Thank you for this video! I spent hours looking for a good servo for my 12428, bought one servo of other size and used it with 3d printed bracket until it died 2 weeks later, then used original servo with soldered controller from that dead servo. After finding your video I've purchased JX PDI-2506MG and I am very satisfied. Perfect fit, budget friendly and very decent.
I'm using the SURPASS S0025M, it's also a direct fit without any modifications and sofar does a very nice job. The big pro for me was, that it was directly available from amazon for a good price
There's an official upgrade metal geared servo from wltoys , don't use it, it's not much better than the stock one. Btw: You can easily use the 3wire servos on the OG wltoys esc. Just remove the pcb from the 3wire servo. The 5 signals that go to the wltoys "brainbox" consist of 2 for motor and 3 for the potentiometer. Not really proprietary (connector is a JST 1mm or 1.25mm pin pitch and available at mouser, digikey and the like) but for cost savings sake I guess. Thanks for the video.
I had a problem with the jx servo. I had run it one time and worked perfectly, but the moment I went on the 2nd run it stopped turning and started to make a high pitched scream. Do you know the cause of this? Plz respond. Thank you
I mean the original seems much faster with no load but when it doesn’t have the power to get the full throw to use the full turn radius, then that speed is pointless. The JX servo is so much more powerful that when the servo is loaded down with all the links, joints, steering components, wheels, tires, ground friction, etc it still functions great and will give the full throw of the servo. So essentially under no load the stock servo is noticeably faster but that speed does not translate to usable speed when in use.
Hi. Did You made weight check how all metal upgrades increased weight of car? does it effect it's performance? Btw I very like these all your movies :-) in many cases I found answers to my questions what I had and wasn't forced to check by myself:-)
klaszczbass - Weighs 4.3lbs or just under 2Kg right now without a battery and yes I can feel a noticeable weight difference since I’ve added all the upgrades. Feel like it handles not too different but you can definitely tell it weighs more while it runs, feels a little less bouncy but that also has to do with oil filled shocks on all four corners.
Nice video! Subbed. Why do you use a 17t pinion? wouldn't that decrease the top speed? Also, do you know if the servo in this video and shock tower you used on the front for the standing shocks would fit on the fy03? thank you
Joshua Mei - This car came originally with a 17t pinion I just upgraded to an Axial 17t pinion because I kept destroying the “upgraded” metal ones from China and the axial one seemed to hold up better, the 12428 doesn’t have an adjustable motor mount so pretty much stuck with a 17t pinion unless I want to make a customized adjustable motor mount which seems unnecessary seeing as I’m happy with the low end and top end speed of my setup. No idea if this shock tower mod would fit on the fy03 never owned one, know they are built similar but dunno if it’s similar enough to create the same shock tower using the same a959 shock tower. As for the servo the FY-03 I believe uses a slightly smaller servo than the 12428 but I know they make a 3 wire servo for the feyue FY-03 and that is the FY-S3 servo. Pretty sure it will be a direct fit but I can’t say for sure, and dunno if it’s got any more power than the stock fy-03 servo but it will at least allow you to convert to 3 wire to upgrade the other electronics. That servo goes for like $8 on AliExpress and the shock towers go for pretty cheap too so you could always just order a set and test fit it, even if it doesn’t fit you’d only be out like $5 I think, if I’m remembering correctly.
Madness Destroyer - well the motor mount has no adjustability so you can only run a 17t pinion unless you modify the motor mount to be adjustable. Even then the motor KV rating and battery you use will play a part in how much speed you get. My 3200KV on 3s with the 17t pinion goes faster than I need so ideally I’d like to drop to a 15t but I don’t feel like modifying my motor mount so I deal with being a little overpowered. I could probably just drop to 2s as well.
Madness Destroyer - Yea you can find metal upgrades but I don’t know if they do different sizes. If you can find a different size then you should be able to change the gearing just need to find the right spur and pinion sizes that work together and end up with the right gear mesh with the stock motor positioning. But at that point I think it would be easier to just slot out the holes on the motor mount and make the motor positioning adjustable so you can run different size pinion gears and move the motor to get the right mesh. I’d order a separate motor mount just in case that doesn’t hold the motor well enough though so if it’s moving around too much and don’t keep the right mesh you can just go back to stock with the 17t.
I have trouble finding the correct arm for these smaller servos. The spline shaft size is different between the 1/12 and 1/10 size servos, but believe they can both be 25T.
Are there multiple revisions of the 12428? My servo is mounted 90degree rotated to yours (servo horn along the steering axis instead of yours that is along the forward/backward axis ) and the servo saver mechanism is completely different
Kinda got a Frankenstein 12428. A lot of the steering components have been customized and even found a way to attach the bellcrank steering off of a 1:10 scale Axial Yeti to it, but yea I rotated the servo myself so that my custom steering would fit right. Got more videos on this car including a video on my custom steering setup. Links should be in the description to all my 12428 videos.
Do you have the Feyue fy03 or something like that? I know that car looks similar to the 12428 but I know it has different internals and a slightly smaller servo. On my WL Toys 12428 it was a direct fit to the stock servo bracket with no modification needed.
I mean the connectors are completely different and I don’t see why they would make 5 wires if it would run on 3, I figure the proprietary design requires all wires for the servo to run. Either way the JX servo is not too expensive and a vast improvement over the underpowered stock servo so if you are replacing the esc and receiver anyways might as well include an upgraded servo while you’re at it.
So, if the original server has a 5 pin connection, it should be possible to put on a 3 pin connector and not use the 2 unnecessary wires? Or am I wrong here? Just starting in this hobby. Beside the point, that you would want a stronger servo anyhow.
Link is in the description, but it’s just a little aluminum servo horn but if I remember correctly it’s still a little too long so I had to cut off the top hole with a dremel tool to make it fit.
@@kamulot - in the description listed under “other upgrades” it’s like the fourth item listed. And yes of AliExpress. Sorry I would just link you in this comment but my device won’t let me highlight the link to copy it for some reason.

Hi, can you please tell me how much is the Stall Torque?
@Myn Donos I will convert it to a five wire
Nice review & testing set. You pointed me the direction. Thank you!
Great video helped a lot
I have a Corona (not vírus 😂) DS339HV, it fits the original servo support and works like a charm.
They say 5.1Kg and 0.13s.

Thanks for the video very interesting. How fast the JX servo PDI-2506MG is in comparison to the original one ?

If it wanted my car to go as fast as possible but still be “safe” what would be best upgrade pinion

K Yammo what about the center gear the 62t pinion is that upgradable

hello, does any 25T servo arm fit the stock servo?
I have trouble finding the correct arm for these smaller servos. The spline shaft size is different between the 1/12 and 1/10 size servos, but believe they can both be 25T.
Thx for the Video, Did I Need a new ESC for the Servo? Because of the 3 PIN Plug?
Yea you gotta swap out the esc then you need a new receiver and transmitter, possibly a new motor to go with the esc if you go brushless.
No , actually you can open the servo and switch the control boards with the wiring , making the new 3 wire servo a 5 wire.
Are there multiple revisions of the 12428? My servo is mounted 90degree rotated to yours (servo horn along the steering axis instead of yours that is along the forward/backward axis ) and the servo saver mechanism is completely different

@@AszBall Oh I see, that makes sense. Looks certainly nice
How did you fix the JX PDI-2506MG? I bought one but its wider and dont fit the original bracket
Do you have the Feyue fy03 or something like that? I know that car looks similar to the 12428 but I know it has different internals and a slightly smaller servo. On my WL Toys 12428 it was a direct fit to the stock servo bracket with no modification needed.
did you measure what actually happens on the 5pins vs the 3? maybe you can just disconnect 2 and run it on 3?
I mean the connectors are completely different and I don’t see why they would make 5 wires if it would run on 3, I figure the proprietary design requires all wires for the servo to run. Either way the JX servo is not too expensive and a vast improvement over the underpowered stock servo so if you are replacing the esc and receiver anyways might as well include an upgraded servo while you’re at it.
So I have a pretty stock Wltoys 12428 and I was wondering how did you turn off that safety thing where if you do a burnout it shuts it off?
Well I have completely new electronics so the new ESC means I don’t have the same limitations.
MIne (also stock) doesn't do that! I drive mine on 2S and 3S and never had this issue
hi i hop eyou can help. i broke the original servo bracket that attached to the chassis. doyou know where can i buy?
So, if the original server has a 5 pin connection, it should be possible to put on a 3 pin connector and not use the 2 unnecessary wires?
Or am I wrong here? Just starting in this hobby.
Beside the point, that you would want a stronger servo anyhow.
I would assume that would not work but I really don’t know...
@@AszBall I will try, while wating for a new server, when my brushless motor/esc comes in
I'll let you know
Hello, witch aluminium horn do you use with the JX PDI-2506MG
Link is in the description, but it’s just a little aluminum servo horn but if I remember correctly it’s still a little too long so I had to cut off the top hole with a dremel tool to make it fit.
@@AszBall ok but i dont find the link sorry. In aliexpress ?

Hi bro.. Waterproof or not? Thank you
Semut Kecil - not sure but I’m sure if you look up the servo the item description will tell you.
hey bro can i use it on stock 12428?
It’s a 3 wire servo and the stock esc won’t take that so no you need to replace a few of the electronic components.
@@AszBall thanks man
