It would be awesome if you put links to the parts
I greatly appreciate your videos. I’ve watched this video multiple times back when I first started the hobby. Now that I have more knowledge on the Hobby I’m rewatching and wow. So much information thank you for documenting all of this. I’m trying to get my family into the hobby and your videos are amazingly helpful. Thank you!!
Used the exact same parts shown here but enjoyed full speed for about 1 - 2 minutes, after that it moves like a turtle for few more minutes. I'm using the esc on 9125 truck and it works great!
Im completely new to the RC world. I have this car coming in a few days and im going to do all the upgrades you did. Not for any other reason other than getting experience on changing things around to build my confidence.
Even if i mess it up then no huge cash lost.
Cant wait!
Adidas Lover enjoy the hobby. I’m currently waiting on my WPL B24
Love the FS radio!
I got 2 for 25$ off Craigslist and they run great. I need to figure out a cheap steering fix, or lack of steering. I don’t think this car worth putting that much money into but as long as your having fun and you like it, do it! Love the video! You did a good job!
hey!! So let me give you an update on this, all your obvious steering issues will never go away, I have tried everything so far. I even got the adjustable metal turnbuckles all around, and they are such awful quality that you will have even more slop than using the stock plastic links. It seems every youtuber on here other than me does vids on these in order to just BS you and sell parts through affiliate links. But let me tell you right now, no point in upgrading these at all. Just run as is. Only good upgrade is to get the 1/10 scale wheel hub conversion so you can run generic touring car wheels.
Thanks. I think just found out this servo also fits the 144001.
That's pretty quick
thanks my dude!
Please make a video showing how to fix the steering and crooked wheels. thanks!
Awesome!
Does that new esc that you mounted works with the original control?
Rcmodsquad did a video on streatching the tie rods. All you need is a heat gun and patience. Or purchase adjustable tie rods. This removes the slop in the front tires.
hey man!! thanks for watching. I eventually purchased a set of aluminum adjustable turn-buckles all around (including steering tie-rods) What can I say, it became even worse. First of all metal threaded into metal is a terrible idea, it requires a lot of threadlock to keep from turning out. Second, the ball-ends which the screwes are threaded into are terrible, they have more slop than the stock plastic. I am fully surprised that nobody on youtube has mentioned this, makes me think they are unaware and lying.
@@hybrid32494 bruh I feel the same way.. the metal ones are a total pain in the arse and were no improvement. I went back to the stock ones.
That is work. If you upgrade the esc with old remote
Thanks for the video. You changed all the parts more for reliability. I'm new to this. What contribute to the higher speed? The ESC?
If you want more speed you need brushless ESC and motor, more KV = more speed, less kv =more torque, more volts= more speed, KV= rotations per volt
Oh crumbs, was that 3s you tried?
Seroiusly 320A brushed? To way big. And its fit already. Btw can you tell me what esc brushles should i buy that already fit with the original place? I am about to upgrade to brushless
I have the 2 x A959 (Truggy version) upgraded to 'B' motor, then back down the 380 motor. I put the A979 wheels on it - much better! The stock steering is hopeless. Lots of toe out! Adding some adjustable tie rods to the steering allows adjustment to a bit of toe in... along with ball bearings most of the slop shown is removed and it steers quite well. I could hold full throttle with the 540. A 540 motor is way too big for this model - the 380 is lighter and far more suited to the size of the car and not so hard on the battery. They break a lot. I have big box of spares ready to go. Even if you upgrade everything they are still a cheap design made of cheap plastic which breaks easily. They are a fun car/buggy but you could have something better for the money+upgrades. Good article on the cheap RC / ESC upgrades - I have some old Tamiya Hornets that will work nicely with your upgrades - many thanks hybrid32494!
Can wltoys esc handle 390 dc motor without any overheat issues
Hey man do you possibly know the motor pinion gear pitch for the hosim q901-902- 903 ect? Thanks man.
i recently did this upgrade. Right now i think the low voltage cutoff is being triggered after only 2 mins of running. Didn't have problem with battery before. Set up is identical except for ESC i used the hobbywing 1060 brushed. Any help would be appreciated.
will this run with a 20A esc?? i just need the servo to get running and i have both the reciever and esc,and i dont wanna dish out the extra money for a new esc if it will work on the 20A
hi man where do you buy that ESC? can you put here de link?
thanks
You mentioned the parts that you upgraded, but could you put links to them please?
What a fast rc car!!! Can you tell me what kind of remote you were using?
hey buddy, thanks for watching. The remote is a flysky fsgt-3b. its terrific budger remote which you can use for upto 10 models. The receivers are only around 7 dollars each, it's never let me down. The remote and RX cost about 35 dollars brand new.
Sir hope you will fine.i did upgrade my wltoys a959b also with the same esc.but this esc becomes overheat within a min.incase if i use slow speed this esc works normal but if i use in high speed this esc becomes hot immediately and slows down the speed automatically.
I have 1 another same brandnew esc.but that esc only works in frwd direction and do not do reverse.do you know any solution about this esc problem
The wheelbase is too small for a fast car. Don’t expect to get a fast car out of a matchbox, I have it and it’s great for small spaces and just having fun.
Upgrade esc to traxxas xl-5 brushed esc, grab a servo that fits may have to shave servo mount a little and goolrc or similar transmitter and receiver. And power and speed alot more with factory motor and battery.
Alot more punch and speed.
Maybe you can help me out! I bought this esc and used it in my a959b as well as my 144001 and the problem I have is the esc cuts out and the battery is anywhere from 70 to 50 percent left. I let it sit for a minute or 2 and then it runs again. Have you had similair problems?
I also have that problem. Been running it on 1s Lipo. But I'm wondering if the letters "2 - 3s lipo" has something to do with it. Like maybe the 1s is not powerfull enough to run it properly(my last thought). If you find the answer before me, let me know :)
Birds like "wtf is that thing"
I said that too after flipping it for no reason, LOL. Thanks for watching!!!
😂😂 bird nearly breaking it's neck to see what it was, quality! Nice video man gave me a few pointers on what equipment to use and what issues I'm going to run into because I'm upgrading a friend's to brushless system, crazy fun in a small package!
Do you know the rating of the BDESC-S10E? It says 320A but that can't really be correct. Do you have any idea what amperage of ESC you need based on whatever battery size you're using?
hey buddy, I know, the 320A rating must be the Burst Amp rating and not the Continuous. Anyway, what matters is the amount of discharge (C) a lipo can deliver continuous and at a burst once in a while. I usually run no more than 30C in these cheap RCs. The stock lipos that come with these are rated at 20C continuous. In more high end 60-80A rated ESC you can safely run 50C packs. Chances are the tiny lipos made to fit these models won't ever be over 35C discharge anyway, unless you get some high end lipos.
@@hybrid32494 A higher C rating battery won't hurt the ESC though. It's just he RPM it generates that would harm the motor. I guess what you're saying is that motors on these small budget RC's won't need anything beyond 30C. Anything larger would not be utilized and a waste in the extra cost of the battery. Running 50C or even 100C battery does no harm.
Nice
hey, thanks!!, you have one too?
I have a979b, crazy car ... and very fast
Can i change just the steering servo??
It also works with the original remote control
Jermaine Saunders
That receiver works with the original Radio ...😮🤔
It doesn't.
@@luissimoes8106 no.
Can u drop a link to the servo
Great vid! Thought it would go a bit faster. Maybe a gear change? Enjoyed it...
hey dude!! thanks for watching, I could def have got more than 40, but you saw how going top speed was very tough. At least no glitching now. I need a way to tighten up the steering, its too sloppy.
I know what you mean. I have movement on all 4 corners so it makes going straight very difficult. Still fun to drive!
I also noticed that your right front tire is toed out quite significantly... My truck was the same way so I got the adjustable toe link and was able to set the toe straight on both sides
YEs, the front has so much wobble, the most I've ever seen on any rc car in my life. So you only got the adjustable turnbuckles? or did you also work on the actual Ackerman steering mechanism itself?
I got the front adjustable rods to make the tires straight and replaced the steering bell cranks with aluminum ones. I also got the aluminum bar to replace the flimsy top chassis bar above the drive shaft to strengthen it up some. Going to try and shim the A arms. Lots of slop there. Axles need some shims or something as well...
thanks for the advice, Im gonna try to rig up some home made turnbuckles soon.
i would recommend sticking a gyro on it for increased stability
hey buddy! thanks for watching. I am making an update video on this thing and it will be out soon. I have since converted to normal 1/10 scale wheels, and a brushless system, and yes, I'm putting in a new flysky gt5 remote and receiver with a gyro. good idea!!
@@hybrid32494 I'm happy to help bro, im the biggest fan of your vidsss
Nice video mann!! Where did u buy the truck??keep it up 👆. 😁😁
thanks dude!! I got this on eBay about a year ago so far, pretty much still dislike it. ITs quick, but the steering is still terrible even with a great new hobby grade servo. The steering geometry is just poor.
@@hybrid32494 you can change the turning shafts to increase the steering radius(geomatry)
by turning shafts which parts do you mean? the steering turnbuckles? IT seems like the tires don't have any more room to steer anyway. Next thing id like to try is to use 1/10 scale touring wheels after I figure out how to modify the small wheel hubs to run standard wheel hubs.
@@hybrid32494 hey bro. Use the 1/10 scale truck tires(not monster truck ones) because at the 🔙 side its bigger than the diameter of the front. You get me bro. I got that kind of rims and it works 😁😁
Were you ever able to modify it to be stable and controllable?
I did put in a hobby grade metal gear servo and receiver. But the control in terms of the steering was the same. IT just comes down to the steering slow and the tires, mostly. I am currently working on putting on 1/10 scale touring tires and a brushless system, that will be the real test.
Needs upgraded wheel bearings and adjustable front arms. The alignment stock is ass
I have the same car but the slower version and I think the wheels are so lose is because the inside side of the bearings are too big to fit well
Nice and easy mods. BUT why didn't you try with 3S? It would surely have reached 45 mph. Changing the esc is only useful if you plan on using higher voltage no?
hey buddy!! I eventually did upgrade this model to run a a full 5200KV 1/10 brushless system, needless to say it's insane now. Check out that video on here. I got the cheapest eBay system for like 28 bucks, pretty good.
@@hybrid32494 Just saw the upgrade, looks neat. However, I ordered Pirates 2 80A from banggod as it was very cheap : only 216$ for RTR. I'll add some serious 150A esc and switch motor then.
But I almost order this A797B by hoping I could upgrade it to make it as fast as you ;)
you could get these so cheap now anywhere, it's worth the money just for the fun. Even if you get the cheaper B version with the 380 motor instead of the 54- motor, it's still worth it. Good luck, you're gonna have a super quick RC with the one you got too!!!
I did the upgrade only problem I am having is the car is slowing down before the battery is dead? It runs great just after 2 to 3 minutes of running it slows down as if the battery is dead?
hey man, which battery are you running in this? It sounds like your lipo cut-off in getting triggered. Usually the low voltage lipo cut-off will reduce power in the way you are describing it. Try a different battery. let me know.
I have the same RC TRUCK A979B , i want to know whats the right size servo that fits like a glove because a lot of people have gotten wrong ones or jimmy rigged one
Got same problem too..bought BL combo but the servo comes with it doesn't fit..to big for the car..

Hola muy buenos videos. Podrías apoyarme como enlazar un control de jjrc q39 a un receptor, FYRX02 JJRC FY01/02/03/04/05 Q39 es uno pequeñito transparente. lo que sucede es que no es igual al original receptor. Dice que es compatible, aún no lo intento hacer ya que me costo mucho trabajo conseguirlo y no quisiera dañarlo. Espero quieras ayudarme gracias.
Change your tyre & rim & you will get straight...top speed for standard part around 50-52kmh...
Can u use a dumbo rc receiver and controller?for the servo and esc
hey buddy Yes, you could! You could use any radio and receiver, as long as they are made to work together and can be binded (linked).
My motor is gliths and i buy new motor i want to change it but i don no how to change it? Can you make video new motor plsss
Used the exact same electronic parts u did on my 979b and the servo worked fine but when I connected the 540 motor it went up in smoke 😐 My thought was the esc was faulty..... any reply would be appreciated 😊
Hello, as it turns out I am currently editing a video about this same ESC that also went up in smoke after about 5 runs. AHAHAH. It must be the ESC. Mine got so hot after a ten second run that the negative terminal became unsoldered. I have since ordered a new 540 brushless system, (cheapest I could find, will be installing that soon.)
Thanx man!! Ya mine went up in smoke instantly didn't even turn a wheel. It was like a little light show 4 a second coming from the motor. Interested in your brushless set up when it comes out. Subscribed!!!👊👍
hey buddy, thanks for the sub. Still waiting on the brushless setup in the mail, for now I will publish another follow up video of this after the ESC meltdown where I attempted to fix it.
@@hybrid32494 nice, can't wait to see it!!
@@hybrid32494 my stock motor burn also...then change to 540kv 13T on stock esc got decent runt the motor melted down. No extra fan on it just heat sink;) now got BL system...
Why this rc can' t use order battery??
Good day Sir, how’s your upgraded electronics now? Are they still ok?
hey buddy! hw are you. Yes, the electronics are fine. I have since converted to a full brushless system, but the overall drivability is terrible, I highly recommend you stick to stock systems as much as you can on these models.
@@hybrid32494 Oh ok buddy, atm I'm just planning to change the brushed ESC and the servo same as yours. No plans yet for BL system.
Will that new esc work with the stock controller ?
hey buddy! the answer is no. The old electronics are a 2-in-1 combination receiver and ESC. Modern hobby grade electronics use separate receivers, ESCs and radio which are bound to the receiver.
Do you need to change remote if you change your servo?
hey buddy! The standard servo that is included in all WL toys models cannot be used with any other motor system. When you get a hobby grade Motor system and radio you must also upgrade the servo. The wiring of the standard servo is not compatible with hobby grade receivers.
Do you know another same size as stock servo with 3 wires, but with a bit more power than 9 grams?
YES< here is a servo for you, I have upgraded to this exact one recently myself. It's very powerful. amzn.to/3cIbBAh
Thanks
Hello...i just need an advice about the stock esc of wltoys a979b how to take care of it.?max run time?
hello, you don't need to do any special service or maintenance to the stock esc in these. You just run the original equipment and battery and it will be fine. Run time will vary, about 8-15 min. When your battery is low the ESC will just cut power.
@@hybrid32494 i just run it about 6mins but its already overheating i cannot touch it..it is normal?
maybe you need to slow it down a little. The motors will always get warm, mine does not get too hot though. Depends. Generally the battery will be depleted before you can over heat it though. Let me know. Just take it a little easy and see how it responds.
Hello! I have an unrelated question to this vehicle. It’s relating to the wltoys a959b model. I am trying to replace the front shock tower but one of the screws is completely stripped/ has no ability to turn using a philips head. I’ve tried using the rubber band technique, but still no luck. What do you recommend I do?
hey bro! I just looked at my own model to see how to help you out. You could push the screw out from the back of the shock tower. I know, those screws strip almost instantly inside the plastic itself. Anyway, take a very small hex driver and just push from the back while also unscrewing the front. IT should come out easy. Let me know if that works for you.
hybrid32494 hello! I think I’m referring to the bottom screws which are philips. Not the top 2 holding the shocks which are hex. One of the bottom screws ( there are 4 of them), is stripped. I can’t access the other side to remove the screw at all as there is nothing. How can I send you a picture ?
ok, I see what you mean. You might have to just insert a flathead screwdriver where the two pieces fit and then pry it apart. Worst case scenario you will just upgrade to an aluminum part. Or you can just use a larger screw next time, it will still be fine. Those WlToys parts are just not meant to be disassembled multiple times, you know. Those tiny screws constantly get stuck in the plastic.
Bro got the goolrc s2838 4500kv BL combo,seems the servo comes with it doesn't fit. Can you pass me the link you used on your rig? Got also a flysky fs-gt3c for the BL set-up I got..thanks!
hey man, congrats on the brushless system, you're gonna love it. You can use any small scale micro servo. I just happen to have the TOWERPRO MG950S around. Don't worry too much about the servo, I would honestly get a different one in your case. The one I used I would not use again (it has a very small amount of free play at all times). All these micro servos are cheap nowadays anyway.
@@hybrid32494 emax es3004 will it be good on my BL set up? The one comes with the combo seems bigger to fit..
do you have a link to the combo you baught, I want to see the servo you're talking about. It should be fine, you can always mod the chassis a little and just use a zip tie and hot glue if the mounting is not the best. Hot glue does a good enough job even with this.
@@hybrid32494 yeah I already mod a bit..drill some small holes and add zip tie but the servo to strong it twist the chassis itself. I will make some vid and show you..here's the link...www.lazada.com.ph/-i276263391-s410753619.html?urlFlag=true&mp=1&spm=a2o4l.order_details.details_image.1
@@hybrid32494 here's my video...m.th-cam.com/video/4gK9ij17QIY/w-d-xo.html
Hello. . I have improved the parts of the car, I have put the metal parts. But now the servo has no strength to turn the wheels. 1- If I put the servo that you have put in, will the problem be solved? 2- can I put only the servo? or do I have to also put ESC 3- will it work for me with the station that the car brought? I'm writing to you from Spain, forgive my writing, I speak very bad English. greetings and thanks, you are a crack
Any different max speed compare with the esc standard?
hey buddy! Good question. The answer is no, It performed the same. These systems are generally limited by the discharge rating of the battery more than they are by the ESC or motor. Meaning the Lipo cannot deliver such a high discharge at one time. A higher "C" rated lipo would be more effective for that.
@@hybrid32494 Hello, I've got a question...
Are you from Russia?
That hobby grade ESC is junk I had two of those and both of them popped while lifting the car off the ground to make sure the tires go forward it said it was compatible with a 12 turn motor but apparently not I wonder what the turn of that WL toys motor is considering it goes as fast as my 3S slash
I’m putting this comment before u take it out for a test run n my prediction is when this thing hits the higher speeds it’s gonna be way hard to control I think it will start to sway side to side, well we will see what happens
That’s too funny brotha u said exactly what I wrote in my earlier comment it’s uncontrollable at high speeds, I figured that would happen as it’s so hard to get these lil rigs under control, but wow I’m surprised it did as well as it did 40mph is great for that thing
yes dude, 40 MPH, not bad. But the steering, crap. The prob is the steering geometry I think, it's just super sloppy. Not like the terrific tamiya lunch box, you'll see in the upcoming video, I gave you a good shout out in it.
hybrid32494 that’s awesome bro thanks n I’ll be looking for the lunchbox vid 👍😎
Its not a full metal servo seen this video just bought one smashed the plastic gears first little bump. The old 5 pin servo is still going in my other brushed one...
How many turns has the stock motor please?
Should be something in the 20-12T Region...
Can you upgrade just the ESC?
hey buddy! thanks for watching. Unfortunately you cannot upgrade only the ESC in any WL toys model. The reason is they all use a combination 2 in 1 ESC and Receiver system. IF you change the ESC, you will also need a new radio system and servo.
hybrid32494 do you think I could just swap a 3s battery? I know I’d run hot
how to connect servo
hey buddy, you need to use the stock servo horn. To modify a servo you need to run hobby grade electronics also, this model comes with a 5wire servo, not the same as standard hobby grade equipment.
Put brushless motor and see speed
I need the link of servo, please!!
hey buddy! Here is a link for these servos for you.amzn.to/3fyMfHd
@@hybrid32494 thanks
The advertised 320A on that ESC... LMAO! Why do the Chinese always lie about specs? Reminds me of those "8000mah" 18650's... 320A at 8.4v (2S peak charge) is about 2700 watts... you aren't putting 2700 watts through any those wires... unless you're making a (very short lived) light bulb.
I built a fast old school grasshopper and almost impossible to control, that not bat, 39 mph
hey bro! I still have this thing, but have given up on speed runs, it's not controllable at all, and not worth the upgraded electronics In m opinion (to me at least). Anyway, I also have a tamiya lunch box and it got over 30 MPH on a tiny 3S with a 15T motor, not bad either, right.
I have a wlt 959b if you dont have one I recommend one mine does over 55 mph I'm soon to be getting new motor and more upgrades
hybrid32494 dynamite has motors with the esc’s built in. Will cost more though.
Tmaxx Toni could get 50 out of that lol
whats up!! T-maxx Tony had a Picnic at the beach today before driving the Primal MT.
Battery too small, difficult to upgrade, very little space for battery, esc blower also difficult to install.
those micro servos are junk. i broke 2 of them in an hour. lucky they came in a 4 pack from ebay for 10$ the esc works fine though. oh and the micro servos have a smaller spline so factory steering knuckle does NOT fit
