This is the full video from a few days ago hope you enjoy :)

Kevin: alright guys do you wanna make some ext- Me: SKIIIIIPPPP

I think this truck would suit 8s from factory

Awesome job with the mod! Can’t wait to see it flat out.

Hi Kevin 🤓! I was looking into building an 8S UDR and guess who popped up 😎! I'm going to scratch build my UDR and make it 8S. I'm just three years behind you 🤓! So I'm starting with the main chassis and building it my way. I'll keep you posted on my progress. Ron Young 🤓

Technically 7s? 😂

Can't wait to see it on 8s!

Hot glue and duct can accomplish almost anything! Such a cool upgrade Kev!!

Dude I love your vids,very informative,thank you for taking the time to explain things, patiently awaiting more input

That is going to be a beast on 8S! Can't wait to see it run.

Yesssss. 8s UDR. Can't wait to see it running properly. 👍

Kevin, did you do a video on how much faster the UDR is on 8s on the outside? I am sure curious how much faster you made it!

I’ve been waiting for this video for ever great video kev

Hey Kev awesome video! I have a question what gearing are you running on your trx4? I just put a mamba x system in mine but it don’t seem as fast.

hey, that was pretty cool! liked the sudden explosions! just wondering: does the Traxxas VXL-3s ESC fit on the TRX-4 using screw holes without modification? you should have one laying around from the Slash 4x4 when it came out of the box. help!

This video is crazy but I waited all day for it

Lipo: you will never get rid of me Kev: grabs a bigger hammer😂

I think the cut aways of the Unscrewing of the body is really cool I like how you put the time into it to place the camera I know it it is a little bit of extra work but I do appreciate it because it does end up having a cool effect at the end so yeah either having a music cut away with like a fast forward would do the trick

Li-po vs Kev was a good fight😄😄. I'd love to see your traxxas outdoors..

Sick vid! do u find gunning ity on polished concrete glazes your tyres?

love all your videos. your one brave dude popping those lipos like that! lol sure did love watching it though

Luv the vids Kev especially the lipo fire

Nice one get the slash back out. After watching your vids I have bought one and love it.

A receiver that supports binding to many models might be a really good investment for you. For example, Spektrum DX5C. The 2-channel receivers are like 16 bucks so it's not hard to switch all your stuff

cant wait to see wit 2 good 4SSSSS

Have you considered wrapping the center of the tire in heavy fishing line to keep them from ballooning? I think they are already fairly skinny tires so if they balloon much at all it's probably going to be uncontrollable.

Kev your videos are great. Keep it up 🤘🤘

I did enjoy the video. And you were correct alittle grinding is all the connector restraint bracket needs to accept the XT90’s

Can't wait to see this thing truly ripping on 8s

Love the videos bro keep the good work up

Great video love the lipo fire 🔥

Awesome, I can't wait to see it go

Awesome job blowing up the battery lol oh nice 7s Lipo run lol

Awesome thanks for the educated, entertaining adventures!!!

Theres another video where a guy tried 8s seems the tires are not up to the task. Can't wait to see what you do with it. Love your Videos keep em coming

Removing the body shell looks like a real crawler👍👍

10:49 I died

How much did the tiers balloon? and do they do so more then other RC?

I learn new things in your videos thanks bro!!!!!

I wish I had one of these! Dope video

That truck is awesome

I stayed up until midnight to watch this video!

Cool man know your udr is going too be crazy fast👍👍👍😎😎😎😁😁😁

Nice ! Did you Find two 4s lipos that will fit to run 8s?

Did I just see a demon be released at 12:39. I mean dat noise though got me trippin!😂

Hi Kevin just watched you 8s udr video and seen that you disposed of that lipo and was wondering if you had an old brushless motor and esc as I am trying to upgrade my latest project but have run out of money as I am only 14 and love the hobby thank you for posting videos keep up the hard work

Demolition man of RC!!

Awesome truck!!!

Air resistance will affect top speed. I suspect the vehicle will flip before you hit 70mph as the wind gets under it. May have to put stiffer suspension in the rear and add weight to the front.

Nice job Kev 😃

just got my first hobby grade rc......1:10 ecx torment sct and after the 4th run the 2wd diff went....any good reasonable brushless system and gears to use?

Hey Kevin! at 0:08 Look at the box can you see a green short course car? i have it can you make avideo with it? Thx

Exocaged rc just beat you to it :) you're still one of the first though. I'll be making mine 8s when I get it too.

Hey I just put that same ESC on my UDR. Do I have to do any other calibration so I won’t run my lipos all the way down. I did the normal calibration on it.

Is there a kit to customize those duel fans to actually work? I so want that for my 🚚!

Actually it can pull wheelies on 6s, and I have done it on 2 3s 5000mah 55c batteries, except you need to do it on a ground that will give it very good grip.

Cant wait! Kev you had your UDR placed on top of wltoys vortex box, is that yours? If so.. That little thing is AWESOME! You should totally run it once!

Awesome vid kev. That thing is gonna scream on 8s.

I'm really waiting for the skate park bashing video😢

Nice job kev

I've seen an 8s UDR on KZfaq already. I made my E revo 2.0 8s already as well! :D

Loving it man!

man Kev we'd have so much fun bashN n buildN together another great vid keep it up[ Man

Also, I totally approve of your Lipo disposal procedure.

The udr,xmaxx and the e Revo are my favorite

Don't know about you Kev, but I find my cars save me a lot of money on petrol for the lawn mower. Looking at the grass falling from the UDR, looks like you're also reaping the benefits!

Nice car and firework😉

I'm thinking of switching out the vxl 6s with a 8s and the motor with a leopard 4282 1600kv and max gear it 34/47

What are the best battery's to use in the UDR I have one I run x2 3s 5200 50c and that get so hot I cud cook a egg on them

Wow I was waiting for this video Kevin thanks I have 3 traxxas and 5 (x maxx) and 1 grave digger 😜

Kev quick question Can you do a video on fixing a broken rc car part?

it is insane on 8s and i loved th lipo fire

8s for the win

Did you maneged to save the connectors of the dead battery?

kevin have you ever built a home made rc roll cage for a slash ??if you have can't find a video

Man what you think is better that udr or e revo . me i love the desert racers

I have a few traxxas 2s lipo Will it blow up what should i do go protect myself?

What happened!!!!! Lol you trip me out man love watching your videos!!!!!

Definitely a mad scientist!!! 😂😂😂

Great vid as usual 👍👍

My local hobby shop doesn't have a floureon 3s 8000mah like u suggested what else is a long lasting 3s lipo btw loved the vid kev as usual lol

Hi there I love the video what 4 sell are you using to get 8sell power hope someone can help

Happy Days - 8S -Stay Awesome

Awesome stuff!

What mm are those motor wire end tips for hobbywing max6 esc?

so cool you are my favorite youtuber

Does the udr motor get too heated with 8s? I know max6 is fine but what about the motor?

8s has already been done. Can't put all the power down without changing some things. Mainly stiffening the truck up

What made the battery go anyways? Was it just bad to begin with?

What drill bit things to take those small screws out?

What is the full set up on this. Lipo? Motor? Esc?

Hey Kevin great video

Awesome video

8s baby!!!!

Yes you are the first one to make the 8s udr

So, I am aware this is an OLD video...but, will this be getting the IC5 treatment as well?

watch motor temp may over heat or burn up may have to use 1/5 scale motor

Love to see a drag slash Kevin

No tire wobble....did you balance them?

That was awesome
