e254: Ampro Working Traxxas UDR Rear Fans

[@aviano72]

This was not pointless at all :) I've always thought when i saw these types of trucks how cool it would be with real fans instead of just plastic.

[@AMPROEngineering]

Same here!

[@treyfixes884]

We’ve all spent more time and effort doing a lot less awesome things for the same reasons you did this. It’s spectacular and I love it hah.

[@AMPROEngineering]

That's the truth! Thank you very much!

[@drog343]

Exactly, 😁👍

[@rupsingh8516]

Ppp

[@Gridnack]

Thanks for making the fans functional, I'm in the process of making an fpv setup for mine and I'm using this fan plate to blow air onto the vtx.

[@AMPROEngineering]

Perfect! It was just begging for the mod.

[@TurunRCkerho]

wow it had "fans" as stock :o that's some crazy detail. And your mod is on a another level! stay safe and keep up the good work 👍🏻

[@AMPROEngineering]

Thank you so much. You stay safe too...we are in some weird times right now.

[@Openthrottlerc]

@@AMPROEngineering where can i buy this?

[@LuisLPRCs]

I'm surprised RC Companies have not made working fans for the UDR. Great Vid! 👍👍👍👍👍👍👍

[@AMPROEngineering]

I agree! Thank you!

[@larrytemen4789]

Soon as I get paid, I’m 1000 percent buying one. I hope you still make it even though it’s been 2 years since you uploaded this video.

[@AMPROEngineering]

Oh yea, it is at MyMiniFactory and shapeways. Links in description. Hit me up at [e-mail] if you have any questions.

[@MrJoe478]

Wasn't pointless at all. I really enjoyed the video. I feel the same way and wondered if the UDR fans worked from factory.i don't have one so seeing this video caused me to buy the fan assembly so I can do something similar for the Mojave EXB roller I'm going to purchase soon. To purchase the back shroud from the site is kind of pricey so I may just buy 2 tornado fans and leave the back open for the meantime. Thanks for the idea, I 👍🏼, liked plus subscribed.

[@AMPROEngineering]

Thanks Joseph. I know its not really needed but I just thought it would be cool!

[@normandykush3134]

That light up blue !! Bad ass

[@AMPROEngineering]

I know, cool right!

[@VikingDudee]

I've done this before when I geared my slash for speed, although my aftermarket receiver had a aux port where I connected the fan and was able to turn it off and on with the remote, was neat, and it did work rather well.

[@AMPROEngineering]

Oh I like that!

[@AngryDavesADULTRC]

Awesome detail man. It's never pointless if it's cool. -"Angry" Dave

[@AMPROEngineering]

Thank you! I was just watching your Axial SCX10 II F100 unboxing last night. I needed some on mine and that did the trick.

[@normandykush3134]

About time ! Some ones made that fan to work with duct!! The important part :):)

[@AMPROEngineering]

Yeah i mean i know it doesnt do much but I wanted it to do something!

[@TheRCGenius]

I love doing these kinds of DIY stuff with RC's! This was awesome to watch, I don't have a UDR yet, but when I do, I will be doing this! Just subscribed, I look forward to more on your channel ;)

[@rccosplay3249]

You're going to enjoy it! Awesome scale machine that should IMHO be driven scale with mild bashing, plenty of jumping and doughnuts galore! It performs best in sand/dirt. Due to the solid rear axle on grass especially wet grass it might tumble and flip a bit... I love it😁 Make sure to open ALL the Diffs and transmission to clean out and fill the cups with appropriate oil and grease all the gears and axles. I do this 3 times a year👍

[@AMPROEngineering]

Thank you so much. I know they don't actually do much but the whole concept of them being operational is what I was concerned about.

[@edwardlove4300]

Happy to hear you laugh. COOL project indeed!

[@AMPROEngineering]

Hah thanks! It was fun.

[@matthewroyce7315]

Awesome. Would've been nice to see actual footage of it up and running with everything reinstalled at dusk

[@AMPROEngineering]

I will soon! I dont think I had the body done when i filmed this.

[@AdamAlistair]

I ordered this from you, and the other parts from amazon before the video ended! Can't wait to see if I can make this work :)

[@AMPROEngineering]

It is a pretty simple build. I wouldn't say it helps with cooling but it looks awesome! hahah!

[@AdamAlistair]

@@AMPROEngineering I'm more into how cool it looks. Every time I see a non functional scale accessory like that it bugs me that it's fake. This is great! I might do the head/taillights too. The price is worth it for such custom stuff. Thank you!

[@AMPROEngineering]

@@AdamAlistair I feel the same way! I cant recall the price, it really depends on your country and material selection.

[@mikesteck1310]

So great! I am a detail freak and I want to eventually make the machine as detailed as possible. Where might a pre-fabricated part be available for those of us without a 3D printer setup?

[@AMPROEngineering]

YES! There is a link in the description but last week I made a change to make the part less expensive and its getting approved. Give it a couple days.

"Pointless", and that's precisely the point to doing it...making it your own...back in the day(20yrs ago) before 3d printers, we used to hand fab all kinds of things, "pointless" as they may have been, they were really cool, as this is...kudos...

[@AMPROEngineering]

I agree with that. Pointless stuff is some of the best stuff

[@hemitj]

Love it! Totally awesome idea! Can't wait to do this to mine!

[@luisgvierna]

Smooth job, cool video. Keep it up!

[@AMPROEngineering]

Will do!

[@littleraptor9898]

what i did is added a second water cooler right there, and one smaller one in the front aswel. i wired the water system like: reservoir-front cooler-electronics-rear cooler-reservoir again. i initially wanted to make it to go to the ESC from the front one, then to the rear one and from there to the motor, but that would be less effective.

That is a good idea!

[@DylanLehman-j6z]

Hey would it be possible for you to extend the cooling ducked down to the motor if I were to cut a hole in plastic above it

[@AMPROEngineering]

yes in theory but there would be a lot more losses in a longer duct and likely not push enough air to really help.

[@N_Fortune]

Love your attention to detail! I'm planning to tap the ESC for power but for using the Traxxas OBA (On-Board Audio) on my UDR. I did this for my Slash ESC that didn't have OBA & it worked GREAT! BUT if I did this for my UDR & I use the UDR Jumper Connector (single 6S lipo), then can I simply solder to the black & red wires of the 1st lipo port? Since the 2nd lipo port has the jumper connector plugged in, right?

[@AMPROEngineering]

Well if you use the 1st port, wouldnt that only give you 3.7v? Super sorry man, i dont think im following you. email me at [e-mail]

[@N_Fortune]

@@AMPROEngineering I just sent you an email, thx!

[@alexfuhrman5131]

Regarding the product link, if I buy it, will it include the voltage converter thingy? And If so, is it already adjusted for 12v? Very cool mod btw!

[@AMPROEngineering]

Alex, this is only for the printed part. Everything else is sourced on ebay. I used to have links but as is with ebay, the sellers all change. Glad you like it!

[@newelementfilms]

I wonder how much quicker the battery drains having those fans going while driving around.

[@AMPROEngineering]

They dont draw much at all but I suspect a bit.

[@富贵-r5f]

聪明动手能力强值得学习

[@AMPROEngineering]

谢谢！

[@2424gold]

Could the fans be powered by a ubec, connected to the batteries the same way as you did?

[@AMPROEngineering]

I dont see why not. As long as the fans dont draw too much.

[@conair1850]

could i just run the fan wires into a plug and plug it into the reciver in the reciver box

[@AMPROEngineering]

I replied to your other post but here you go in case "Well, the voltage on most receivers isn't high enough usually. On top of that, that could be a bit too much current. Safely, I would say no."

[@itsmigz5593]

I just ordered my UDR should be here in two weeks, how can I order this? Badass man!!!!

[@AMPROEngineering]

Thanks! That's what's important!

[@barrysrcdump3557]

AMPRO Engineering I was in CNC engineering for 35 years, so I know what goes into making your own parts. Anyone can throw a battery in it and bash away, I think it’s great that your making it “Yours”. 😁

[@TheAmericanUhate]

Isn't the ESC fan blowing outwards/up from the ESC? Like it's pushing the heat away. Shouldn't those fans be pulling the hot air away from the ESC and blowing it out the back?

[@AMPROEngineering]

The fans are blowing into the ESC since the ESC fan is blowing into the ESC. On the real car, yes, that is how they work but the Traxxas already has a fan so these simply help. If the pulled heat out, they would counteract the factory esc fan.

[@loicsabourin3759]

wouldnt the dust fly directly inside the ESC?

[@AMPROEngineering]

There is already a suction fan on the esc. These wont add much to it.

[@justinjohnson792]

Why didn’t you hook the voltage regulator up to the output from the receiver you could just plug it in and you didn’t have to do any soldering This wasn’t a useless video this is something I would do

[@AMPROEngineering]

That's a great question. The reason I didn't i was that i was not sure what else I would run off of the receiver . I know I will have at least two sets of lights, maybe more, so then I didn't want to pull too much current from it. Perhaps it wouldn't have mattered? This was at least a safe spot to get access to power.

[@nomusicrc]

AMPRO Engineering I have one rc with 30 led lights in it so I know that doesn’t matter

[@TheAmericanUhate]

@@nomusicrc led's take very little power of amperage to run them. Not the same as fans, which takes a bit more than led's.

[@nomusicrc]

TheAmericanUhate I know this you can still put a bunch of led’s on one channel and a fan on another that’s what I do each fan has its own channel

[@Hirthirthirt]

That is neat ....but the LED's are cheesy....and you should suck the hot air out...not push in.....

Well I wanted to suck air out but the ESC fan right there sucks in so I had to push it. Yeah the LED's are silly for sure.

A larger scoop at the end near ESC would work better if the fans were drawing the air up and the fans sucked. seeing as heat rises.
