Brushed vs. Brushless motors - Top 8 reasons why brushless 

Brother, start with a Traxxas TRX4, you just can't go wrong with that Crawler! If you like building kits, you can start modding from the ground up. And there are a crazy amount of upgrades, motor/esc's, servo's, light kits, wheel/tire combos, bodies,,, etc. Though the model is a bit dated, it still holds it's own with the best out there. Happy Trailing!!

This is my goal. Share knowledge so folks can maximize their rc fun

@@shuster1921 trx4 sport kit is my favorite

@@jackking5631 id recommend getting the scx10.3 I find ot better than the trx4 but that's my opinion it all depends on what and where your going to take it on the trails

I easliy spend twice as much $ a year on my cars than I do my planes or fpv drones....the only time they need fixed is when you crash. Also way less wear items on aircraft vehicles from my 5+ years of experience.

True, but that is true for everything with regards to equipment. 80-90% of it is driver skill. But the best way to look at it is you competed with a person of equal ability as you (such as yourself) and they had a way better motor/esc system, they'll do better each time.

@@RCReviewChannel.. I totally agree, Francis! Once you have "outgrown" your stock rig, it's time to fine tune your abilities with a more competent rig! I've grown to get excited when you release new videos, you're one of my favorite!

I agree mostly. On 3s we run 4 1/2 hours then run out of sun light. Some rigs I’ve had no problems with box stock form with stock tires. I don’t have any crawlers in brushless but I do want one with a brushless. But there’s none that I seen with 100% drag brake and higher wheel speed together.

Your comparison holds true ONLY if you had a less skilled driver around. At same skill levels you would not have outrunned anyone. I'm happy you are happy with your driving skills but don't underestimate the importance of the hardware though, cse it can change A LOT.

Did you really just flex your years of crawling experience in a RU-vid video comment section? smh 🤦🏻‍♂️

I love that I can still understand them and organize my random thoughts. :)

@@RCReviewChannel hahaha

Yeah it really helps for a newbie like me.

Great to hear!

That's what it's all about... testing and outlining of pros and cons. Personal choice comes at the end when enough knowledge is gained to make a choice.

Yeah, i simmered the content in my head for about a week

i don't know how I came up with it.... 8 & 2

Glad it was helpful!

That's what it's all about. The right tool for the job is so satisfying.

Don't neglect the motor bearings. Moisture always finds a way in. So periodically open the motor up, clean and reoil the bearings.

True, but I have to outline it for the most easily understandable and watchable summary for most folks. My least favorite statements from 'experts' is: "it's all personal preference." :)

Try the Spektrum Firma 2 in 1, 2300KV. It is awesome. Fast, powerful, butter smooth oozing crawl with big torque and immediate throttle response. It is also completely silent.

You are so welcome! Knowledge is power!!

Glad you enjoyed it!

Diamond servos are getting some attention. I may have to get one too

Glad you think so! We gotta keep modding and learning.

What motors are you using?

Yes, Mamba X offers up to 10 amps of BEC. snp.link/3da83c18

If you are working with off the shelf components then some of this might make sense and actually be real. The push from manufacturers has been profit and this means built in obsolescence, complexity, and chance of expensive failures maximised. If you have a brushed motor the power rating is its all day everyday never cause a problem rating. This is NOT the case with brushless motors and controllers. They will invariably blow up if you exceed the rated power, often even if you come close to it. Brushed motors can usually deliver 10x their rated power and much higher than their rated speed for 10sec or even 10minute bursts. Efficiency of a brushed motor is better than a brushless, because you cannot avoid the voltage drop of switching semiconductor junctions with an electronically commutated synchronous AC motor. That is what they are. They are not brushless dc. With a brushed motor you can use switches or relays to directly connect to your battery for maximum efficiency and power. Do you see brushless electric starter motors in full size cars? No. Because they can't produce the torque, power, and reliability of a brushed motor running at high speed with reduction gears. They are sealed units too. As are many ebike, industrial, light electric vehicle and things like forkhoist motors. You can't make any sort of decent power without cooling. So that will tell you immediately that a sealed motor of whatever type is capable of a fraction of what one with forced air cooling. Unless of course it has liquid cooling via circulating ducts. I would never consider brushless for powertools, transport uses, harsh environments like marine ones, anything but GENERATING Electricity where all you need is a bridge rectifier to make it into something useful. The high frequency of ESCs will cause corrosion and failur anywhere near salt, or geothermal gases in days. It is also very bad for human health and brain function. Perhaps why so much of this review is nonsense. 🤭 I've seen too much heart and wallet breaking from people trying real world applications with brushless. Would you rather replace a 50cents brushset that can be trusted for at least a decade, or thousands of dollars on a esc that burns out the first time you power up, or something goes wrong somewhere in your electric or mechanical systems. The manufacturer wants that second option, and that is why they overhype and fraudulently describe them as brushless dc motors and claim that anything about them is new. They are Nicolai Teslas mistake.

@@aaronfranklin324 can I see video of some brushed motor drones? I think thats what I wanna get into. All these fradulent people thinking they can push supposed newer technology just to steal money from us. I refuse to go green and buy an electric vehicle until they make one with a brushed motor, world is going to be sucking my carbon forever I think.

Same, same.

Brushed can do 4s?

@@RCReviewChannel Limitation is not the brushed itself, rather the availability of rc ESCs that can do that. For example in robotics it is quite easy to find one.

@@RCReviewChannel yes with the right motor wind. escs are hard to find though

Thank you! Will do!

There you go. Right tool for the job.

It's so hard to beat for value

Rock on then!

Glad I could help. That is music to my ears as we want folks to buy the right product for their use.

You are most welcome

Thank you for the input!!

Great point!

Yup, it's not an easy choice since you have to buy the whole system right away. But now you know the trade-offs.

@@RCReviewChannel hello Francis. Great vids and info. New subscriber to your channel and somewhat new to rc in general. I have a question and I’m not sure if it relates to brushless vs brushed motors. I’m building a rig with HUGE tires and wheels. Each wheel and tire set will weigh about 2lbs each…so about 8lbs total for tires and wheels on my rig alone! My rig will have 2 uses: - when it’s sitting on the huge tires/wheels, it will not be used for bashing or racing. Maybe not even crawling. The main reason will be for a show here and there, when I have time. Mostly it’ll be for my viewing pleasure 😂 but I still want to be able to drive it. - when not in “show” attire (body, bumpers, wheels and tires) I do plan on running it on standard 1/10 scale tires and wheels as a monster truck with some light bashing. With all that being said, I have 3 questions… 1) Does it even matter if it’s a brushless or brushed system? 2) What type of system would you recommend? 3) What type of servos would you recommend for the weight? (I may decide to make it front and rear steering rig) I’m building this all on an Axial SMT10 raw builder kit. I know it’s a lot of info, sorry. But your input will be greatly appreciated. Thank you!

There you go. Now you know the trade-offs.

I’m running a Tenshock 1750kv 6 pole sensorless motor and a castle sidewinder ESC, ESC was 79.99 USD and motor was 37.99 USD, I will never go brushed again! Super low crawling speeds tons of torque/drag brake, and really nice top speeds! No cogging at all aswell!

@@resideracingrc5658 thanks for the info! I am going to have to try brushless!

I'll work on it. The different types of brushless....

@@RCReviewChannel awesome!!! can't wait!!! When you do it... i'll know it was for me. hahaha.

I have been flying planes, helicopters and drones for 10 years. Brushless is the way to go with those period! Crawling? Nah, the brushless systems to me just cant go slow enough. With brushed motors you can creeeeeeeeeeep so smoothly to where brushless requires a certain amount of power just to spin the motor and it causes cogging where the motor starts/stops/starts/stops really fast. Not good with crawling. Stick to brushed motors for crawling and you will be happier in my opinion. I have about 5 crawlers and they are all brushed, I have been driving them roughly 2 hours every other weekend for the last 3 years and I have yet to replace a brush. This is my 2 cents.

@@explod329 yep. I remember brushed motor hell in the 80s with the r/c10 cars and the quick change brushes and hand winding commutators… first came the electronic speed controllers that killed the servo motor wiper throttle and then the brushless motors. But ya with crawling I guess I could see the point since at that point a brushless would start acting like a stepper motor.

Ooh, I'll look into that

Thanks for the info! More maintenance but I can see the modulation argument. Perhaps a sensored brushless would be good for that application. Smooooth!
