Great comparison, I have 3 jx Hv 7132 black and silver case servos I run in ebuggy and nitro, for throttle and steering, love them!
Thx agian for your input, I'm new to the rc world...
bill you the man. i didn't realize it was you on here too until i just came to revisit this video after receiving my 5821 jx servo. but you helped me a lot deciding on what first truck to get for racing on the rcgroups forum. just wanted to tell you thanks for your post about the 4x4 sct's scores I ended up picking up a used team associated prosc 4x4 thanks to you and im upgrading it to be my first racer. got a JX 5821 server today thanks to this video too lol
glad I could help!
Congrats on the new truck and best of luck with the new servo too!
@@billdelong thanks, so far so good. I started with a helion avenge sc10 i bought on amazon for $200. great truck for the money but i ended up breaking the front skid plate within 3 days and it's is a mounting point for the steering turnbuckles and now it wont steer straight. can't find any parts for it hardly so HobbyTown ended up giving me a full refund since Helion went under and I ended up getting the ProSC 4x4 used as per your recommendation on the RCGroups forum page about the best SCT's to start with. Ironic that I found this video after searching for a decent servo upgrade for it and realized it was you as well so I had to make sure to say thanks lol! So far I like both the truck and the Servo and will probably be buying a faster JX one when I get better on a track. I've got a bunch of upgrades coming for the ProSC which the sway bars were impossible to find unless you search for Thunder Tiger sway bars on eBay and order them from Germany. It should be a force to be reckoned with when fully upgraded though.

cool deal, some info here worth a read in selecting your next servo:
www.rctech.net/forum/showpost.php?p=15403144&postcount=6
I'm running a coreless jx 32 kg. It is super smooth, quite, and plenty torquey for my SCX102. Metal gears, aluminum body, and waterproof for $62 U.S. definitely recommend.
Just got back from testing my new JX 5821LV servo compared to the stock xp digital ds1903 my prosc 4x4 came with it's night and day. the seller did botch the description I thought i was getting a hell of a deal on a coreless 0.11s4.8v - 0.09s 6v (new to the hobby) but in reality it is a 0.18s 4.8v - 0.16s 6v cored 2bb. I guess they put the description on from the more expensive JX 5830HV on the ad but in reality it's a JX 5821LV. Even still it's lightyears better than the DS1903 specs are 0.15s 6v @ 3.8kg - 50oz. I think I gained like 200oz or 16kg of torque compared to the stock. I'm going to try racing with it and see how it does. I'm going to also see if they will send me the 5830 that I thought I was getting.
excellent video, thank you sir.
which one is better the JX servos or the power HD servos ?
Hey Bill, how did the testing go in your e-truggy of the JX brushless servo? Is it strong enough for racing?
it's an absolute dream, by far the best servo I currently own, highly recommended for 1/8 truggies!
Sounds good. Thanks!
I’m thinking to get the Jx 7346 at 46kg..😀..I have heavy wheels on my MT410..
Hi
Can you give code for rotate 90 degrees?
I have a project to rotate servo to 90 degrees and back to 0 degree with rfid and ir obstacle sensor switch.
Hey Bill, looking to get one for my Arrma Kraton. Which servo would you suggest and are they water proof? I'm also looking for a decent not overpriced waterproof esc.. Thx for informative video..
I would buy this one for myself if I was gonna buy one today:

If performance wasn't important, then I might consider this one even though it's kinda slow:

Why not the JX BLS-HV7032MG, on the jx website, all their brushless servos are listed as waterproof. Is it not? Have you tested? It's stronger, faster, and similiarly priced as the Power HD you recommend above. Thanks for your kind reply.
Hey Bill, I know it’s been a while but what’s your thoughts on JX after all this time? Thinking about 4 of the JX BLS-HV7032M on an airplane wings since they are as fast savox and I’ll be using 8.4v. Can you say something about the play on the gears when power is on and servo resting, comparing with savox? Thank you
still running the 7032 in one of my race cars, the gears tend to wear out after a year of use and start to get slop at that point... I have found the EcoPower gears to be a direct fit replacement, no slop in gears with a fresh set of gears installed:
www.rctech.net/forum/showpost.php?p=15403144&postcount=6
@@billdelong do the 7032 and 7232 use the same gears?
@@stokedGSXR not sure, it's been many years since I've owned these servos and don't have access to compare parts anymore, good luck!
@@billdelong no worries! I'll get a set of gears and see jf they work and update here in the next little while. Can't hurt to try!
I'm interested in knowing what servo you like now! I saw the falling out with agf but haven't seen many of your posts recently on the topic! You're always a good read!
@@stokedGSXR Thanks for the kind thoughts..
I am still running Nitro Pro CT2 servo in my eTruggy, that's a solid servo which is rebranded AGF that is highly modified and corrected all the design flaws from AGF.
In my eBuggy I'm running an SRT9032 and love that servo too... going forward I'll probably stick with SRT servos.
Hey bill, I look at ur post in rctech. U said that ur jx servo already striped its gear. And change the gear with other cheap jx servo. which servo did u use to change the gear?
I don't remember which one unfortunately, it was just the thin gear in the center, if you stripped the main spline, then this trick won't work :(
@@billdelong my car got quite a significant slop at the steering. And i found it from the servo. Is it normal for servo to have some slop?
No, when slop starts to form, it means that the gears are wearing out, just a matter of time before they strip.
@@billdelong seems like a bad news for me
It wouldn't hurt to clean all the gears and apply fresh grease, then flip them around 180° to use the good side, that should double the life of your gears ;)
Thx Bill, gonna order the first one... Can you also suggest a waterproof esc... Thx in advance!
I haven't tested their ESC's but I've heard good things on the forums,
and I love their motors, if I was going to buy a waterproof ESC today,
I'd get a GoolRc, depending on your motor, I'd go with either the 120A
or 150A version:
www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR0.TRC0.H0.Xgoolrc+waterproof+esc.TRS0&_nkw=goolrc+waterproof+esc&_sacat=0
after going through their selection, it doesn't appear that GoolRC has
any 150A waterproof ESC's after all... in that case I'd probably go with
HobbyWing just to play it safe
That jx servo looks bad ass! 50 bucks! I paid 89 for savox 1273tg because I wanted fast speed, at 7.4 it is .65 which is lightning fast! But, $50 for that speed and power? Is a steal!
I agree, it's a good deal, only problem I have is finding replacement gear sets... the steel tends to wear out after a year or so making these servos somewhat disposable when the gears strip out eventually :(
Check out "asiatees.com". There you can find spares for Jx servos
What about backclash? Thanks!
I got a question at 3m 12sec that sound, what is that? I install mines today and noticed it was doing that.
every savox I've owned has done that "chatter" sound, very annoying and very much normal for savox.
Savox is still faster... the only reason your are hearing the savox make noise...It's because it's always trying to find it's center point..(It's not stressing)...
Savox is considerably louder under the same load and also pulls more power under the same load and also runs hotter temps under the same load.
Savox may be loud and power hungry but no one can question their power out put or durability
The Savox is faster, because the Savox has a speed of 0.8 seconds with 6V. The JX has a speed of 0.8 seconds at 7.4V. JX is a HV servo. It may therefore have a speed equal to or even higher than 1258. The important thing is to supply the appropriate voltage .
How did this servo perform in real life situation?
Just as good as Savox, however the gears lasted about a year in my 1/8 cars and needed to be replaced, I found that EcoPower gears from AMain are a direct fit as they are rebranded from JX.
I just got a jx coreless and it’s making a slight clicking sound when changing directions. Is this normal?
Brand new out of the box or after a hard crash then the clicking sound started?
Are you sure it's not the digital oscillation?
Bill DeLong brand spankey new. And not sure what you mean by that
@@jmurr357 post a link to a recorded video, happy to listen and see if it sounds strange
I use a jx 4409mg
Have tested it? How was it on the track compare to savox?
I run the JX brushless servos exclusively in my 1/8 buggy and truggy, great servos that perform very well, highly recommend them!
@@billdelong Are you satisfied still ?
@@HeliModTRC your timing is perfect, if you asked me last week I would've said yes, but this past weekend I ran into some glitching with one of my JX servos that I need to investigate. Problems went away went I swapped out the 3 year old servo, to be fair I had shortened the servo wire and didn't do as good of a job at wiring my replacement connector as I should have so it's possible that my issue was self inflicted... I plan to replace the connector soon to see if my glitching goes away.
@@billdelong Thank you :) . Please tell me what happened when you changed the connector. I will JX Servo for Helicopter. But your experience is important.
Pretty sure I made the length of the servo wire too short, there is some chassis flex in my car and I think the servo wire is getting pulled from the Rx after a hard crash, etc... since you will be using these for aircraft use and no impacts on the equipment, I think you will be very satisfied with the results. I would make it a point to periodically inspect your servos for any slop starting to form, I have had to replace the gear sets when running these servos in 1/8 cars, the gears last considerably longer in my 1/10 cars, no idea how they will wear in a helicopter.
Gear sets from EcoPower WP120T at AMain are compatible: www.amainhobbies.com/ecopower-120t-metal-servo-gear-set-ecp-3099/p755536
Hi
I am debating whether this servo can be trusted for a 92-inch 3D plane??
I do not have experience with planes that large, I would refer to the manual of your plane and see what specs they recommend for servo selection, good luck!
@@billdelong first thing thank you.
Perhaps I did not formulate my question properly,
I did not mean whether this servo (jx7032) fit my airplane or not.
I was going to ask if it is reliable enough to use it on a expensive plane ....?
@@3D-RC I feel the servo is reliable, however just be sure the stated specs for the torque requirements are satisfied for your plane... I would also inspect the servo horn for any slop in the gears... once you detect slop, then that is a good indicator that the gears are worn and will be at risk of stripping.
hi.
i use the xj brushless in edge 540 pilot rc 92" on all surfaces for 45-50 flights with 2 2s 3000mah lipo
like them very much perform very well
very nice servo
economical in power
after 10-12 flights have left about 75% in the batteries
think to put smaller batteries
Is the brushless silent?
compared to the Savox, yes however you can still hear the JX under heavy load, though it's no where near as loud as Savox
@@billdelong Thank you very much for the reply! I'll go for the brushless in that case!
Sad to say Savox is losing the game already..there r better and cheaper ones now like JX, CYS..Xpert in another high end servo..
Savox is losing the game? says who? they are sponsoring world champions now.. If anything they have cemented their place in the hobby with impecable reputation and value.
why your sevos sound like a truck... 😂😂😂😂😂
better put some lube inside man, it's worth it then let your servos die ....
More than half the price here
and Savox has it...easy
Why not use a fish scale instead of weights? It will tell you exactly how many pounds/kilos each servo is good for in only a second, and they cost like 10 bucks.
