How to Fix R/C Fan Problems + Pinion Weights - B6.2 Build Series Part 5

[@j-chriswall]

We've used the factory side rail mount and just added a couple vent holes in the side of the body for inlet. That keeps it away from the drive line and gunk that can get thrown in the fan blades. Moving the fan to the end of the motor bell also shifts the magnetic area. Have had no problem with magnetic pulsing in our three cars racing stock 17.5 with Maclan V2 motors.

[@EK-np4nx]

It was around 90F in Georgia a few days ago when I got out to drive my rusty. Came back inside 2 minutes later after the motor over heated. I can’t imagine how hot it would feel there. Stay cool!

[@AMain_Hobbies]

Thanks, you too! -Brett

[@kg5nja693]

Loved the video from the buggy. You do want the heaver oil in the front shocks bc lighter oil lets the front tires bounce and the heaver oil stops that so you will have better control of your steering. And the lighter oil in the rear helps with traction by letting the rear squat faster.

[@jcchaconjr]

That's it - that FPV makes me want to drive down the straight all the way to the wall even more! But the layout in the aerial shot at 6:43 DID have the straight going all the way to the wall. Someone is conspiring to suck the fun out of the funnest part of the track... 🤔 Haha! I love this series, Brett. Who knew that the motor would be the culprit of what many might just write-off as a bad fan? I'm just returning to the hobby after a good long while - my motors had brushes the last time I ran , so that little fan issue certainly would have thrown me for a loop.

[@AMain_Hobbies]

Ha. No conspiracies here! That aerial shot is older but still a great shot of the facility. We had issues keeping the GoPro upright on the buggy and not tilting down after landing jumps. There were a few shots of the wall ride but the view was down and not great. For the fan, you are very right. Many people have complained their fan was bad when it was just too close to the motor. Then they buy a new fan but the issue repeats. Have fun with the hobby. Brushless, LiPo's and 2.4GHz has improved it so much. And those brushed motors are still around! Let me know if you need anything. -Brett

[@jcchaconjr]

AMain Hobbies Oh yeah , no more crystals nor chasing down clothes pins with your channel number on it - best part of current tech in the hobby by far!

[@tomkirbygreen]

Good to hear from you again sir.

[@mgers75]

good info on Neodymium temp threshold. My concern is if I temp my motor after run and its 150 or so degrees. The magnet that's deep inside is much hotter . Sounds like we need more cooling.

[@RACEABLE]

until now :entertaining videos! from now on: scientific approach.. that’s why i like your style!always something new!! keep the good work mate!

He's a high level driver I'm pretty sure. I saw him racing, he's good.

[@innovativerc7155]

Awesome Video, as usual!! I liked the onboard footage. Well done for solving the problem with the fan. 👍👊😎

[@brianbeck7468]

That looks like a really fun track. If I ever find myself in Chico, I’ll have to stop by.

[@AMain_Hobbies]

You definitely should. We have the 1/10 carpet track, dirt oval and 1/8 dirt track. -Brett

LOL you caught that too! I love that they really don't take stuff out of these vids... well, that we know. lol

[@Jeroen-Engelgeer]

I've learned something, very good. Now i know what causes the strange behaviour of my fan.

[@emanuel616]

Damn dude you can drive 👍

[@lukas21614]

You should try the "Schumacher Cut Staggers" for the front, you will get way more of power steering.

Great video show brother. Thank for sharing

Thank you for sharing this video now i know what going to do with my fan

[@fcsthememe7987]

I'm not having that issue at all oddly enough so far. I now realize I need a temp gun, but Amain doesn't contain a solid one. The protek one looks iffy especially considering the negative reviews. Oh well Home Depot has a better affordable one. 35 bucks and comes with holster bat and charger drop proof I'm set.

[@thomasgross8289]

I was about to say a industrial use temp gun would have to be cheaper than a "RC heat gun " slapping RC on the name of something has to be one of the biggest cons in RC lol

[@austinhomer8545]

few things to maybe look into, different diff fluids (thicker or thinner), maybe look into a front wing to try

[@lakarevardebro3338]

You'd better tune your motor to run less hot. Especially when you run in a 40c environment. A fan is a good solution for extra performance, but not to initially bring the temps down.

[@mulletaquaticlife9335]

After this series can u do one just like it but nitro

[@joracer1]

Good deal. I always run mod, motor temps are not really a problem. But in case I go to Texas to race I might need a fan. Where did you learn to paint those bodies like that?

[@arcadiavfx]

Awesome build Rc car

If yall could make a slash 2wd to 4wd conversion that would be cool

Great video bro keep up the good work

[@jamesdriesen7669]

can you do a upgrade series over the RB10 like the build serie you have here

[@DjghostyMusic]

that track is a dream 😍😍😍😍😍😭😭😭😭😭

[@BOOGiNS]

I have juststock components in mine. With a 30t and 69t. It runs 120degrees after 10minutes. Kept my fan in the right spot and just reamed some holes in the body. She's silent as a whisper. And runs very cold.

[@joshuajkoplin]

I run canola oil in the front and olive oil in the rears.

[@joeyfesta2042]

Brett,,I live in Florida,our ambient temps are 95-103..Motor temps are around 200..What cooling fan do you recommend for the 3660 in the Arrma Big Rock 3s BLX.? Price is of no issue.Something a little overkill I’m 🤔 thinking.

[@AMain_Hobbies]

I don't think the factory heatsink included with your truck has a fan mount, so I'd replace that with a proper fan mount and then go with the ProTek fan. There are tons of mounts available, that will hold one or two fans. If you go with a two fan mount, you'll probably need a Y-Splitter because your receiver probably doesn't have two extra ports available, but most likely has one to plug the fan in. Any 540/550 motor size mount will work (36mm diameter). Here is what we have: www.amainhobbies.com/fans-heatsinks-electric-motor-parts-electronics-cars-trucks/c2973 Here is the ProTek Fan: www.amainhobbies.com/protek-rc-30x30x10mm-aluminum-high-speed-hv-cooling-fan-silver-black-ptk-2111/p995313 -Brett

[@waynerc2420]

Buggy seems easy to drive now and temps are down

[@skagerstrom]

Wonder how that fan would feel like going a few laps on a gravel track :D

[@rcforlife553]

it was only my protek fan that had this issue. i switched to the yeah racing fan and it never had this issue again

[@vrooom666]

I really miss rc racing. i sold my PR S1 and is looking for AE b6.2 not sure if i should wait until b7.

[@AMain_Hobbies]

You can pick up some nice used B6.2 buggies to hold you over. We haven't heard anything about a B7 but you never know when. -Brett

[@413RC]

How are you keeping your GoPro on the car? My mounts seem to come off on landings

[@AMain_Hobbies]

When you buy a GoPro, inside the box it's mounted on a base plate that is big and square. We drilled holes in that and the wing, and mounted it with M3 screws, washers and locknuts. The camera kept tilting down after landing hard though, so it's not 100% great solution, but we were able to get a few good laps with it. -Brett

[@Krideezy]

Guess I wasn't subscribed.... WHOOPS. I am now :D

[@CarlosDelaoGunEngraver]

What camera did you use for the onboad footage?

[@AMain_Hobbies]

It's a GoPro attached to the rear wing. -Brett

[@jonwolery9800]

Curious, how did you wire up the fan? Looks like it goes under the waterfall... direct to ESC?

[@AMain_Hobbies]

Yes, the wire runs under the waterfall, under the battery and then plugs into the aux port of the receiver. -Brett

[@HL-OOI]

B6.4 has a fan mount now..😂

[@xxmistasteffxx5940]

Can u do some upgrades for a benzin rc car?? Plz

[@darkraiden]

what camera was used on the RC I feel like a go pro would be too heavy

[@AMain_Hobbies]

It was a GoPro Hero8 Black screwed to the wing. It did not work well. After landing each jump, the camera wanted to tilt down, and slowly did. -Brett

[@byzone0632]

Im looking to buy a 2wd drive buggy I just sold my 2018 xb2 because I didn't feel like it fit my driving style anymore and I have been watching these videos trying to decide if I want the b6.2, though the only thing shying me away is that I wasn't really impressed with my B6 is this B6.2 a lot different or should I expect the same the same car with some minor changes here or there. Thanks!

[@AMain_Hobbies]

The new cars have a lot of updates to them. I didn't use the original B6 so I can't speak too much towards it, but the new cars are quite good. Just be sure to choose the correct car (B6.2 or B6.2D) to match your usage to save a lot of hassle down the road. -Brett

Hi

[@JFlyer1973]

Brett, I have a really good and very important suggestion for this buggy... now this is important... it should be donated to an aspiring buggy racer to promote the hobby and good will and sent to my home address please. I can email my address when you are ready. 😉 😁 Jimmy

[@mikejurnak0324]

🛑Amain can you help nobody can answer Can you put a Fan on the ESC of a ARRMA voltage?

[@AMain_Hobbies]

It looks like the ESC in the Voltage vehicles do not have an integrated fan mount. You could fabricate some sort of mount to house a fan, maybe something out of plastic or lexan, and perhaps screw it down to the existing screws that secure the ESC? However you do it, you'll need to create something custom. You would also need to ensure your receiver has one extra port to plug the fan in for power. Hope this helped. -Brett

[@geraldsweet8047]

How can i get that mount?

[@AMain_Hobbies]

The gopro mount is a regular mount we screwed to the wing with screw, washers and locknuts; you can't buy it, you'll have to make it. -Brett
