Thanks for the vid Ryan. I suppose we don't know how much redundancy is built in to a motor. It's a bit like chip-tuning your car: You might get away with a 5 - 10% increase in power output (for example) without sacrificing much in terms of reliability, but anything more could be a risk. Well, at least an RC motor is a lot cheaper than a car, so a little risk-taking is ok I guess!
Luckily for our motors, we will know when we hit the limit when the motor is over temp. Unfortunately for full size cars, you won't know you are at the limit until a rod comes out the side of the block.
Another good video - I've been binge watching your series like Netflix lately! Question: sometimes manufacturers quote maximum efficiency specs for motors. Do you ever take this into account when selecting a motor?
I usually do not as not all manufactures provide that specification. If they do, it doesn't mean that the configuration planned to be used will be able to hit it.
Is there a reason that you rarely see people use thermal paste with heatsinks and motors? I can't think of any but one assumes that would greatly improve the cooling performance.
Rc car people need to talk to PC people. PC people know that a large heatsink must be in as close contact as possible with the cpu for efficient cooling. Most rc car heatsinks have huge gaps with very little contact between the motor and heatsink with no thermal compound and with teeny tiny over revving fans.
It would definitely help thermal transfer. I wouldn't want to use thermal past on the motor just because it tends to be quite messy. But if I wanted to win a race or gain an edge, I wouldn't think twice. ;)
@@toolbaggers this was entirely my logic. My buggy's heatsink slides all over the place, definitely not good for heat transfer. It's running pretty cool so no point but if I run into heat issues that's the first thing I'm trying. My bet that will do way more than sticking a bunch of extra fans on.
@@RCexplained thermal compound makes a HUGE difference in the world of PC cooling. But unlike in rc, it's very very easy to conduct repeatable, and well defined testing methods that PC gamers do when overclocking their rigs.
Thanks for the info. So as long as I don't exceed the max rpm or overheat the motor I can give it the voltage needed to get my desired wheel speed? Still trying to decide what motor to try in my Bomber next.
You need to keep the rpm to a maximum 90% of the motors total rpm rating. This will ensure you keep motor in its thermo dynamic range. Remember if you run a 50.000 rpm motor at 42.000rpm You have reached the maximum safe thermal threshold of the motor !
Absolutely nothing wrong running a 32pitch with a 0.8pitch gear. If the mesh is lined up right, the difference in pitch isn't even noticeable even running the car over time. Never cross a pitch like 32p with 0.6p or 48p but 32p with 0.8p is fine.
Your videos are so important Me and my mate ran a 6s blx arrma motor on 8s and it was good for a few months which was enough , Do you get email on data log , Waiting for xlx2 Thanks for another interesting video

Wow. Fantastic info
Glad you think so!
So if I have crazy game changer fans for my motor that literally run on a 3s 2500 mah lipo and wake neighborhood up can I gear to the moon?

I usually do not as not all manufactures provide that specification. If they do, it doesn't mean that the configuration planned to be used will be able to hit it.
I guess if you have a large enough rc, you might be able to figure out how to mount a pc radiator, pump and water jacket to keep the motor cool.
500watt max means it has a real world rating of about 350w under real world conditions. The Chinese manufacturer doesn’t care about real specs .
Thanks for explaining ryan, this helps me tremendously with rpm value and the voltage of a lipo battery pack to use safely within that range
Great to hear!
My morning starts with some good video ;)
That is awesome!

Then you pc builders that have 20 different wires for 12 volts on multiple connectors when they should just use larger gauge wires.

That is correct. The hobbyist also assumes all risk when exceeding a manufactures max voltage limit.
You need to keep the rpm to a maximum 90% of the motors total rpm rating. This will ensure you keep motor in its thermo dynamic range. Remember if you run a 50.000 rpm motor at 42.000rpm

Thanks for the vid
Thanks for watching Eric, and nice chatting with you!
Anybody try wrapping copper heat pipes around an rc motor for cooling?
Nice videos man u have me in a much needed class I'm new to rcing hobby thankyou u think u can put a build
Thanks for the comment. I'd like to do a video with a build.
Great vid bud
Thanks!
Dense info much satisfaction. Thank you sir!
My pleasure
Very helpful!👌👌👌

Do you get email on data log ,
Waiting for xlx2

Thanks Cmw. I did not receive an email about a data log.
TMI ugh I’m more confused as to what motor I need
RTR is for you.
Extra Tom in that sweater
Oh, Teton gain :)
The Teton fits on the desk quite easily!
