I think several different companies sell this servo. This is a 35 kilogram, high torque all metal gear servo, and this ought to be pretty nice 35 kilogram. That should be pretty good. It comes with this, as you can see different servo horns in this bag, and it comes with a stain, i believe, that’s, a stainless steel, servo horns let’s go ahead and take it out of the bag and look at the contents here. Of course here is a servo and then you’ve got this bag here of the different servo horns you want to put on there for whatever you’re going to use it on. Of course, most of us, like myself, are going to use it on an rc car, and then here is that metal one inside of here so pretty inexpensive like again, they sell these on amazon and it should be a good high, torque servo, because what i thought I would do is, since i was offered to review this. This would be perfect to upgrade the steering servo in my dhk maximus, so that’s the best way to really go about reviewing this the weather. Here you know we have quite a bit of snow. So i’m, probably not going to take the truck out. I’Ve done some snow run videos with the maximus, and it does very well but we’ll just put this in the car and just make sure that it works. It should be perfectly fine and it will be a nice upgrade, because a lot of people complain on the maximus that the steering servo is this weak link.

And the steering servo is right down in here, and this is obviously pretty heavy to get in front of the camera. But hopefully we can see it right down here and it is only a 9 kilogram steering servo. So it is what like a fourth of the power of this uh, one that i got to review here. So this ought to make a nice upgrade to the truck. So what i’m gon na do is i’m going to take out the the steering, servo and then we’ll put this one in so one second, how i get that all right guys, so i have the camera repositioned slightly here and what it appears on the maximus here. I got to get the dual dean’s plugs out of the way here you take off these. These allen, wrench or hex, screw heads here, there’s a couple on this side and there’s one over here. I think there’s must be an adapter underneath here and it should allow us to come out. I don’t think you have to take anything out from underneath, but i could be mistaken. I believe these just you know like a standard servo screw into these little mounts here. On this on the side, so what we’ll do is i’ll go ahead and take these out and see if it does come loose. Of course, we want i’m going to just use the steering horn that comes with this one, so that it works fine rather than switching it to that metal one.

But this should be perfectly fine. I’Ve not heard anybody busting the link here, it’s more the servo itself, either strips out and just it doesn’t quite have the power for this really large 1 8th scale truck with these really big tires and that’s. The reason why now i’ve had no problems, but since i was you know, offered to review this might as well go ahead and upgrade this servo with a more powerful one. So i’m going to do is go ahead. Just pause! The video here and i’ll. Take these screws out and make sure it comes undone rather than just sitting here and fast forwarding through a bunch of stuff that you guys won’t, want to watch i’ll be right back okay, so i went ahead and just took those screws out on the top, and I did have to take out. I did take off this to the bottom. I believe i had to get that off to kind of get this out from underneath here, because it’s wedged in between this piece. So i need to take this little piece that attaches a chassis to be able to attach the new steering servo in there. Then it just pops right out so it’s a matter of taking out two screws on the bottom and then two on one side and one here. This was a total of five screws. I took off and then we off just go ahead and unplug it from the receiver over here.

Pull this down the wire. I probably just do that right now now i’ve upgraded, the steering. Excuse me, the receiver and the uh controller on this to the radio link. One has a built in um gyro in it, so i did the dhk. I never really cared too much for the stock radio system. It wasn’t bad in terms of distance or anything it just. I don’t like that that weird notch in the steering wheel on it and stuff like that, so the radial link, one with the built in gyro, really helps on a truck like this. That really the you know how it can get squirrely on you with where the wheels and tires balloon up on it when you’re driving it so it’s good, just see if we can get this pulled out here, and it made it to where this is made. To go, you know this. The uh servo plug go right through there, so yeah go ahead and take that out and i’ll just have to uh we’ll go ahead and put this one in there, let’s go ahead and uh undo the uh the tie and put the feed this one through let’s See it should be probably going to go like this, so it’s, like the other one we’ll feed it in through here and then go ahead and attach it. So let me just go ahead rather than you guys watch me. Do a bunch of fumbling around here.

We’Ll! Go ahead and i’ll get that stuff on there and then we’ll put the screws in and get the servo here mounted into the car. So i’ll be right back all right, guys. I’M back, i can’t believe what a pain this is trying to be just to replace or uh swap out. This steering servo there’s. This little piece up in here, which is gon na, be difficult to see in the video that attaches right up in here and it’s got two screws that latch the servo mount from the coming in from the bottom from the back here it screws up into it. I was able to pop it off when i pulled the servo out, but i can’t push it in and snap it into those screws. It’S going to be hard for me to explain and it’s certainly very hard for you guys to see this and you can access those screws to tighten them through these two holes that are in the bottom of the car right and here i believe, it’s right. I think it’s these two and let me see, is it those two i think so and you can reach up in there and and from these you know these holes to tighten it, but you can’t get. I couldn’t get it on with the screws back down the snap distribution from the side and to try to screw it in there it’s darn it impossible to try to get your finger put as you can get a screw up there and hold it in place.

So i figured what can you come in through the screw holes and then feed the screw up on top of the allen wrench and tighten it well, these holes are just not quite big enough. The screw the screw head gets caught in there. So what i think i’m going to try to do is just take a drill and i think itself to see which two holes it is again, but it doesn’t really matter and just widen the hole a little bit so the screw can get through there. And then i can tighten it because i can’t get it through there. I think, coming in from the bottom is going to be the easiest way to try to do this unless there’s something i’m just overseeing, because i i can’t get the snap on to the screws from the side. Obviously i was able to get the unsnap by pulling really hard, so maybe it’s possible to basically you’re taking the well here’s the old servo. You would take in these servo mounts here and you would. The screws come up like this and when i, when i took it off, i popped them off, but i can’t push it back on there. So the screws need to come up from the bottom and tighten so again. I think i’m going to have to try to widen those holes in the chassis and then in that uh in the alloy come up there and then see. If i can get the mount so hopefully i’m able to do that because i’m getting a bit frustrated, even nicked my finger there just messing around bleeding pretty good.

So let me try that out guys and i’ll be right back all right guys. So i went ahead and drilled those two holes a little bit wider and i got the steering servo in here. It was just a pure lock till i hit the hole. Let me show you again, i’m, even pointing to the two wrong holes. While i go but it’s these these two holes right here, i just widened a little bit so that the screw would in the head would go all the way through and since it’s attached to the top of my allen, wrench i was able to then you know, It’Ll stay on there pretty easy until you reach all the way to the top, and i just started turning and i got pure luck so i got i got it tightened up there. So then, at that point i went ahead and put the uh this adapter piece back in some of the things that take it off here. Maybe you don’t need to take off. You know um, but because this thing this piece here in the front, you could probably just take the two screws off the bottom and it would it it might lift out with the servo but it’s a little peg down here that snaps it into place. So it lines up with the holes, so i got the two screws up to the bottom and the back got the two here now. I just need to put the servo horn on here and tighten that down and get some more screws i took out like i said i may have taken some screws.

I didn’t need to – i really wasn’t sure so i’m going to do that. Then i’ll get some batteries they’re not charged up, but have enough power just to test the steering servo so get that hooked up and just see how the steering works. It’S, probably a good idea to uh power it on and make sure that the servo is centered. Before you put the servo horn on because if it might be out of whack and then you put it on there, you may have to take it off and reposition it or something if your trim doesn’t have enough. So i may go ahead and do that. So let me go ahead and power it off and get those screws back in electricity hooked up to it and then we’ll see how it works. I’Ll be right back all right guys, so i went ahead and i just centered the steering um the servo and the one i put in with the power and then i went ahead and put the servo horn on and tightened it down and should be good to Go so this is powered on it’d, be a little noisy because of the esc and the fan on the motor here that uses to keep it cool, here’s the radio link and turn it on, and there we go guys. Don’T even have to do. Servo’S all wired up right now, i don’t have to reverse it or anything so yeah. Now i get a 35 kilogram.

High torque servo in here and uh shouldn’t have any problems with it stripping out the metal gears and certainly it’ll, have plenty of torque. For these big wheels so a little bit of a pain there, guys with the uh getting the servo mounted back in which you know again, i maybe there’s another way of doing it better. I just drilled out the you know: just widened the holes a little bit on the bottom, so i could feed the screw up in there. I think what you could also do is you probably could widen the little gaps on the side of the servo, so they snap in to the sides of the screws and then you have to make sure tight. They get tightened up and mashed up they’re good. So they don’t pop out the sides. So that was what was my next attack a plan. A plan of attack was just make the little gaps a little wider on the sides and then you’d be able to uh, probably snap it on to the post of the screws, but wide nose of the holes was not. It was very minimal amount. I took off and now i can feed a screw all the way up from the bottom. Alright guys that wraps up the review of these 35 kilogram, high torque servo and slash dhk maximus steering servo upgrade video. If you like these tutorials or my reviews and flight videos, whatever be sure to subscribe, give me a thumbs up, because that’s really important to youtube.

I don’t get many of those and i’d like to get more, so give me a thumbs up if you don’t, like it, give me a thumbs down whatever just give me something. Also comment: if you have any questions, let me know if there’s anything that i need to change and prove anything you want to hear anything about.
