Selecting an esc based on scale it helps if its meant for track racing with limitations or rules when it comes to the motor.. Motor KV plays a part too.. especially for drag and speed runs, so selecting an esc based on what is mentioned on this video or scenario may differ..my 2 cents
Thank you for your information. I agree that electronic equipment selection according to scale is not good. Many people are confused about what equipment to put in their vehicles. so weight of a vehicle desired velocity gear ratio with three pieces of information motor KV motor watt anticipated heat generation I would appreciate it if you could make a simulator that can calculate. In RC airplanes, these calculators have existed since 10 years ago, but there seems to be no RC car. It would be nice if you could make it.
Yes but how do we determine the max amp draw limit for a given esc? How do you choose between two 1:8 esc? Which one is more reliable? What are their designs intended for? Many r/c enthusiast have the knowledge to make their own calculations to reach their goals but they cannot do that with missing information. This is as assuming manufacturers are producing esc and not know their specifications and ratings? Scale sizes is virtually irrelevant as ppl are adding other/larger components to a 1:16 to reach 100mph and other 1:8 scales ppl are removing weight to make them lighter In addition to swapping to a more powerful electric motor makes the ENTIRE scale reference inapplicable. We need the specifications.
Anyone searching for this type of information is already passed the RTR stock out the box setup and are looking to level up.. Everyone else would think to them selves., oh okay I see…🤔 and then have a million questions about motor selections.
@@AutoBodyEverything here I am, in exactly this case... Currently designing my own RC car FROM SCRATCH. What's even worse, is everyone talks about scale, yes I know the "scale" I'm aimed within, but pretty much all these vehicles run a single motor, and single ESC. I'm designing for a motor and an ESC PER WHEEL, with then a huge "brain" controlling it. It gets very annoying when companies can't place normal electrical ratings on items, give me peak, give me continuous, give me temp ratings, hell, I'll even take the resistive ratings so I can calculate the thermal load! I'm attempting to avoid needing to design my own ESC with the current global electronics shortages going on...
@@thedevelopmentlab …. This design sounds like that concept rc with an out drive motor on each wheel and a main control unit almost like a drone platform. Kev T had it on his Chanel and it broke piece by piece bcs some parts were printed like the rims and the whole thing failed bcs of poor hardware integrity. The electrics on the other end worked well and I still have high hopes for its return. I think it was MAMMUTH works.
Yes I saw that RC car, it was pretty cool. Theres advantages and disadvantages to how they ran their system. Advantage is size and space. Disadvantage is a dramatic increase in unsprung weight, which makes it a lot harder for the suspension to do its job of keeping the wheel in contact with the ground. The setupi described of mine is only stage 1 of my whole design process, ive got a lot of fancy ideas on the draeing board :) It will take a LONG time for me to finish it however, ha ha
Man so you mean that if the scale of my RC is 1/10 , and my motor is enough with 45A, doesn't change anything if I mount a 50A or 110A ESC ? should I get more benefit anyway with the 110A? thank you 🙏🏻
Hi, I am planning on getting a 1/10 short course rc car weights about 6 KG I have seen videos and it's not very fast so also getting a bigger motor. The RC use 3S batteries and come with a 120A ESC and Surpass Hobby 3660 2600KV says on the specifications chart that has a max amps of 63A and Io of 1.5 A and running around 33K rpm on 12.6V, I was planning on get the Surpass Hobby 3660 4200 KV the chart says max amps of 100A and Io of 3.7A this on 3S 12.6V get over its 50K RPM limit by 3K rmp so I don't if that little exceed rpm will be tolerated or the Surpass Hobby 3660 3500 KV the chart says max amps of 92A and Io of 2.8A has a 44 K rpm on 12.6 V both motors has a max rpm of 50K, do you think the 120A ESC will do the work or increasing the KV of the motors would reduce the initial torque and current against the original 2600KV so there won't be any problem with the upgrade, that 4200 Kv is the more powerful in the 3660 size but there is also the 3500 and 3100KV so this is also and option, also mention that I can't change the ESC or the gearing so my only option on increasing speed is by the motor KV or maybe get a 3674 motor 3000Kv. Thank you for your time and great content.
You can select any motor that you are comfortable. The motor will only draw as much power as it requires. If you gear it very conservatively, a 120A esc will be fine. Check Temps afterward.
@@RCexplained Ok, so would you recommended go with the same length on the 3660 4200KV those 3K rpm over the 50K max rmp limit would afect the motor or not? Also would be better getting the 3660 4200KV or a motor with much torque and speed like some 3674 3250KV? Not really sure if is better to get much more Kv or just a little increase but much torque, I guest I as I want speed I should go with the 3660 4200Kv.
Shoot I had my 1/5 kraton exb out today at the park pulling wheelies at 76mph lol per GNSS I can only imagine how many amps I was pulling haha I have to check out my data logs on my xlx2 I have the 1100kv 2028 on 39/34 gearing and temps are 125 ESC and 119 on motor.
Your content is awesome. I hope your channel grows bigger.
Thanks for the comment!

Thank you for your information.
I agree that electronic equipment selection according to scale is not good.
Many people are confused about what equipment to put in their vehicles.
so
weight of a vehicle
desired velocity
gear ratio
with three pieces of information
motor KV
motor watt
anticipated heat generation
I would appreciate it if you could make a simulator that can calculate.
In RC airplanes, these calculators have existed since 10 years ago, but there seems to be no RC car.
It would be nice if you could make it.
Awesome 👍🇨🇦👈🤠

Great
Im looking for a speed controller to race in a 2wd buggy, what are your recommended models,? Thanks
Monster x is my choice.
Man so you mean that if the scale of my RC is 1/10 , and my motor is enough with 45A, doesn't change anything if I mount a 50A or 110A ESC ?
should I get more benefit anyway with the 110A?
thank you 🙏🏻
No difference. The 110A ESC will run cooler and be more reliable as its not pushed as hard. That is about it.
@@RCexplained K, thank you 🙏🏻
How to select esc with how much kv's motor is best
For example how much amp esc is need for 5900kv motor
Using kv alone is impossible.
How i find the right values even about motor first 🥲
What is the diameter and length of the motor case?

Thats the motor and speed control i am putting into my 1/8 scale buggy. Should be pretty fast.
Second nice 👌
