Any OG's in here remember using those optional heat sinks on the ESC's in the brushed motor days?

[@jiveafrica4232]

LRP OPC SR Anodised blue press fit which would fly off 30sec into every run😊

[@brianmonroemodelsports21]

Back in the old days I went one better. wrapped small diameter copper tubing around motor and flushed ice water thru the tubing just before the race. that was in the mid to late 80's. don't know if that would be legal now

[@nibs6933]

I'm running one on my MI, which is something I bought many years ago to have fun with. I also run a heatsink on the motor in that car.

[@herec0mestr0ble]

Tinker Aholic now that’s racing lol

[@denniszellers6423]

Had the old tekin esc's with the two small gold heat sinks.....those were the days.

[@lisalouisekeen4191]

Great tips hun. I bit the bullet couple weeks ago and got an old xb4 15. Running it in 13.5 blinky. Ran it for the first time last week. Big learning curve after running tc and on road for so many years. Last time I owned and raced a buggy way 27 years ago and that was a tamiya falcon. Enjoying it so far brings a big smile to your face. Buy I will always be a tc girl first.

[@mikeinvegas1]

Came across your videos recently. Getting back into the hobby. Especially not stuck at home during coronavirus era. Thank u for great videos.😊

[@jedovtqy4533]

Nice tips Ryan, To keep my cars cool I stay living in the uk, it's always cold here, lol

[@ollilavikka8014]

Great and very informative video! I personally also like to change the timing of the motor in order to degrease the temps when I'm out of pinions or if the motor is running consistently hot regardless of the gearing. I have also noticed that if you run low timing and high gearing, the efficiency of the motor is much better than if you ran high timing and low gearing while sustaining the same level of power output.

[@RyanHarrisRC]

Great advice and very much agree!

[@theprorcguy]

Meanwhile I'm over here and my motor is like 75° cooler than where it could be because I was racing at an I door track in the cold Canadian winter, perks of living where the air hurts your face 👌

[@xiar5546]

I love that. My motor sits very cool since its only 50 out right now and it has a cooler on it. My esc on the other hand. Overheats in about 2 mins. Lol

[@michaeljohnson254]

Air hurts my face in airzona when its 125 degrees f 🤣😂

[@imy.antqqq]

Bro your the best rc cars KZbinr 💯👌

[@chrisclifton4609]

I actually am watching this video while at our local track. The building we run in is not temp controlled and today it just hit over 100F today outside but in the building I just temp'ed the railing that is on the drivers stand and its 116F there and 109F at track level. So I really only have 50-70 degrees to play with when before temps too high personally for me. I usually try to gear without a fan up until it got over 85F outside then I had to starting running a fan on the motor. Only part I personally hate now is that if the fan stops working I could loose a $100 motor (Could be more or less). Cooling is needed in the summer where I race....and a parka is needed in the winter......I love it

[@koolaidwaterfountainsforth4236]

I'm not a racer but a basher.. but I stumbled across the WTF (wild turbo fan) branded fans and they are some serious air pushers. A bit more expensive than a standard fan but they move no less than 3× the air. Offered in 25mm, 30mm and 40mm. Those looking into cooling fans I highly recommend the WTF brand. Tried one myself and now gonna be replacing all my other fans with that brand. On my 8th buggy just a 40mm WTF fan on 6v on a fan mount dropped my motor temps 30°F. Ebay is where I found them easily.

[@racingrivals8934]

When i first plug in that fan i said wtf never seen a fan that powerful

[@henryyip8478]

koolaid water fountains for the fat kids Yes, WTF is very power, and it support 8.4v, so you can connect battery straightly

[@nathandavies2677]

Thanks!

[@jordonpollock1550]

Bit late but I just got a good deal on a TLR 22 5.0 with a brushed motor and one of these WTF fans in it.. putting a hobbywing combo in it this week, but keeping the fan now!

[@EchoS1x]

Very informative video! Many probably don’t or just plainly forget about how heat differs during different outside temps and track conditions. I live in Wisconsin so it is basically freezing 8 months out of the year.

[@claybock8998]

Liked your video, trying to get back into RC and just gathering info. Thanks!

[@mtman2699]

When I was racing in the summer in Nevada. Once we were off the track we had small desk fans blowing on the electronics to help keep them cool between races and practice times to help keep the temp down.

[@IANBEARZ]

Best video on temp control ever made!🔨🔨

[@jesseortega8598]

Awesome Info! I have Both ! An ESC fan and a Motor fan! And I'm way ahead on the whole body venting idea! That's exactly what everyone needs to do to keep their vehicle as cool as possible!

[@dosilecreations6229]

In oval racing we disable thermal protection. Also keep in mind after esc reaches a certain piont the esc will reduce power. But normally 150 to.170 in oval racing is acceptable.

[@denniszellers6423]

One tip i can share in regards to aftermarket fans is keep them from being too close as some rotors can actually stop the fan and cause it to fail. Learned the hard way on two different fans. Some motors it's not an issue but the stronger ones will definitely stop the fan and cause them to eat themselves.

[@ChriswithaCrc]

Hey buddy been follower now for a few weeks and been binge watching your videos as just come back in to the hobby and funny thing is I was looking for ways to keep temps down a bit better with my new brushless system as I'm happy with the speed but want to keep the temps as cool as possible . Funny thing is when I was racing years ago I used to make holes near my ESC and motor and people used to wonder what the hell I was doing . I took race car idea that if it keeps a petrol car cool that it will help with a RC . So going to give it a go as I don't like gearing down to much . Also picked up on the polishing hinge pins etc for less friction awesome tip that made suspension is miles smoother . Keep up the good work bud .

[@RcJourney318]

Hey Ryan forst things forst your the reason I got into buggy racing number two I built my body out of duck tape it’s basically got like two hood scoops like house find on a car on the top of the roof along with a fan on the esc thanks for your freal videos and I hope racing continues to make you happy

[@billbarberconstructioninc.17]

Awesome vid... I would also throw in drive train, and free moving parts... especially for beginners, if you have any drag, or resistance in the drivetrain, overheating will also occur. Keep the vids coming...

[@RyanHarrisRC]

Very true!

[@johnpenneyston8101]

Just race in the UK where it is too cold to get hot lol. Great vids buddy

[@RyanHarrisRC]

lol Lucky you!

[@mojaverc1585]

I’m australia. Motor wants to explode in 5 mins. It gets really hot

[@jiveafrica4232]

Very informative thanks! Keep up the excellent work High temperatures in South Africa can often be challenging

[@mojaverc1585]

Jive Africa hello fellow south african

[@Gavs_rc_hobbies]

With my 4wd buggy i use a low profile heatsink for a 12th scale pan car as well as a fan. Its shape helps fit under the body (this also depends on what body you use).

[@jhendren0001]

Great job thumps up,,,, keeping a close eye on temp can help find other problems as well like bearings that may start binding because it will as expected make the temps climb so if you know everything is in check that could be something to look at.. I was running a 1/10 scale 4wd truck and noticed it was getting hotter than normal it turns out it was the front differential bearings but I hadn't noticed any lack of power or anything at that point just a little spike in my motor temp.... Again thumbs up brother it's the simple things people forget to watch could save some money..

[@twain772]

I installed a brushless setup in one of my Tamiya 4WD buggies and just cuz I didn't know what the car could handle or how the system would react to the vehicle I made it where the cooling fins of the esc stuck out of the body just in case so heat wouldn't be an issue. turns out the set up was good and the cooling fins sticking out looked kinda cool so that is how I ran it. I dont know what and OG is but i remember those days. I remember where you had to keep up with your springs and your brushes if you wanted the max performance out of your vehicle. I also remember the first time i saw a brushless system. It was an article done by RC Car Action and they had 2 Avox brushless systems on a clod buster with a racing chassis. The article was good but the truck was sooooooooo sweet. When i ran my t-maxx i thought it would be cool to give it a scoop so i did so and put the breather in the scoop, using aluminum tubingto keep the air cool as it traveled to the engine.

[@alexr9030]

Good video, you forgot to mention that you need to carefully adjust your ESC (Thermal protection) when adjustable , a lot of motor thermistor do not relay good readings for motor temperature and this is why a lot of people have fake thermal shutdowns due to the motor giving the ESC a way to high temp reading . I prefer motor without temp readings but for those who has it I adjust the Thermal protection Higher and carefully monitor the outside temps of what I consider OK for ME ( not higher than 165 F )

[@richardbrown6762]

I cut cooling holes in the front and back like the nitro cars and that helps 😊

[@Channel53official]

What’s that vertical rack on the wall? That’s killer man

[@Lunarpollo5622]

Quick question Can I run a 12v 0.6A rated cooling fan on a 12.6v 12A power supply or will it smoke up?

[@yofoo138]

Thanks for this video I had my first race last night and was in a commanding lead and boom overheated 🥵 will try these tips

[@pbednar]

another good way to improve cooling of the esc is changing the stock thermal pads under heatsink with something like thermall grizzly carbonaut (be careful they say it's conductive so put it only where it should be - on the top of transistors and not just over whole pcb)

[@performancedanny]

I use a shroud helps direct air to the motor works pretty good. thumbs up and subscribed.

[@dustinspallone6659]

Wow.Whats really funny is i mounted up a new fan for my 4 wheel and went to Mills to practice today.

[@alfa7108]

Especially in this Florida heat. Good vid

[@roboman2444]

Another thing to mention are things like Aluminum motor mounts instead of plastic/carbon and/or small can heatsinks. Many years ago i kept frying Mamba motors until i threw a small can heatsink on them.

[@NordicRC]

Good vid. Would love to know what temp is recommended.

[@RyanHarrisRC]

For most of my 1/10 off road stuff I stay at or under 150

[@NordicRC]

Ryan Harris Thanks!

[@sumaanshaikh548]

@@RyanHarrisRC well i have a 4wd slash i have stock gears i will use the same esc heat sink. Will it cool down.

[@andrewnielsen4890]

When you’re running multiple fans like that how do you power them all? Run some to the receiver and then some off of a battery tap?

[@andreasjonsson8075]

Maintainance and new bearings seems to work.

[@mr.huxley8347]

For motor fans what do you suggest blowing into or away from the motor? Seems to be quite the debate.

[@shorttrackrc6976]

hi ryan so i have a older team associated sc10 sct and find it really hard to cool the motor any ideas 👍

My slash 4x4 got really hot today ! I just unplugged it let it cool down :) Better than forcing the temp to be down

[@WERONEfishing]

love your vid ryan your like my yoda of racing i'm the little cute one learning thanks bro keep um coming

[@JimmyKay1976]

Does throttle frequency create/reduce motor and ESC heat?

[@dylanchadderton1]

The Ardncraft B64 and J-Five Designs B64 fan mount/shroud are a much better solution for keeping the 13.5 wheeler cool than just sticking a fan at the back of the motor. It dropped my temperature 20-30F compared to the fan in the back, and that is exactly what they advertise. If anyone needs the link for those just ask, but a Google search will bring them up.

[@evanroethrc7386]

@Ryan Harris, Another way that I use is for 1/10th motors you can turn down the timing on the end bell of the motor can.

[@dudeshahs4282]

I thinking about getting a19 pinion gear for a xmaxx and the xmaxx has already has fans should I get more ?

[@fill596]

Hopefully you get this. I just bought a 22t 4.0. I wanted to know what electronics you would run. I can’t seem to find any good place to make a hood recommendation. I know there are slot out there. I like your set ups but can’t tell what you run. I’m just an amateur looking to have fun. I’m not into competing. Thanks man. Keep up the awesome videos

[@bryanbarcelon3701]

Outside in Colorado is prob a bit dif than where your at. The content of sand or i.e dirty soil and loose conditions are more prevalent . The outside temperature can still get high , mid 90s. So air flow holes are common in bodies but its a necessity ( in my opinion to cva glue faucet screens cut down to the inside the body to curve the amount of debris that can enter these openings

[@reelinin5509]

I was having the same prob and I thought it was the battery at first, because I don’t have a esc fan cooler but instead it has a heat sync for the esc. The people who built the kit in the factory half-fast built it, so then they put the esc in the middle of the servo and the 550 brushed motor. So since it was in the middle the heat sink wasn’t getting any air flow. So I moved the heat sink in it’s own spot to get air when driving, and it drove just fine without any problems. But I still do want to get a cooler fan for my rc.

[@biker_bez]

How do you hang your cars on the wall? Would love a what gear you have video too

[@samcrow1071]

New subscriber. Love my rcs

[@mechanicmike2858]

Great timely video good tips for hot racing

[@sammy_1_1]

I bet adding a few 3d printed air scoops could help get air into the body too

[@luizdemattos4485]

Here, in NYC, in the summer I run 2 fans on my buggies. One mionted on the waterfall, pulling hot air from the motor and other mounted on the chassis (B6s) by the timing plate, blowing fresh air to the motor. So far temperatures are pretty good. Just my two cents.

[@Andrew-hh3ol]

I think I’m under geared with the stock gear ? I usually get just as hot going fast as super slow, so do I gear up for going faster because I want to go a bit faster and keep it cooler , would gearing up help the up end speed heat? Edit: I’m mostly doing long stretches of speed

[@cjprior88]

Good video i will try some of your suggestions. A lot of them i didn't know about.

[@Zoyboy]

Good informative video!

[@MrCoops869]

I race 13.5t stock onroad in Australia and I’m lucky to have 3 tracks within an hour of me and I deviate between all 3 so I temp my motor after every run at every track, I use one tram zombie 30mm fan on the motor, normally comes off at 50 degrees celcius every run after 6 minutes

[@ginopoe9150]

I’m a nitro guy starting out in Electric, but are airscoops allowed in electric racing?

[@Roccodimauro3116]

If you go up on pinion and down on spur is that still gearing down??

[@rconly2057]

[@ShannonStathakis]

What happens if my Moter oread has a cooler but still over heats also is 4 wheel drive must I put a fan on it

[@aaronsalais3477]

I have a TLR 22-4 2.0 4WD Buggy in my 22-4 2.0 4wd I have a reedy 510R Blackbox I use the programmer 2 box that came with the 510R to turn things like the Drive frequency down and certain braking parameters up and adjust throttle settings. I run a 16t pinion with a spur that's 81t to 86t on my hobbywing mod motor and a blue heatsink that slides onto the motor, I set the timing on my mod motor at around 34 to 38. With the way my silencer body sits on the buggy awesome ventilation front to rear. The body does have pre marked spots you can ream out with a body reamer for extra air flow if needed. A heatsink on the motor geared with a 16t pinion and 81t to 86t spur and low settings in my 510R Blackbox is how I run with ventilation front to rear no problems running on a full charged 5 to 10min run on my 6300mah 7.6v 2s shorty.

[@timothyshaner8926]

So how do you know a safe gearing to start with? (May be obvious to some but I'm new...)

[@fabiofboful]

Hi, currently i'm using a surpass 2838 4500kv motor with a 35A esc with a 15t pinion and i'd like to add a fan in the esc. Is there any problem of powering that fan using a free receiver channel or it could damage any part? Thanks.

[@mepanza]

[@rygaarrygaar2878]

The video is awesome but for someone new getting back into the hobby needs to to know what should the temps be at or around after runs

[@RC-ty5ym]

Should not be higher than 90 degrees celsius.

Bought a Schelle fan mount works great

[@desert07576]

Any recommendations? Motor speed control packages? Fans ? Heats sink? Thanks in advance.

[@kylepark13]

To keep a good air flow under the body have you ever made slots/holes in the body and mounted a fan to the underside of the body?

[@yodad4776]

On a old vintage car I got from my neighbour the motor was cooked and the ESC has no heat sink with 6 MOSFETs sandwiched together ...I added a 25mm fan to the under side pushing up and mounted it on brass bars 10mm off the base and split each MOSFET just enuf so it's got a gap and glued a heat sink to the tip of them with the fan running not stop off the battery if it's plugged in. .with a used drill motor it's now insane and it's the battery getting hot now cos it's able to draw so much current now continuously so I custom made a 4p2s lion battery from 8x 18650s and now I'm thinking next time il put a 30-35mm fan in one end on a switch so when it's got heat shrink on it draws air thru the battery directly

[@bellstangrc7799]

Love these kind of videos!! So informational..helps us out here alot!:) love all the vids but I definitely appreciate these ones!! thank you sir!

[@Innvctus]

where would i plug it in? the esc or the transmitter? im gonna have to get one for a Racing Durango DESC210 and im new to rc stuff. it overheats in about 10 mins of use and i cant really take off the gears because my allen keys get stripped. Any tips what to buy and what to avoid? And what tools to buy?

[@jaesrcworld3953]

Another great video... i just got myself a used stadium truck. It’s a tlr 22t 2.0. What do u suggest on set up, gearing, and fan placement?

[@RyanHarrisRC]

Nice! I'm not very knowledgeable of the TLR stuff these days... Maybe find something in a Facebook group for TLR?

[@raffymagaling2516]

which should i put the fan on? motor or esc?

[@stevewest7260]

Another quick tip to lower your motor temps a bit in a pinch . C-clamp around your motor will also dissipate heat from the motor when there's no other options..

[@alifkhanfatihkara]

More battery cell which means higher voltage is also caused ESC overheating?

[@killian239]

Have you considered a radio that has telemetry with a temp sensor? I have one and i can set an alarm for when things get higher than a certain temp. This way i do not have to temp the motor when it comes off the track and i get real time temp info on the motor while racing/practice ?

[@RyanHarrisRC]

That may be an option for some scenarios... however not all parts of the motor are the same temp. I like to do it manually and make sure I get as much info as possible.

[@Andrew-hh3ol]

I’m using a standard voltage servo from amazon one of the 20 kg ones , brushed 2s not conservative gearing but the motor heat isn’t the issue , it’s staying about 100 degrees , would the servo cause a issue?

[@HighhScore]

I have a castle Sidewinder4 in a rock Rey stock gearing with a 1415 castle brushless motor. I have a 16t pinion and my wires are melting the solder on the esc. The bullet plugs and my wires going to my motor (I now have 12awg wiring going to my motor) and after going half throttle for a minute my bullet plugs are way too hot to touch. On 2s and 3s. What is going on here? Maybe a bad motor?

[@AdolfoSalasfrost]

Hi there, can you explain each individual setting ESCs have? Stuff like the do/don't do with your ESC programming for a specific motor and class. Also , setting interactions, like if you set the X setting to certain level then you should also change the Y setting in correspondence. I know that different brands sometimes have different names for the same setting , but it would be great if you did like a generic review. I only discovered your channel recently but I think it is great. I'm personally not into interviews but I watch your tips and setup advice over and over again. Great job !

Do you remember the muchmore racing thermal cooler fan i suggest them they make your motor ice cold to condensation starts awesome fan look um up if you have seen it i'm sure you have. much luv frm u.k

[@turtletrading4207]

Nice video but I was hoping to see what to do when we have cold motor/hot ESC/cold batteries, hot motor/cold ESC/cold batteries and so on. Personally, my ESC is getting quite hot while the batteries and the motor remain cool. I was thinking of increasing the pinion and reducing the spur teeth number by one or 2. I am not sure if this will work though. I run WTF/Racing Performer fans on my ESC and motor.

[@anythingcars1389]

I mainly do speedruns with my slash and it gets really hot so after one or two runs I just let the dual fans cool down and then run again is this okay I'm on a 25 tooth pinion for 76th spure

[@killerzweg509]

Is there a watercooling system?

[@evhexrc1765]

How much better are the Wild Turbo Fans than the others? Is it really a night and day difference?

[@superjoint57]

EvHexRC 1 They are really great (IMO) compared to others I have used. I actually think a few out there are the same exact fan...just branded differently for each company.

[@justincoontz6719]

I have a fantom 17.5 motor runs a little hot not bad. Rx-482 receiver with transponder servo esc and ya fan plugged in. Hobbywing justock esc with fan. When I put my ya fan by my motor it dies out? Am I drawing too much power or is the magnets killing the fan??

[@dominickdelfino7552]

Ok after 30 years just got back into RC. How do I wire my motor fan? Does it go to speed controller +/- or does it go to receiver and what port in receiver?

[@KusshLover323]

It goes plugged in to the reciever and it goes into por # 4

[@ten2doyle415]

Good info here. Funny, last race day my 13.5 motor randomly started getting hot in my new XB4... normally comes off after a 5 min run at 140 degs....suddenly hit 210deg. no changes, same track as well.... I also used to be able to run consistently for an entire battery pack without overheating. Still haven't figured out what happened yet though. The car rolls smooth, no drag from what I can see either. Kind of a bummer though cause that ain't good for the motor.
