Tip: if you used the shims inside the diff.you don t need to. Everything will be too tight. Only the blue seals. And also those metallic parts holding the cross pins inside the diff house,you should use the ones from the "non metallic" diff house. Not the ones from the metallic diff house. Try this,and believe me will not fail.
"6s in an open field looks SO slow!".. umm, what?!
If you drive your cars the way you drive your rc it is a pretty clear answer...Il☝️
Thanks for sharing this, it helps me with making decisions on my UDR n know what n what not to do
I just did my rear differential this morning. Shocking I didn't find any dirt inside. I put in a good amount of grease inside hollow tube sections and inside the diff itself. I used some simple silicon sealant I bought from Home Depot in a good size tube to help keep all the dirt out. I tested my truck and seem to get a performance boost out of it even getting 2 wheels up off the ground. I didn't have the body cover on because I shoo goo'd the shell to make it stronger. I hope you have better success keeping the dirt out of your diff! 😏
Had mine for years. Just put grease inside. Never an issue
I really wanted to get a udr but I don't think I'm gonna pay that kind of money if the diffs aren't sealed enough to keep SAND out!
thats becoming the #1 issue with this truck, can't keep the sand out
Hopefully, when they release an 8s version (like the XMaxx), the diffs will be better. Thanks for showing us what can happen with the current vehicle.
keep in mind it does not come with a rear diff, it comes with the spool like I show in the end, the diff was my idea to put in using parts that make the conversion happen. For this truck the rear spool is stock and is the best way to keep it.
What are you doing to try an stop the sand? Can you tell if the point of entry is where the third member half's go together, where the third member plugs into the axel housing, or in through the axel ends? Noticed a vid showing the bottom of the front diff housing has the a arm attachment pins running through them... I will definitely be using RTV there and prolly at all points of juncture on the rear end... Surely we can seal it up...
Ok wow. I normally really hate the intros to RC channels..but your is just so badass
Lesson learned I hope. I can't wait for the UDR 2.0. 😂😅👍👊😎💪
yep! I'll keep the spool in there from now on
You obviously have a lot of disposable income the way you slam it up the side of that mound of rocks. KUDOS
LoL not really.
I don’t know if I want to try it after watching this. Thanks for the info.
A big question what kind of diff case at that ? Look like the arrma diff gears not that the UDR planetary gears so.. what's is the complaint about it?
You should make a metal roll cage just for the UDR at that scale 1/7 or PRO scale
Im thinking about doing that I have the steel and the welder all i need is the car
Cant wait for my aluminium. housing 2 come it I was told it helps 2 keep the sand dirt out and 2 put some good gresses in side both back holes of the housing were the axial gose into fill it up I love useing udder butter rc gresses keep up the good vids see u on the udr fb page :) btw what a good way 2 clean all the dirt and grease out I was told simple green would work but figger all ask u
Urd is just too darn top heavy. Take those 2 spare tires off. And chop the top roll cage off will help it handle better and not flip on every 5mph turn.
Cool video awesome bashing drive it to break it build it to take it.
When you use a 2s added to your 6s are they same mah to work ive used 2 of the same exact battery not a 6s with a 2s i will be running my udr on 8s with tp motor
if they are the same then yeah they'll work fine, mine weren't the same so I didn't even attempt to run them all the way down.
I love the videos and you wonder why they stay broke all the time
LoL well someone had to test these things.
Thanks for the update and Information in description ... Lots of Power in your UDR what size lipo are you using?.. Having Fun RCing Laughing and Playing ✌️😎 👍
5000mah Gens Ace 6s
Take the sway bars off it's much more stable in the high speed turns trust me and try it
I made my own rear swaybar out of 1/8” treated steel and removed the front. I like how it handles now.
@@ExocagedRC ya my front sway bar broke and I drove it like that a few times then took the back off it handles so much better
UDR = Upside Down Racer!
Is that locker in replacement of that broken rear diff? Only one of my rear tires seemed to stop spinning.. I’m thinking the diff took a crap like that.. is there a link to that upgraded locker?
So I know this isn't really the place to ask questions but I would like to know how to figure out if my difs for my 4wd trophy truck is wrong
If your going to bash a scale RC trophy truck and want reliability, it has to be either the Losi Baja Rey raptor 1/10 or the Super Baja Rey 1/6 scale if you like em Big😱🤣
2:36 Sick
So why did they fail to begin with...? Where you running them on 8s and just over torqued it? Could the parts have just been faulty, ie not heat treated well..? Did you leave out the shims that we're supposedly "ok" to do so...? If one of the shafts wasn't heat treated properly it would've caused the other to go... Hadn't had any front diff probs so it's either a metal casing/misaligned problem or it's inherent to the rear axel design differences... I have all those parts hadn't installed a thing yet .. Waiting on the GPM order and I'm gonna run the spool first anyways just to feel it.... Why did you want it, was it for the rollover problem? I think that can be solved with a little preload on the shocks and a much stiffer sway bar .. We touched on that briefly; you learn anything else there? I'm full of questions lol... I'll have more to contribute in about a week once I get the parts and some run time... FyI Amazon floureon 4s 5500 35c times two fits perfectly in the stock battery box with a little finagling... Got the TP lol it's twice what came in it 9000 peak watts that's 12.6 horsepower, ish... LMAO!!
Yeah I doubt I’ll get all those answered. But the shins didn’t fit in the cup, as in they were way too thick so I left them out and it was still tight. The center pins broke and if you listen closely you can hear the skip at one point in the video. I wanted to try it for better handling and to make it more raceable and it did fine on the track but it just didn’t survive. I’ll keep the spool in the back. Yeah TP motors are super strong. I’ve got a swaybar in the back with 1/8” stainless but it holds memory too much. I’ve got spring steel ordered to build it right. You should join the new group I made. There is a link in the description for that.
I did already... :)
Clearly you don't know how to keep it from breaking 😂
Hello, Which type/brand of Red grease do you use on the gears..??
Thanks
I use Dynalube RC grease, there is a link to that in the description
Rear diff ? I thought it was a rigid axle
It is an option Traxxas offers
Yeah it’s an option you can put together for relatively cheap, but after this I’ll never try it again. LoL.
i lol with the subtitle on man those autogenerated are degenerates lol
cheers good to know!
LoL I haven't seen the subtitles are they that bad?
@@ExocagedRC they used "dick" instead of diff lol
Bro why are you complaining, people wish to have this stuff. Also your the one who drove it in the freaking sand.
Again! Lol another broken udr vid!
😀😀😀😀

We’ve taken the rear tires off and it really messes up the balance of the truck. Me and a buddy are testing a new 1/8” swaybar for the rear that’s doing really good so far.
@@ExocagedRC that would be be cool to come out with some sway bars or something, it seems like all Traxxas trophy truck model have a flipping problem but the 10th scale's have solutions like sway/roll bars and the LGC chassis for the 2wd.
