The length of the arm makes a HUGE difference on rated torque. The closer you measure to the output the higher the torque. The Mfg claim never mentions the testing length of the arm. 22mm is the standard arm length(hole center to hole center) on most Crawlers from my experience.
Sure they give a measure. It's right in the rating. Kg.cm. Force exerted in kg, 1 cm away from the moment center.
torque[Kg*cm] or [N*m] (don't mind oz/inch stuff, it's just ridicolous) so you have to measure it 1cm away from the center of torque.
Plus you must measure it in the direction that's ortogonal to the torque. This test is totally inaccurate.
@@Rusty-Metal wasnt it further than 1cm from the shaft tho ? look like 2.
I find that even though the zoskay servos are overrated, they're very good for the price. I got the 35kg one for $30 and I can't really complain. It's plenty fast at 7.4 volts and has plenty of power for any 8th scale basher. Fairly durable too even though I'm running a very tight servo saver setup. Plus it's one of those servos where if you bust it up, it won't cost you a fortune to replace. I managed to finally kill my 25kg zoskay servo (which is why I have the 35kg one now) after running oversized tires and lawn darting multiple times, torquing the servo pretty hard. It only damaged one of the gears though.
*Edit* well, I must say, the servo was great, but it ended up dying on me. Thought maybe it was a fluke so I tried another one, and that one died on me as well. Worked very well and was consistent for a few months, but it couldn't handle the abuse my outcast 6s went through. If you have a lighter 3s or 4s vehicle, it would probably be alright for the long hall, but definitely can't recommend it after having two of them die. The 25kg zoskay seemed more durable than the 35kg in all honesty.
Mind blown. I'll have to assume your servo arm is exactly one inch? Here I am doubting your results because I have 3 of the JX servos! I just watched your review of the Holmes v3 and on the same outfit his numbers were true, so kudos to John. I will say that the JX's have ample torque in my trail trucks and the steel gears are available separately for a reasonable price. I'm done with aluminum gears 'cause they get sloppy too fast. This series of videos will become a valuable reference guide for consumers, thanks for the effort. Maybe when you've done a bunch, a playlist would be useful as well?
These tests are very much appreciated!
Would love to see the speed tested as well, as there`s a direct result of pulled amp`s (power/energy), and speed (gearing) that makes the max torque. But i agree the amps + torque tells us enough for deciding.
It would be nice to see this test with the new Zoskey 25kg and 35kg Pro versions. They claim much more speed and actual torque. To see how they have improved their products
I stumbled across this video before I realized it was you. Great video Francis! Thanks for making it.
Straight to the point, no messing around, thanks!
Wow. This is really a slap in the face. Especially with that 46kg servo. I just ordered a jx eco boost 35kg. I hope i dont regret it...
Thank you. Another good test.
I have two 46kg Servos steering my BC8 Mammoth. Someone ask if they make that much power. I told them "No...they don't. If I was to guess they are making about 350oz of torque....which is fine".
I spent $50 a piece for them. I run the at 8 volts through the Mamba Monster X.
Funny...is was almost spot-on in my guess.
Appreciate that share. They're not bad values. Just bad against claims. They seem to be fairly dependable too.
La informacion de capacidad de torque de los servomotores es a 1 cm del punto de giro, a medida que se aleja esta distancia el servo pierde fuerza , en este caso es lo que se esperaria, ya que la medición que se hace es a aproximadamente 2 cm del punto de giro , habra una perdida del 50 % del torque
The torque depends also from the distance among the center of rotation of the servo and the position form wich the arm is positioned. can you tell me wich is this distance
Thats why its kg/cm or oz/in. E.G: if it says 35kg, that means that 1cm away from the horn, it will lift 35kg. 13.88 is the magic number at converting between the two measurements.
I have two of these 35kg DSServos in my E Revo 2.0 and this test confirmed my suspicions. 😏
Since I first wrote this I have replaced the esc with a 7.4v capable one and that gave the servos more life + got rid of the brown outs I had with stock esc.
I'm running the 20kg zoskay on my carpa rear axle on the half inch hole... on the 3/4 inch hole which gives full lock to lock it actually did fine but I was getting too much rear steer. It was sluggish and slow and would stall time to time at 3/4 hole. On the 1/2" hole it rarely stalls. Sometimes it'll push the back axle away from the object. Pretty happy with it's strength and steering angle in that position... especially since it was $18. I run the 2250 trax-ass blue servo up front. It sucked on my TRX6 even stalling on carpet. It did not like a 10 1/4 pound truck lol. So I put in a reefs triple 7 which is extremely strong, fast, and quiet; and the 2250 went onto the Capra where it has no issues and is actually very good. It's definitely stronger than the 20kg dsservo, and I'm about to up the voltage from 6 to 7.5, even though the cheap servo is only rated to 6.8, when I put in my micro99 servo. Or perhaps I'll keep it at 6v. Wish the mamba x could go between 6 and 7.5v.
It'd be nice if these manufacturer's watched you're videos and decided to put honest ratings on their products
If we're able to affect the industry and influence servo manufacturers to be more honest, that would be a nice accomplishment. Nobody needs to get duped.
RC Review this is why I use your amazon links when I purchase am item based on your reviews. You are really performing an essential service to the RC community
It's weird how varied everyone's tests are I've seen a ton of videos testing these servos and every video the servo testing machine says different torque
I just got the JX Servo 46kg and I’m putting it in my WlToys and it seems Pretty Powerful
I'm really curious on how well the JX servo finds center everytime? Running 1/8th scale buggy and truggy, and building an budget build. I am really interested in the Servo finding center everytime.
The PowerHD higher prices servos are strong, but finding center is not true all the time. So what I wanted, they failed.
Great work! Thanks for testing and documenting!
Thanks again!
Love the servo testing
Wow! Not as much power with the ZOSKAY as I thought!
Interesting versus the more expensive servis also.
Great info man. 🍻👊 Going to continue to watch these as in the market for a new servo for my TRX Sport. Everything else runs a Savox 1230, interested to see it when you get to it. Claims 500oz @ 6volts. We'll see soon enough, works great out crawling, and a good value at $72.
thank you. Yes, more coming.
I only get the $30 Amazon servo to put in as a spare in emergency. Just in case. Otherwise, spend the $100 or so and get a better servo. Some deals out there so maybe grab two good servos over time.
Finally a test on a servo I have :)
Great tests. Pretty much confirm most of what is out there in all products. With a few exceptions you usually get what you pay for and that is usually fair. Reputable companies that spend their time and effort on QC and development make better products but have to charge more. On the other side...just shows that most of us don't 'need' the best stuff for average use and we're happy with spending less on things that claim more because it still fits our needs. These have almost all still been significantly better than most stock servos.
It sucks when lies leads to sales and Amazon pumps them out to everyone looking for a servo. We all suffer and so does our great hobby.
Not to mention all the honest manufacturers who lose so much business since buyers flock to these servos with false claims.
@@RCReviewChannel Totally agree. There needs to be a far better level of honesty across the board so we can understand what we need/want and select a product that meets what we expect.
Excellent video as usual. Thank you!
Awesome 👍♥️🧡💛💚❤
The JX 46kg servo was a favorite, but I'm disappointed it was double the fake specification.
I thought it was a fake specification to some extent.
Thank you for doing these honest tests!
Yes, sharing is caring!
I noticed in the specs that the rating is determined at 1cm and your test look like about 2.5cm.
I would like to see you run three of the same servos just for fun.
I would guess the cheaper servos would be all over the place but the more expensive would be more consistent.
It wouldn't hurt to check the calibration of your rig with a pulley and weights.
They should test the savox 2290sg and the protek 370tbl servo
We have both and are done with the testing. Just gotta edit.
@@RCReviewChannel cool I just want to now which one to buy
Thank you for all those servo tests. Any chance you measured the both X-maxx traxxas servos to see if they are up to the specs? 2085 and 2085x
Really valuable chanel !
If You want to be on date in RC world!
Thanks for sharing and keep coming!
Excellent info Francis. Very disappointing to see how overrated these servos are. My Enduro is very heavy. I'm about to order the Boom Racing Python servo, it's mounted on the axle rather than chassis. I'll see how it compares to the DS3235 i'm using at the moment!
Very intelligent way of measuring power.
This force must be measured with 1 cm from rotation point. You use much longer.
In the US, we measure in oz/in so exactly 1 inch away from center and we measure in ounces.
To get kg/cm we use a perfect math computation.
We appreciate the info.
@@RCReviewChannel WRONG our not testing them correctly bro'
So the Zoskay 35 Kg has the same torque as the Power HD 20 Kg at 6V.
Any plans on testing Futaba a700?
Love your channel. Yours for real info, and Kevin Talbot for fun stuff.
Question I have is, how much do you need? I have one of the cheap 25kg Zoskay on my SCX10.2. Metal beadlocks, 40g wheel weights, big mudders. I've never run into a situation where I don't have enough torque to move my wheels, nor do I feel I need more speed.
I don't mind paying more for quality, but so far I can't see why I should when it comes to crawler servos.
If you haven't bound your servo yet you haven't tried hard enough. 😏
@@667Gurba hah ok fair enough. I'm pretty new to crawling. When that happens I'll look at getting something better.
I'm new too but have discovered that rock crawling requires more power from the servo than I imagined. The stock 15kg sound adequate but only for trailing. I use a Protek 370 that is supposed to have 45kg@7.4v. It barely binds. Only when stuck between rocks.
Yes another servo test video!
The JX is often recommended 🤔
I assume the distance between the servo center and hole position is one inch, is it correct? Thanks for taking the time to do a very clear and objective test.
Yes, correct. Always 1 inch.
Hay una formula matematica que describe aquello
What servo do you run when you switch out the factory one. In a large 1/10 or 1/8 scale vehicle?
Please please please help my JX digital servo DC6015 32kg is not wanting to turn on the top of my survey what do I do
Please test the PowerHobby 300BW. This servo looks like a good servo for planes. and is cheap.
Thank you for the excellent video.
Can I use this 35kg servo for my TRX6 with a 3C 11.1v lipo battery?
can you run the HD 20KG servo on 7.4v using the hobbywing quicrun esc
We need some 3S testing on these cheap servos.
do you think it is ok to operate the BLS-HV7146MG with 5 Volt?
I love your servo testing series. Great job. Any chance to test the Protek 370TBL ?
yes, coming today!!!
Would the Zoskay 35kg benefit from the traxxas external bec? Running stock electronics on trx4 kit version
If that’s the 45kg servo wouldn’t it mean it’s stronger than that brand new reefs 777 servo?
Can you recommend a good servo for the x-maxx? Was looking at the jx but search for something else after seeing this
I'm new to rc cars, I have a kyosho tki3, which servo would you recommend? Another question are all servos the same for all rc cars?
Really enjoying these tests,please test the Savox sw-1210sg waterproff servo as its a crawlers servo and not cheap.
Checked old video's and you already tested the savox 1210sg and it did really well as i thought it would.Just run mine on 6v with just the micro x castle esc in a scx10ii and it works great.Thanks for informative video's.
this is incorrect. if you measured servo *force* instead of *torque*, then you have to correct for the arm length to get torque. this is not a "35kg" servo (those dont exist) - its a "35kg*cm" one, meaning that, if you measured it using what appears to be a 24mm arm, your results are
35kg:
6V - 43.92kg*cm
7.4V - 50.16kg*cm
8.4V - 53.93kg*cm
same goes for the other one. the metal arm you used even has a hole located at 1cm that you can use for measurement.
Can u test savox 1210 and 1230. I’ll send u them if u need
Yes, they're coming. I think there's the 1212 new one that we can't find.
RC Review never heard of 1212. But I’ll be looking out for 1230
Awesome channel thank you
So curious. Since the kg ones are measured at 1 cm not 1 in wouldn’t you need a different mounting place on the servo horn to correctly test it for its claims?
Of course not, he just needs to convert torque unit.
jx servo also has 60 and 70 kg servos. Would be interesting to see how much those are lying too
Typically, manufacturers will be off by the same percentage. So our guess is actuals will be 60% of claims, just like the 46kg
they claim 35 and 45 with more amps i think like 5.5 amps
I must say, I am very surprised and disappointed in the Jx servo. It is off by about half a mile. Which servo for the prize, would you recommend that actually puts out close to the stated KG numbers?
The Power HD KG20 is very good. The Reefs 555 is strong and honest too.
What is your favorite servo and has your choice changed due to your testing?
Reefs 555 has really stood out. Also the Holmes V3.
@@RCReviewChannel I believe my next purchase will be a reefs 444, 555 or raw 500.
WoooooW very nice
Great channel...
I want the truth!
Neither came close!! I'll stick with my Power HD 20kg and 25kg Servos...
Carmine ✈🚂🚙
It’s that new “common core” Liberal math. If you feel like your 50KG, then damn it, you’re 50KG! 🤣
New math says make up some specs and sell a ton!!!!!!!
Of course I see this after I buy a bunch of cheap servos...
The Power HD 25kg is actually worth the money 👍👍
@@CarminesRCTipsandTricks cool. That's the one I bought two of. Gotta be better than the stock SCX10.2 and Traxxas Slash servos anyway.
@@Mletchworth *MUCH* Better!! They just tested the Power HD 20kg Servo Here. Put out what it claimed. Surprised Francis with the results!!
Thumbs down for measuring Kg/cm in oz/in and forcing me to watch to the end...
Ok all this tests are "static" under dry labority conditions! What does a Servo you have used under hard crawler conditions till a year ? I run many of this China 20-25kg Servos and non survive more than 10 rides ,realy though rides! The only china Servo that all my "tortures" withstand was the JX 45 (grease main bearing before drive under water). Would be intresting if you put a Servo under "torture test" in your crawler. Which survive the longest time? Which Servo "you" use the most ? Servos are the most "tortured" expensive part that work in a crawler would nice two know which are the thoughest for the money!It would be nice to have a Servo that can be "serviced" with spare parts,we have more than enough waste on our planet.
Those 35kg servos can be had for $25 or less on eBay now ... they have more then enough power for my crawling needs and for $25? Shut up and take my money!
You are Mixing information, kg lbs...super confusing !!!!!
Wow a little disappointed in my favorite servo The JX 46Kg did not hold up to its clames.....poor lhem...second though por me for believing there B.S.
Yeah, sucks. Looks good and good price. Just wish it matched up.
@@RCReviewChannel Thank you for these tests.
I have these servos the JX and DSs. For the price you pay in USA for them they are barely worth it.
I buy them directly from Aliexpress (China ebay) for JX 46kg(but the 12V directly 3S) is $40 shipped and the DS35kg $19 shipped.
If i was living in USA i would pay more and get the good stuff like the Reefs and Holmes :(
The jx 46kg brushless is way better
man your angles are off, you can't measure torque that way. a lot of the force applied by the serbvo si not going vertically and you aren't measuring it. Scientific tests run in totally inaccurate way are extremely measleading to the ones who don't know.
All marketing wank my friends, all marketing wank. Numbers and picture graphs, ohh boy yes look, see! Must be good! Whomp whomp whomp whomp.... 💩🤑
Yeah let's measure metric claims, in stupid imperial and then splash the math conversion up for 10sec.
Learn to metric.
JX are rubbish .
