Yeah they are a bit more than say Savox, but so far I am loving the Xpert Servos. Put the PI-3431 in my PRS1 and it is great. Super smooth and no more receiver cap or that annoying buzz.

After replacing 2 gear sets in the last year in my Savox 1258 I put the SI-4431 one in my EB48 and have to say I am loving that one as well. More torque and more responsive.

Can't go wrong in my opinion. Also I will support the brands that support racing here in the Northwest. Xpert is sponsoring the NCT series out here!

for the impression I was able to get of the servo I had before selling the warranty replacement, the physical build quality looked good and off of the 6V battery pack did some testing with on it, it seemed to be quite powerful. It also had a very smooth feel to it. This was a WR7701 servo.

The only comment I would make and this would go for any electronics, if you notice anything odd happening with your system, stop and contact the manufacturer right away. Do not believe it is something "one off". This can be an expensive and time consuming lesson to learn.

Through it all Nick provided great customer service, a real bright spot.

That WR-7701 has monster torque, plus it can handle up to 8.4V, so deffo NOT a bad piece of kit to have in any model. I just ordered a WR-6601 the other day and that as well can handle up to 8.4V, but I'll only put 7.4V into it, since that's the maximum voltage the onboard BEC output can be for a Tekin RX8 ESC as I'm sure tons of you guys know already.

Granted, the WR-6601 and WR-7701 are slower than the WR-4401. Not sure if it really mean that much for 1/8 scale buggies, if they are a fraction slower or not.
Not sure what I'll do with the Savöx SC-1258TG i'll be taking out of my DEX408 buggy, if I should sell it, or put it in one of my other models.
I'll probably put it into my Compagnucci 1/8 gasoline model. I won't hear the noise once that baby if fired up. Plus I have wanted to get a servo with decent torque and speed for that model for a good while now, so seems to be the perfect time change the excisting servo.

Yeah my original plan was to use it in a solid axle truck for "mud / snow" running hence why I wanted monster torque as well as waterproof. The 6601 model though interested me as well and i was considering that for my tekno et48 which would have been the next model to be upgraded to Xpert servos if things had worked out better with the WR7701.

But from what I have seen, others are having a blast with them and they look to be good. Just bad luck I guess. Just wish it wasn't $100 over the cost of the servo itself to find out. :lol:

one thing I would love to see in servos in general would be some form of a plug and play servo wire so you can lengthen and shorten with a quick swap.

They showed the RS series servos with that feature a while ago but I haven't heard anything about them recently.

that's really cool. Be curious on fitment if they go with that setup on say a Tekno vehicle based on how they servo is mounted.

But still very cool.

Hitokiri_2000 03-27-2015 11:59 AM

Wouldn't it be easier to just make the servo wires your self? You could cut the wire on the servo 2 inches from the servo and then put a plug on it and make what ever length servo extender you would require for the model in question. I make my own servo extenders and it's easy with the right tools.

Hansen Hobbies have all the things you would need to get started like wire, plugs, pins and tools such as wire cutters and the special pliers needed for crimping if you don't want to mess with a soldering iron.

Cain 03-27-2015 12:06 PM

Nothing is as easy as plug and play :)

Hitokiri_2000 03-27-2015 12:50 PM

I make my own Plug N' Play hehe

Cain 03-27-2015 12:58 PM

yeah I think the big advantage to setup like this is if you damage a servo wire in a pinch you can quickly change it out.

Hitokiri_2000 03-27-2015 01:16 PM

True and that's why it's nice to be able make what ever length servo wire you need.

Hitokiri_2000 03-29-2015 11:31 AM

Shown below: I Just installed an Xpert WR-6601 servo in my Durango DEX408 V1 buggy
http://billeder.bazoom.dk/rc/album/7...-dex408-v1.jpg

Shown below: Making sure it get's a constant flow of maximum juice at 8.4V I also installed a Castle Creations 10Amp BEC.
http://billeder.bazoom.dk/rc/album/7...-dex408-v1.jpg

Shown below: Though maybe difficult to see properly, are some of my own servo extension cables. Going into the RX the connectors to the external BEC, ESC and servo is sort of hovering above the servo it self. Maybe even harder to see, is the extender for the ESC you can see only the black and white cables is used as the red needs to be inactive for the external BEC to do it's job properly. So if you look closely at the first plug going into the RX you will see what looks like a hole where the red wire would go into the plug.

I am considering buying a 7701 servo for a Wraith. For those that have one, what have your experiences been?
Cain- I saw some posts of yours, do you still have your servo? did your issue get taken care of?
Any info would be great.
Thanks

I received a NIB servo in return, but I didn't feel comfortable using it so I sold it to recoup some of my losses due to having to replace an out of warranty ESC it apparently killed in addition to several replacements it killed as well. I can't imagine what would have happened cost wise if I had tried hooking up to other ESCs I had here that are out of warranty to but work fine.

I do believe i probably had a one off issue however, but what I wanted to use the servo for (winter snow running in a monster truck) had the time to use it pass. So I sold it to someone else who could use get more use out of it.

Maybe down the road I'll give it a look again as some of the other servos have specs I like, but I will make sure I only do that with an esc still under warranty. :lol:

Are you considering getting the waterproof one or just any of the 7701's?
If you indeed want to have it in the waterproof edition here is one place you can get one http://www.xpert-rc-us.com/product-p/wr-7701-hv.htm since it's sold out at Amain.

mkl 04-08-2015 07:11 AM

yes, looking for a waterproof servo. They show out of stock on that site as well. I contacted Hobby Authority, the US distributor, and they said that the 7701 would be back in stock by the end of the month.

That is a really high price even with the coupon. They are $99 everywhere else, even from the distributor.
I can wait. Thanks for the tip though.

Cain 04-08-2015 07:19 AM

mkl are yo ulooking to use it in a MT or a Truggy?

If a Truggy I would maybe give the 6601 version a look for a bit more speed as the torque is already way up there.

I am planning on installing it into an Axial Wraith. I want to do some crawling and trail running with it. I won't be intensionally submerging it but there are creeks and puddles that will be obstacles. So I don't necessarily need the fastest speed, but high torque would be nice. I think the 6601 would cover my needs in both departments, but more is better right? The consensus seems to be that anything over 300oz is fine in the Wraith.

Cain 04-08-2015 08:22 AM

yeah I was going to use it in a Kyosho Mad Force that I have for sale now and was thinking the same. was to run through snow, etc and i liked its high voltage option. Was between this and the Airtronics 94671 and figured save some money and give it a shot, plus was supported by Nick which has been a pleasure so figured give it a go.

Hitokiri_2000 04-08-2015 10:18 AM

For the Wraith, which is not a speed machine if my intel is correct, the WR-7701 will be perfect. It will have massive torque, if provided with enough power. A small tip would be to get a Castle Creations 10A BEC and programming kit for the BEC to ensure the servo will have a nice steady 8.4V supply.
you won't be sorry.

That's what I have done to ensure my WR-6601 get's a steady 8.4V supply in my Durango DEX408 buggy. Not as fast as the WR-4401 but more powerful.

I have the WR-4401 in my Hong Nor Nexx8 buggy, which i'm getting ready for some fun. A CC 10A BEC will be installed in that as well. Ensurering a steady 6.6V power stream, so I will get maximum steering torque.

mkl 04-08-2015 11:10 AM

I agree, the BEC is basically a necessity in a crawler. I ordered one with the Wraith kit so it will be going in from the start.
Thanks guys.

Hitokiri_2000 04-08-2015 01:17 PM

Show us the Wraith with the new servo and other goodies once you have assembled it. :D

mkl 04-08-2015 02:05 PM

Will do, I'm excited about it, It's my first foray into this segment of RC.

I didn't realize you were looking at the water proof model. Yeah those are 99.00. The link I sent you was for the full aluminum case model.

Here is the waterproof model http://tqhobby.com/index.php?route=p...87&search=7701

Coupon code 10percent for that 10% off!!

As stated above HAD is waiting for a shipment. I am waiting on a few back orders myself ;)

Hitokiri_2000 04-12-2015 11:55 AM

I made a short video of my WR-6601 servo if those of you who don't own one would like to see one being fired up.

After countless attempts of making the youtube thingy working to no avail I'll just post the link.

That "Someone Else" was me. I have had Hitec's, Futaba's, Savox and Jr's in my Heli's and Planes with zero issues even after Lawn Darting them. I'm not a racer but I have had Hitec and Savox in my SCX10, Wraith, Yeti, Rival and Losi 8T with zero issues. I built my Yeti XL and wanted to try a new servo and found Cain's Xpert WR7701 for sale. Fit the bill so why not give it a go. I have it only running 7.4v through a CC BEC and this servo throws these giant tires around with some serious authority and speed. I can't wait to bump up the voltage to 8.4v. I'm looking to get an MT4G3 and will put in an Xpert WR7701 without hesitation.

That's one nice looking machine you have there, not a bad place to play you have found either.
On 8.4V you will have torque in your WR-7701 to tip over a tank hehe.

glad you liked it. I wish I had that luck with my original purchase but sometimes things happen.

12th scale WGT servos
 
Hi,

What servos are recommended for 12th scale or WGT on road cars?

Thanks Greg G

Hitokiri_2000 09-16-2015 10:39 AM

Does it take a standard sized servo? If so then you won't need a super strong servo. A super fast one would probably be the best choice.

What sort of electronics do you plan to use apart from the servo? I'm asking to better help in recommend weather you should get a LV or HV servo.

If your ESC gives out 5.5 to 6.6 Volts the SM/SN-2201LV could be a good choice, they are super fast and relatively strong with the 7.40 Kg's of torque.

Remember these arent cheap. But if you ask me, well worth the coin.

Bubonic-X 09-16-2015 12:24 PM

Are the servos with the detachable wire harness out yet?

Cain 09-16-2015 01:57 PM

winter is upon us again, and I am thinking of trying another waterproof setup for some fun running.

Need to get in touch with Viper as if I use there ESC, I don't want to run through what I did with the last servo and more so, it killing a perfectly fine ESC and having to pay to fix it.

Anyway, anyone have experience with these with the new Mamba ESCs?

I will say, looking back at the videos I took of the issue are quite comical lol

Greg - Xpert does not have one right now -- but with current 1/12 (and multiple) World Champion Marc Rheinard on the team --- chances are they will be working on one.

Drbrake 10-08-2015 08:35 AM

Put one in my new B5m factory lite
blazing fast and very good recentering forces

5tone 10-08-2015 12:32 PM

can you give us some details on the model you get in your b5m
is it fit well, get a good alignment between servo horn and steering ?
i need a new servo and be very interest by xpert ones.

thanks.

4WD Buggy
 
Howdy, I'm wondering what you would recommend from the xpert range for 4WD buggy.

I run a PI-3402 in touring car and I'm quite happy with it, I notice Naoto is using one in his ZX-6 this weekend. Many others are using KO RSX low profile servos as well.

I would have thought something standard size would have been typical, but having two servos the same in both my cars would be a real bonus in terms of backup.
