- Hi RC Enthusiasts
Welcome to my channel and thank you for taking the time to view this video.
I've been following all those participants to the @poorboysrc speed challenge. I was have been watching in envy at the speeds that everyone have achieved. But there has been a caveat...the expenditure of the upgrades.
So that has gotten me thinking...can one improve the running of the RC car on a very strict budget of less than £5.00. In particular the power of the very item that drives the RC car, the motor.
So, I've raided my spare boxes and found a Mabuchi RS 540SH motor that is currently distributed with most Tamiya kits as standard. Can this humble motor be accessed, modified and made to perform better?

That was very interesting and educational for me. I have known the Mabuchi motors for the last millennium 😀. At that time they were still made in Japan. Nice video John. Best wishes from Switzerland, Thomas. 👍👍
Hi Thomas, thank you for watching and leaving me a nice comment. Yeah, I’m going through a thrifty time 😊😉😊wanted to see if the humble 540 could be made better, without spending too much money. Best wishes to you and the family 😉😊
Thays a cool idea John its fun to open things up any see what you and do ro improve it
Great video John Very interesting idea.. I'm cheap to so love the idea.. Very informative.. Side note I got stickers today should get vid out on that by the weekend brother.. Have a great day..
Hi Paul, thank you for watching and leaving me a very nice comment. Glad I’m not the only one who is thrifty 🖐️😎😊, so glad the sticker arrived safely, alway nice to have a friend. Best wishes to you and the family 😊😉😊
Back when I raced in the early 90's, our beginner class was called production where everyone had to use the same battery mah, motor, and gear ratio. The motor was a Kyosho Lemans Stock 05 which is basically their version of a Mabuchi 540. One day one of the guys who wasnt very good all of a sudden had the fastest car running 4.90's on the high line of the track( indoor oval) and 4.80's on the regular racing line when the fastest times were 4.95 on the regular line. The next class up which was stock were running 4.80's with the fastest being 4.79. A protest was called and track officials took apart the motor and discovered an armature from a modified motor in place of the regular armature and special lubricant for the bushings. He left the bushings in so if anyone looked at the motor from the outside, it'll still look like a regular 540 but he didn't think about if anyone wanted to see the inside though. Cost him a lifetime ban from the track
Hi, thank you for watching and leaving me a really nice comment. Such a interesting story 👍😎😉Best wishes 😎😉😊
Great video, I like the way you thoroughly explained everything.
Hi and thank you for watching and leaving me a very kind comment. I’m tracking the TT-02/TT-01 challenge with interest. Best wishes 😉😊😉
Interesting John! Haven’t really thought about doing any modifications to a standard silver can. But this is cool to see!!
Hi Freddy, thank you for watching and leaving me a nice comment. Best wishes 😊😉😊
Very good information, this dynamo has good torque. Thank you for sharing.

This is a really interesting and cool test. 👍👍👍
Hi and thank you for watching and leaving me a nice comment. Best wishes 😉😊😉
Hi John, I didn't think about upgrading a motor before, especially a 540 brushed motor. Thanks for the scientific experiment, pretty sure the Mr 540 didn't mind being a test subject 🤣🤣🤣. Take care and best wishes to you and your family 💯
Hi Al, thank you for watching, really appreciate your kind words. Yeah, unfortunately a 540 was harmed in the making of this video 😊😉😊but needs must and I needed to know if I could make a 540 motor better, it would have worked, if Mabuchi didn’t use bespoke bushings 🤩👍🤦🏻♂️best wishes to you and the family. (I’m hoping my stickers to you will be delivered soon, as I posted them at the same time as Paul’s (REIT Place RC) his have arrived, so hoping yours will soon too 😎😉😊
great video and information on the motor
Hi Duke, thank you again my friend for watching and leaving me a comment. Best wishes 😉😊
Hiya John. Oh well that was interesting to watch even though the answer ended up being no. I never knew that those motors didn't have bearings so I have learnt something. I wonder how much difference it would have made if you could have got bearings to fit? Anyway thanks for trying this so we don't have to! Cheers mate, best wishes 😁
Hi Pete, Hi, thank you for watching and leaving me a wonderful comment. Yeah, I was planning to do a speed comparison between motor with and without bearings, part of my upgrades on a strict budget idea, but…as the bearing are not standardised,that’s scuppered that idea 😂🤦🏻♂️😂. I’ll have to think of something else 🤔Best wishes to you and the family 😊😉😊
Very nice build video 😊👍💯
Hi Max, thank you my friend for watching and leaving me a comment. Best wishes 😉😊
Well that was an interesting and entertaining video, John! Too bad you couldn't get bearings to match the size of the bushings! I think Mabuchi did this on purpose with bespoke sizes! All the best, take care!
Hi Mark, thank you for watching and leaving me a very nice comment, as you usually do 😊😉. Yeah, I’ve got my thrifty head on ….trying to make something better, on a very tight budget 😉😊you know what it is…I’ve found the local Aldi store, now I hooked in even more, to being a tight wad 😎😉😊🤣best wishes to you all 😉
@@JF-RC I know how it is buddy, me being an OAP without a proper pension! We all need to be thrifty in these difficult times, great to see a video about trying to save money in the RC hobby!!!
@@MarkBryanRC no way! OAP ! You don’t look much more than 65 ! 🤭🤣😂🤭only joshing! 🤭😂🤭you look very well on video, easily get away with ……best wishes to you all 😊😉😊
@@JF-RC It's all the make up I use for the videos, John!!! Takes years off! 🤣🤣😜😜👍👍
A very interesting segment John! I've wondered this same topic before a few times in the past with some brushed motors I had laying around. I never did anything to find out so I commend you on your inquisitive nature and actually getting it done! I do think your suspicions are correct though. If we could find an adequate bearing that fit, I bet your hunch on this theory would be correct! I would think having less friction would help the motor attain slightly more performance than a brass bushing. I truly thank you though for sharing with us what goes through that Brilliant mind of yours! It was a truly fun and educational watch! WoW! I just used ; "fun" and "educational" in the same sentence...
I really must be growing up finally!🤣😂Go out and find a great replacement for that sacrificial Lamb of a motor! hopefully its got bearings on the ends of it!😉I bid you and yours a wonderful evening my friend! God Bless!
Hi Robby, thank you for such a great comment and very kind words of appreciation. There’s always a lot going on inside my head and ever since a small boy, I’ve always had that inquisitive mind of how things work, can they be easily fixed and made to be better or improved, even if it’s only slightly. If only Mabuchi didn’t use bespoke bushings, I wanted to do a segment of 540 against 540 with bearings in a head to head. Never mind, I’ll have to think of something else 🖐️😎🖐️ I’ve gotten hold of a Surpass 17T motor, it’s rebuildable and I believe has bearings too…just thinking else can I do…perhaps Turn verse Turn on different manufacturers motors and within a strict budget? 🤔💭🤔any my good friend, god bless and all the very best to you and the family 😊😉
@@JF-RC what if you bored out the ends to a size that would accommodate a common bearing? Just a thought that comes to mind! ! 👍🏻🤔🙂
@@BangForYourBuckRc I think the Mabuchi bushings are larger than standard bearings. I did think to myself why didn’t Mabuchi use standard size bushings to begin with? Seems a lot of trouble and expense for a bespoke bushing size, when they could have sourced more cheaply, standard sizes that are readily available ? Still…I suppose it fuels the parts and hop up industry 🤔😉😊😉god bless
That's a great test. Maybe not tunable, but very robust. I run a boat with this motor on 12 V. Great speed and no damages. Have a great evening my friend.
Hi Dirk, thank you for watching and leaving me a very nice comment. That’s impressive running this humble motor on 12v and it holds up 🤔👍🤔Best wishes 😎😉😊
I am researching here in the US as well…. Keep you all updated
Hi Michael, thank you for watching and leaving me a comment. It would be interesting what you find, good luck with you search. Best wishes 😉😊
keren sekali 👍👍💯💯
Hi there thank you. Best wishes 😊😉😊
Interesting. I think being here in the USA we may have more options for bearings and might be able to do it. Also I’ve always wondered if you could possibly advance the timing on these motors to give ‘em more power. Granted you’d probably have to cut slots for the tabs in the end bell but that’s something I’ve always wondered as well. I might have to look into the bearing options and see what I can find. I’ve got several of these laying around
use to be able to twist the endbell a bit to change timing... Hence locked timing (or notched /flat sided cans) on stock motors, back in the day.
Hi Thad, thank you for watching and leaving me a very nice comment. I’ve got my thrifty head on ….trying to make something better, on a very tight budget 😉😊best wishes to you all 😉
@@UncleBobsRC I thought so. Like the old black end bell
You can always stick it make together and clock the endbell a little bit and give it some timing to make it a bit faster but that is a whole lot of extra tinkering to deal with, easier to buy a faster motor. Not sure if you can get the Holmes Hobbies Retro Sport motor s over there but nice motors for a reasonable cost here at least. By the time the make it there maybe not as much.
Hi Addam, thank you for watching, commenting and leaving me a great tip. I believe there is the Holmes Hobbies UK website and ModelSport website that sell the Holmes Hobbies motors, I will check them out. I’m going through a thrifty phase 🤭🤦🏻♂️🤭seeing if I can get something extra for little outlay…I was inspired a bit by Gino D’Campo’s cooking programme and phase ‘maximum taste, minimum effort’ 🤣😂🤣thought can I apply that philosophy to RC, what am I like eh? 🤦🏻♂️🙇🏻♂️🖐️😎best wishes to you and the family 😉😊
Great video John...... Yeah, I could have let you know this as I took a few apart myself.. The tabs you took off that held the endbell are there to hold the endbell in place... Way back in the day, guys would twist the endbell to change the timing on the motors (CHEATERS), so motor makers came out with locked timing (Trinity Slot Machine was the first I think) but serviceable. Those serviceable "stock" motors you could change the brushes and springs... Some guys put bearings in them (not legal for racing), you could true the Comm also. Good stuff John and again, Great Video!!!!!
Hi Bob, now…if there was one person that would have known, I just knew it wouldn’t have been you, because I’ve seen your videos on motor previously 🖐️👍😎however, I was feeling a bit more of a tight git and was looking to see if you could squeeze a bit more of these cheap humble motors. It’s a shame that Mabuchi don’t make these rebuildable and upgradeable, as it would make it more fun for us twiddlers 😂🤣🤣😂. Thank you for the excellent knowledge and wisdom, always appreciate learning something new 😉😊😉best wishes to you and the family 😊😉
@@JF-RC The Johnson motors are just as bad but you know, they are cheap if you have to replace them. Those silver can 540's run like a raped ape on a 3S lipo, Kevins Clod is proof of that..... Sure, they wont last long but at @ 13 bucks a motor, cheaper to burn those out than two Tamiya motors or two $60 plus vintage brushed motors.... Your better off using a Tamiya Super Sport motor and putting bearings in that/those... At a gain of only @ 300 to 800 rpm......
@@UncleBobsRC Bob, you’re the G.O.A.T! 😉😊😉
@@JF-RC Nice, I'm a Pontiac GTO... LOL
@@UncleBobsRC greatest of all time 😉🖐️😉
Well it was worth it just to find out i guess the only way would be to get bearings and have custom made inserts on it to make it work together but that's a long shoy
Hi Fonzie, thank you for watching my friend. Yeah, this humble motor from Mabuchi is what it is, an entry level motor only, I guess the idea is to help fuel the supply chain for motor and RC upgrades 😊😉best wishes 😉
Lol, just lube the bushing it will perform just as well as bearings but won't last. To make that motor faster you change the timing! You do that by turning the plastic endbell to advance it making it turn way more rpm... Use a power supply 8 - 10 volts and start turning the endbell. You will hear it start to scream but too much advanced timing and the brushes will arch and burn. The trick is to get a modified can that has adjustable timing and bearings and put your stock armature in it. You will come up with a motor that has amazing mid-range torque and good top end, the downside is they get hot and burn but who cares everyone has a ton of stock motors they don't use but trust me they can be modified to go a lot faster. ✌🏼😎👍🏼
And if you don't want to change the can just cut new tangs in the stock one after you advance the timing, you can even just glue it back on if making new tangs is too hard! Lol! 👍🏼
@@mikesrcgarage hi Mike, you are a true gentleman and a fountain of knowledge. I was thinking about timing advancement too, but was also concerned of armature support, as I’ve had to cut the tangs away to get into the 540 motor and making the motor that bit quicker with inadequate support, I was thinking ‘boom’! Imploding 540 motor 🤣😂🤣🤭best wishes and god bless to you and the family 😉😊😎
If you think about it tamiya did the sprint and endurance 540 type motors that had one bearing in the inner end but just a bushing on the end bell part! I wonder if tamiya could not find the right size bearing?
I was always interested in the sprint and endurance with their super cool red or blue end bells and black can with that one bearing was like modified coolness back then Iol!
Fun vid because how many motors have l pulled apart over the years but never pulled a standard silver can 540 apart!
Hi, thank you for watching and leaving me a fantastic comment. Interesting comments about the Sprint and Endurance motors, also not having full bearings in their configuration🤔. I was looking to see if the modest standard 540 could be made just a bit better, but alas, beaten by unidentified bushings. 🙇🏻♂️best wishes 😎😊😉
Hello, thanks for the video. Did you manage to replace the brushes?
Hi, thank you for watching. Sorry, but the Mabuchi RS 540SH has bespoke bearings, which I haven’t been able to source. Therefore I’ve deemed it as having no serviceable parts and consider it as a disposable motor. 😉😊😎
@@JF-RC thank you. I do wonder though if you wear out the bushings or the brushes first.
@@space_cowboy007 it’ll be the brushes first, the bushings are very tough. Just a shame I could find bearings, as I was interested in the performance difference between a standard 540 with bushings and a standard 540 but with bearings. 🤔🧐
@@JF-RC in our club one porsche cup racer said the brushes died after about 3 hours / 80km and that durability was the only reason to invest in 17.5 brushless as a replacement as it has equivalent performance.
i have one , and i want to use it for an rc car , i don't know how much current it would draw ? and what esc/lipo batteries type to get to run it fast enough ?
Hi, thank you for watching and leaving me a nice comment. The 540SH motor really isn’t too power hungry to be honest. Probably draws between 6-8Amps at best. In terms of an ESC, this is a tricky one, it depends on what your putting the ESC in? the most popular would be a HobbyWing WP1060, that way you could always upgrade the motor, as long as your above 12T on a 2S LiPo. The HW1060 can accommodate 3S LiPo’s too. Battery choice is always a tricky one as well, it depends on what RC your going to be running, buggy, touring car, rally car…? LiPo’s need to be cared for carefully too. If you’re starting off, I would go for a decent NiMh pack, they are easier to care for, then once up and running, go for a LiPo pack, once you’ve got a place store them and a good charger to charge them. Hope that helps. Best wishes and a Merry Christmas 😊😉
I wonder if the armature would work in a modified can.
Hi Kev, thank you for watching and leaving me a great idea…can the armature fit into another modified 540 can and magnet system? That’s a good question…you’ve got me thinking again 💭🤔💭best wishes to you and the family. Congratulations on 102mph ! Awesome 🤩
Always glad to help.
EXCELLENT✅😁👏🏽
