Just came across your channel. Thanks for the info. What esc/motor combo would you recommend for a Losi Drag car roller? I currently have an unused castle sidewinder sv3 combo 3800kv. Thoughts?
What outrunner motor is used in this video? And would you use yourself an outrunner motor on a drag car which sees bout 20-30 sec max throttle.punches on a drag strip?
I'm sorry if I missed it but how do the measure out sizes of motors like a 3650 size. What does that 3650 stand for? Like if I have a certain length, width motor how would I know what size that motor is? Measure it? I'm wondering about sizes. 540, 550, 3650.....Thanks
Hi Chris. 3650 is the size of the motor measured in mm of the outer case. The motor would be 36mm in diameter and 50mm in length. 300, 400, 540, 550 is the classification of a motor more typically used for brushed motors. The bigger the class the larger the motor.
I've got a question about brushless. I've got a 4×4 1/10 buggy and I want to convert my brushed system 15T motor (which i run it with nimh 7,2volts, 3Ah) to brushless combo 3000kv motor and 50A esc and still run it with the same battery. Would it be faster or slower??
Great! Can you share the analitical formulas and all calculations for designing the BLDC? Maybe some book with example of designing some motor. Or there is a online calculator, where I can obtain the dimensions of stator, rotor, aor gap, and winding turns, poles number, and slot numbers for concrete power and speed. Thank you!
I notice that racers within a class with open motor rules still tend to choose one kv rating, citing that it "hits the sweet spot" or power band. For example, in 4x4 SCT, it's 4300kv on 2s, and 1/8 buggy is 1900v on 4s. Since these are not ICE motors, is there actually a power band or sweet spot with brushless motors(besides exceeding the max rpm range of the motor)? Using the 4x4 SCT class, is running the 4300kv motor at 31,820rpm really advantageous to a 5100kv motor at 37,740 rpm with a smaller pinion? Thanks for any insight.
I would disagree with the argument if the motor is not using close to the full rated allowable motor speed. If this is a 60,000RPM rated motor, operating at 31,820 is leaving motor performance on the table. If the argument is that more power is not needed as the car becomes incontrollable, this is a different argument that is vehicle specific. th-cam.com/video/0W07RLdj6w4/w-d-xo.html
So I have a question. I have a Traxxas stampede 4x4 vxl that has been sitting for quite some time. I went up to the local hobby shop and it was determined that esc and motor went bad. I ran this setup years ago and always had over heating issues. Well they sold me a Castle Creations Mamba x with a 1406-2280 motor. I think I messed up by listening to him because it wasn't what I expected for the "upgrade" it's geared at a 17t but it's really not fast on top end and actually has an annoying high pitch sound when running. I'm running a 3s lipo but I'm just not satisfied with it. Any suggestions? Did I fuck up by adding such a low kv motor? Any help would be appreciated. Thanks
Hi Sam, if your motor, ESC and batteries are not operating near max thermal limit, you can gear up. The noise you hear could be from the gear mesh. See if your gear mesh has the correct spacing.
Looking for a brushless motor to replace my 34lbs Minn Kota motor. Reason: efficiency. But how do i determine the needed specs? I know the Minn Kota has 1200 ish rpm (read it somewhere) so with a 12V LiFePo4 I should have a 100Kv motor to get the amount of rpm, right? But how will i know the motor is strong enough? Thanks for your informative videos!
Hi Ardy, the kv you selected will get you to 1200RPM unloaded. As soon as you load the motor, RPM will drop. Going with 110kv, will get you closer to 1200RPM loaded. You will also need to know the power consumption of the Minn Kota motor. My suggestion is to measure the voltage and current under load as it is mounted to your boat and at full speed. Multiplying the voltage by current will get you wattage. When you know the continuous power output of the motor you currently have, you can select a new motor to match this output. That will be a good starting point.
@@RCexplained Thanks for your reply Ryan! Max current is 30Amps at 13.1V. So that would make about 400W. With losses accounted that would make 440W minimum. Rounded up: 500W total. What would be your next step? Thanks in advance!
Hi Ryan, I've watched some of your videos to understand the concept better. The only question i have for you now is the following: Assuming that the motor will use 440W on 1200rpm, can i select any BSDC motor with a high enough max Wattage? Or should i determine the Wattage by divide the max Voltage with used Voltage(my LiFePo4) and divide that factor of the max Wattage? Little confused here :)
Hi Ardy, you will have to find a ~500w motor with around 110kv to reach your 1200RPM. Your motor would then need to be able to operate at a continuous current output of 42A. The specs you need are: Min 500w 110kv where 12-15 volts will not exceed the motors maximum rated RPM. 42A minimum continuous rated current
please help me decide...i have a kraton exb and dont know what to put in it.....i will run 6s battery but dont know what kv motor to get....im planning to get the max 6 esc but what kv? also what gearing should i use when i will put a heavier tire so that it will not affect the motor?...more on bashing and a lil bit of speed...thank you very much...
I have a 1 10 scale RC car for bashing and I am looking for a motor that could make this car wheelie and still be fast I was thinking about a 3500kv motor and 4s lipo, I want to buy a cheap esc and motor combo but are they good enough to run 4s or do they get to hot a lot of these cheap combos should be able to run 4s if I read the description but is that true or do they end up in flames
There are inexpensive options that do provide adequate power. I don't have a lot of experience with those options, however, there are many posts on threads about them.
so I'm building a 1/10 scale baja trophy truck thinking Im going to use a 4 cell so what brushless motor would u recommend? want decent power n speed. Also still pretty new to all this
Hi Colton, I prefer Castle motor and ESC setups. My suggestion is to hop on a forum with your specific truck and see what the guys are running. This should allow you to get a good understanding of how each setup performs. These guys would have a lot more experience with these setups in that truck than what I do.
Hi Ryan, thanks for explaining this part. All clear for now. How about torque? If I have a 3650 1200KV or a 3674 1200KV, both on 4S. RPM should be the same unloaded. But loaded I assume the bigger (3674 in this example) motor should do more RPM or am I completely wrong?
Hey BlackbirdAirbrush, thank you for the comment. To answer your question the larger motor of equal kv will be able to produce more torque. This is true as the internal resistance of the motor will be lower allowing it to draw more current. Current is directly related to torque output. The larger can size of the motor is then able to dissipate more waste heat that comes along with the higher current capability. Here is a video on comparing Brushless motor Torque th-cam.com/video/xi7jxIkX2vY/w-d-xo.html
hello , wish to ask you a question , if a motor specs will say max voltage 48 volts max amps 208 max 10000 watts but continous power is 5500watts , if i give the motor 37 volts will it draw same 208 amps or less? or will it draw according to its load ? motor is 1170kv and i wish to get out at least 7000watts ,what is safe to do ?
Can a bigger bullet connector on your motor lower motor temp? And is it ok if a motor peak amp is higher than the esc constant amp rating pertaining to drag racing
I would not expect a larger bullet connector on the motor to lower motor temperatures. Larger connectors lowers the resistance of the connection point, increasing the voltage that the motor sees. In theory this would increase motor temperature as more power will be sent to the motor instead of being wasted as heat in the connection point. I would expect if you are already using adequate connectors, moving to a larger connector will have negligible difference. Peak current that happens in short bursts under high load often exceeds the constant rating of an ESC. Watch the data log video I have. The ESC was not rated for 300+amps. Limit the duration of the burst, only make a couple passes and allow everything to cool before the next drag race. Using the ESC's for demanding applications such as drag racing has a degree of risk associated with it. To minimize risk, use the highest rated ESC, a cap pack and monitor temps.

I thoroughly enjoyed your video and all of the good info that you provided, you made it very easy to understand. I subscribed. Thanks..... I do have a question... how are tp-power motors able to provide so much more RPM/KV per volts than competitors? I've been wanting to purchase one for my limitless I believe it's a 2700kv and is rated for 8s. What are they doing differently than the other companies? Thanks for any info you can provide.
Hello, thanks for your comment! That's a great question! The maximum 80,000+RPM the TP Motors have are based on bursts no longer than 10 seconds. It also states that CM series motors are intended only for experienced racers where standard factory warranty does not apply. Does this mean the motor could be ripped apart but its at the customers own risk? If so this would apply to any motor really. Make up your own specification based off of trial and error. I will see if I can find out more information from TP-Motors and also other manufactures. If I get anywhere it will become a video topic. I'm super interested in what I find, this is a great question, thank you for asking. Keep in mind that my video queue time is well over 4-6 weeks right now. Not sure which manufactures will reply in times like this either.
Thank You for the comment Doug. Higher max wattages will drive torque potential up. I have a more recent video talking specifically about torque. th-cam.com/video/xi7jxIkX2vY/w-d-xo.html
I have a question for you would I notice the difference between a 850 KV to 880 Kv or is there not going to be that much of a difference the reason why I'm asking I have a 850kv in my plane now I want to switch it to an 880 not sure if it's worth the money
Thanks for a great video. I'm currently working on a robotics project, and i've always used brushed dc motors, just because of the simplicity. Now i wanna step to using some brushless motors for some more power, but after watching this video and your Inrunner Outunner, i see that it's not just as simple :) Is there anyway to know how much torque to expect from a brushless motor? Normally i would maybe buy an already geared dc motor, but that doesn't seem to be a common thing for brushless?
Hi Christian, I have not used a geared brushless motor. Typically the application we are placing the motors in already have there own transmissions to sort out the Output RPM. Otherwise the application is direct drive. There are many brushless options out there. One thing you may want to look at is if you need to go with a sensored motor or sensorless. A sensored motor will give you a cleaner start up from 0 RPM. (similar to a brushed motor) A sensorless motor would not be as clean. Yes there is a way to determine expected torque. Kv and Kt are both motor constants that relate to each other. You can find one to determine the other. Kt is measured in newton meters per amp. Then you just need to determine the maximum continuous and/or peak current that the motor is capable of and you will know the torque output. Don't forget to hit that like button if the video has helped you out. This helps encourage me to make more! Thank You
Great video. Very informative. I'm looking for a new motor for my Rustler 4x4 vxl. I want to hit speeds over 75 and I don't think the stock brushless can do that. Btw that's an awesome picture behind you.
Tell us Step-by-Step how to rewind the stator and the proper way to change the rotor for a given KV and/or performance for an intended purpose for a Brushless Motor, please. This is for us who are curious and a little more advanced technically. Thank you.
I want to run my traxxas rustler SUPER FAST and I’m buying a castle motor Castle Creations SW4 12.6V 2A BEC WP SL ESC 5700kv with the stock upgraded pinion and spur gear. Will that work?. And plus I’m not trying to spend $300-$400 on a motor
Hi Terry, your esc and motor choices seem fairly good, hiwever, I've never owned a rustler. My suggestion is to read up on a forum to see what others are doing. You should be able to get an idea of the speed you can achieve.
@@RCexplained also dont forget your gearing..a higher pinion gear teeth count and lower spur gear tooth count will have you doing warp speed..but the offset is your lower end will be slower..a good combo i found was 70 tooth spur with a 21 tooth pinion..it also made my motor temperature and esc higher....if ya wanna go really fast go steel gears .. 1 to 1 ratio
What specifically are you looking for? Relative to a baseline motor already being used in your RC - A higher kv will make your RC faster if your system is up for this increase in current required. A lower kv will be slower.
If newbie watches this all there gonna do is pick the highest rpm motor. How can you do a video like this and explain nothing about torque. I am very confused.
I already know about torque and everything else. I'm just saying if a newbie watches this they don't know that and you don't say nothing about there is another video about touque.

Then you just need to determine the maximum continuous and/or peak current that the motor is capable of and you will know the torque output.

Great video. Very informative. I'm looking for a new motor for my Rustler 4x4 vxl. I want to hit speeds over 75 and I don't think the stock brushless can do that. Btw that's an awesome picture behind you.
Thanks for the comments Talon. Are you thinking of upgrading your system? Is that 75mph?
Shouldn't vxl hit 75 with the right gearing?
Tell us Step-by-Step how to rewind the stator and the proper way to change the rotor for a given KV and/or performance for an intended purpose for a Brushless Motor, please. This is for us who are curious and a little more advanced technically. Thank you.
thanks
Very good content! Liked and subbed also. I watched the entire video and look forward to learning more. Im a basher trying to learn more. Thank you!!
Thanks for the awesome comment!
I want to run my traxxas rustler SUPER FAST and I’m buying a castle motor Castle Creations SW4 12.6V 2A BEC WP SL ESC 5700kv with the stock upgraded pinion and spur gear. Will that work?. And plus I’m not trying to spend $300-$400 on a motor
Hi Terry, your esc and motor choices seem fairly good, hiwever, I've never owned a rustler. My suggestion is to read up on a forum to see what others are doing. You should be able to get an idea of the speed you can achieve.
@@RCexplained also dont forget your gearing..a higher pinion gear teeth count and lower spur gear tooth count will have you doing warp speed..but the offset is your lower end will be slower..a good combo i found was 70 tooth spur with a 21 tooth pinion..it also made my motor temperature and esc higher....if ya wanna go really fast go steel gears .. 1 to 1 ratio
@@karlfritz47 Hey Karl, thanks for your comment.
awesomeee
Many Thanks Sir Masteryan !
I’m not smart enough to understand everything this scientist slaps my brain with.
The only problems I have no body tolks about if you got a 40amp/160 esc what the smallest battery 2 biggest battery can you run on that
I don't understand the question. You can use a battery from 0 to infinite in size with a 40A or 160A esc. The ESC doesn't care.
He looks like Steven Wilson :)
Are you an electrical engineer or is your knowledge based on experience and time
mechanical eng (Do a lot of DC electrical work) and experience/time in RC.
I mixed up the rotors for a 1,400 and 2,200 kv motors. I’m stupid
Can you give me the explanation of kvs for idiots please do more kvs make it faster or slower
What specifically are you looking for? Relative to a baseline motor already being used in your RC - A higher kv will make your RC faster if your system is up for this increase in current required. A lower kv will be slower.
RCexplained I have rustler Vxl but my Vxl motor got toasted
@@Happygrowercbris420 What was the temperature that it was running at before it got toasted?
RCexplained I have no idea but I had 4 Nickle metal battery’s throw it before it happend
You will want to know the temperature of a newly powered RC. If you don't, you are operating it I'm the dark. That's too risky.
Hey man I need some help bro
What do you need?
If newbie watches this all there gonna do is pick the highest rpm motor. How can you do a video like this and explain nothing about torque. I am very confused.
Hi mark, have you watched the video on torque vs kv?
th-cam.com/video/xi7jxIkX2vY/w-d-xo.html
I already know about torque and everything else. I'm just saying if a newbie watches this they don't know that and you don't say nothing about there is another video about touque.
That is exactly my point!
I need to figure out what kind of motor I need plz text me back thks.
What do you need?
I gotta figure out a motor that going about 80,000 to 90,000 rpms and not blow up
And its gotta spin a disc very fast it's a project I'm doing and no I'm not in school I'm 19 just graduated 2 years ago but it's very important
@@MattRoberts369 for what application?
What you mean
so i think, unless im mistaken, something like an arma limitless running 8s would do well on a 1530 motor?
Feedback from anyone is appreciated
That would work well.
Thanks
