

I was just wondering if you had used them with success. I had 4 of them and they tested fine. I was only going to use them on throttle, for my gas engine planes. I mentioned it at the field, and someone sent me a link to RC report where the guy did a review on them,after reading the review, I sold all 4. I also did a google search, and wasn't happy with what I read. I know there's alot of them on ebay, and they go fairly cheap.

I have heard that about some of the mg995. The ones from this company are suppose to different and it is identified by a red spot on the bottom of the servo. I have not had any problems with the ones that I have. I have been using them on ailerons and rudders. of my bigger planes. Maybe it is just a sales job by the company that I am looking for.

I can't see how they'd be that much better, since the problems with the original are that the gears are too heavy for the motor to handle and the wiring is flimsy. Seems that an upgrade from such big issues would make for a model name change.

The MG995's are from TowerPro/Hextronics in China.
There are or were several variants of these servos.
The latest is the MG995R's

These are fairly strong standard servos.
I don't know where the info about the gears "being to heavy for the motor" came from as the servos are rated for 10KG/CM of force... or 138oz/in. There is NO WAY the gears are "too heavy for the motor" if the effective torque is in this range ( which I have tested ).
In opening them up, I find nothing flimsy about the wiring, though I did see a discussion here about some having poor junction solder points. That may have changed.
Jester_S1 have you tried them?
I have used about 24 so far with great results.
goirish you may also want to check out the HD servos in this torque range. They are also now being sold in the U.S. by companies such as Troy Built and Chief Aircraft. I use these on my 50cc planes and above....
BTW: I've used the MG995R's on 50cc planes as well... I put them on my 50cc CMP Edge 540T.
The plane will SCREETCH when I perform a hard pullup at speed, or a hard roll at speed as there is no blowback on the large surfaces.

goirish do a google search before you try the HD stuff also. Check the RC report, that guy is straight up, if it's junk he calls it junk, he may have done a review on the HD servos also, not sure.

I didn't either,actually haven't looked. Also he doesn't do reviews on all servos, but you can find some reviews here on RCU in the club house radio section on the HD servo. If he hasn't done a report on the HD line of servos, send him a donation, and request him to do a review on them

They were mentioned in one of the issues. It wasn't a full review, but they seemed to look somewhat favorably on them.
I'll have to go through my PDF issues and see if I can't dig it up.
I just saw a thread over on the Flying Behemoths forums where they seem to like them a lot.

No, I haven't used any of them. Here's where I got the idea that the gear were too heavy.

I had 4 of the MG995's and not one of those suckers would stay centred without load. I thought it was because of the inertia of all that brass inside, the mechanics just kept overshooting. On the ground they would whine and then start swinging wildly from side to side. One of them just stopped working after 2 minutes of this. But then it would work again after a while. Just what you need when doing your ground checks.
The wire was heavy duty, the soldering was rubbish. The feedback pot was an open carbon type, only any good for setting the volume on a child's toy radio (IMPO).
I consigned all 4 to the bin.

Ya all may want to check the MG996 as they seem to be a step up
My 2 cents worth
Im going to try them in some of my Skydivers as of now im using Traxxas Revo steering servos at 105 oz the 956 s have almost as much and about 1/2 price

The guy was correct in complaining about the fraying wires... but the "unsupported wires"... from the controller board to the motor... c'mon...
He needs to get a bit real... he's talking about a 1" length or less... SHEEZ!
The motor should never move if properly mounted, nor should the circuit board. That would have been a much better and more important point of review. What does he think would happen?
Those broken wires were NOT the result of vibration, rather a bad joint and a poor assembler craming things into the case.
I would be far more worried about cold solder joints, poor soldering, poor deadband or recentering... etc.
IMHO He's focused on the wrong thing..
I haven't seen ANY "overshoot" problems even with the older servos.
The gears simply do NOT have enough inertia to cause the problem he has stated...
A lot of what he is saying is pure speculation...
While I've used a bunch of the servos on different planes as well as the newer ( and better ) versions.
I've seen others target the actual problems and benefits correctly elsewhere.
I agree with those negatives and positives... e.g. centering is not as precise as more expensive servos, etc...
But for a sports flyer most of the problems are non-issues... and the later version addressed this stuff anyway.

I'll have to disagree with that TimBle, actually he stated just exactly how cheaply, and poorly the servo is made, the reason's why the servo is junk, and so forth. He didn't pull any punches, told the truth, and plainly, and honestly explained,and showed why the servo was junk. opjose states ( He needs to get a bit real... he's talking about a 1" length or less... SHEEZ!) apparently his chinese engine/engines don't/doesn't have any vibration at all. You can put an R, and X, or even a Z behind the 995, and it's not going to change this servo.

Well I'll have to defer to those who know more than me on whether the review guy is right or not, but the bottom line for me is that I don't trust shoddy products. With modern manufacturing, anybody can build an electronics product that will do what the box says when it's new. It's 5 years down the road that the difference between a $20 item and a $60 item shows up.
