Codyboy's Unlimited Desert Racer I had this almost done and lost everything, so here goes again. I don't see a lot of interest with this, but a couple friends asked that I take the time to do it. I bought the UDR a few weeks ago when Ebay had their last 15% off sale, saved $100 dollars. It has been in my sights since they first came out last year. I research for a couple weeks on large scale trucks and MT and had a few in my basket, but just couldn't decide. Nate wanted me to get XMAXX but that thing seemed so darn big. Almost bought a couple different Losi 1/6 scales. I finally decided I wanted something with IFS and the UDR was closer to 1/7 scale over the 1/6 and close to 1/5 scale losi rock racers. Here is my parts list so far: 3 HR alum diff cups Hardened steel center drive slider Vitavon CNC alum rear axle housing Alum rear trail arms XT90 wire connectors HR heavy duty knuckles with up sized bearings HR rear axle lockouts HR fixed link steering arm Castle Mamba Monster X ESC RPM front skid plate Holmes Hobbies HV500v2 servo 55t spur gear 25t pinion A bottle of 100,000 WT diff fluid (front and rear) A bottle of 1 Million WT diff fluid (center) Rear open diff kit 2 Sets of alum brake rotor/17mm hexes Next on the list will be some more aggressive tires. Did I mention that I kind of wanted to make a few small changes to be able to play on some rocks! "thumbsup" Now I'll go see if I can get some PICS. I want to submit this before I lose it again!:mrgreen: Since we don't have a large size RC site anymore I wasn't sure where to put this so sorry if it bothers anyone being here. It is one of the most "scaled, detailed RTRs I've ever purchased. So, no unboxing, you can see all of those you want on YOUTUBE. https://oi1264.photobucket.com/album...1-IMG_1252.jpg Parts so far. https://oi1264.photobucket.com/album...4-IMG_1264.jpg https://oi1264.photobucket.com/album...6-IMG_1270.jpg https://oi1264.photobucket.com/album...7-IMG_1271.jpg Its new home. https://oi1264.photobucket.com/album...2-IMG_1253.jpg Tons of travel, even with limiting straps. https://oi1264.photobucket.com/album...3-IMG_1255.jpg Maybe a little more later if anyone is interested.

Re: Codyboy's Unlimited Desert Racer Nice! I like the UDR. I wonder if Traxxas would make a smaller sized version. |
Re: Codyboy's Unlimited Desert Racer Looking forward to watching the progression. |
Re: Codyboy's Unlimited Desert Racer im curious as to why you got the open rear diff kit? |
Re: Codyboy's Unlimited Desert Racer Dang that looks good Ernie, impressive list of parts too! X-Maxx is a ton of fun and knock on wood havent' broken much even with big jumps. I've been watching Traxxas UDR videos lately and Kevin Talbot does some crazy stuff....must resist another truck. Love the super detail and up-sized dimensions on the UDR, I think the open rear diff will make it handle even better and it's like a Slash on steroids with great scale detail! :)"thumbsup" Has the disassemble/rebuild begun yet? 8) I've seen the nice looking Vitavon CNC alum rear axle housings etcetera advertised but not seen how they actually perform. |

But i'd be all for it as it'd directly compete with the Losi Baja Rey. Seen a couple tracks run a race with them which is amazing (basically mini Super Stadium Truck races) I REALLY REALLY wanted one of these myself, but decided on spending less than half on a 1/10 scale Baja Rey. I'll live vicariously through you |

I bet you still have time to get one later! "thumbsup" https://oi1264.photobucket.com/album...5-IMG_1266.jpg The front diff from above, had to remove some of the front bulkhead screws to get it and the plastic middle slider drive shaft out. I replaced this shaft, as it is a weak spot in the drive system and isn't the easiest to get to. https://oi1264.photobucket.com/album...8-IMG_1272.jpg Next I removed the bottom access plate to get to the motor, center drive system, and servo. I wanted to go to a little taller gears so when I had the center Diff out I replaced the stock gearing with a 55t spur gear and 25t pinion. that took it from 1.95 to 2.05. Big speed and bashing isn't my thing and I'm thinking I may want to play on some rocks once in a while so trying to improve slow speed start up. (I hope) I may switch over to one of Holmes 1/8/ large scale motors, thinking this, 2200 smooth startup Puller. I also replaced the rear alum drive shaft with a hardened steel one. https://oi1264.photobucket.com/album...9-IMG_1273.jpg So I've been adding some of the other up grade parts and waiting on a few more to get this on to the dirt. I have said many times in some of my other builds that I enjoy the build more than the driving. Dumb I know, I guess it is the old man in me. |

Re: Codyboy's Unlimited Desert Racer WOW! this is very interesting to see what you will do with one of these... i'll be checking back for sure. Glad to see you staying busy young man! ;) *i would LOVE to see some CODYBOY red/white/blue livery in some sort of wrap on this. are clear bodies available? i would image so but admittedly i know nothing about this platform. VERY cool, though! |
Re: Codyboy's Unlimited Desert Racer Quote:
I have the clear body resting on my shelf as we speak, I want to do a modified off fender body for playing on the rocks.!!"thumbsup""thumbsup" Surly coming with me to Pro-line By the Fire! Ernie |
Re: Codyboy's Unlimited Desert Racer Can’t wait to see what you do with this. I have one on the way too. Never had a high speed rig but wanted something fun to play with right at the house on the dirt and grass. Hoping it holds up. Nice list of upgrades you’ve got there. I’m going to keep mine stock and hopefully just enjoy it for what it is. Ben |
Re: Codyboy's Unlimited Desert Racer Ernie, great that you have a clear body too! Ben, awesome you'll like it! Should be great fun jumping, sliding and blasting around the little quarry crawling area you have nearby too! Only few basic mods needed to keep them together, depending on how much you drive like Kevin. Metal front driveshaft, RPM trailing arms (or keep spare Traxxas arms), swap out Traxxas battery plugs for XT90 or XT150, E6000 to seal around rear axle where gear reduction unit/pinion attaches to housing and housing ends, and around transmission. I've been beating my X-Maxx and it's also doing great with few basic mods. :) |
Re: Codyboy's Unlimited Desert Racer Quote:
so... you're actually building a Traxxas ULTRA4 Desert Racer?!?!"thumbsup" i gotta see this thing how it handles some rocks... drag brake and maybe sludged up front diff?? all possible and my mind is racing how to make that work haha looking forward to seeing it at ASCENDER CAMP 2.0! 8) |
Re: Codyboy's Unlimited Desert Racer Quote:
I might just have to bring a basher too this year, I have an Arrma Senton 6S that might be able to keep up with the UDR. Cant wait for PLBTF! |
Re: Codyboy's Unlimited Desert Racer man you all are going to make my yeti feel slow haha well okay it actually kinda is... i hope i can finish the overhaul for a full reveal there. haven't had time but i like working under pressure. hope we can get the same spot as last year close to the huge ditch everyone was flying their slashes out of last year haha DESERT GO FASTS, ASSEMBLE!!!!! |
Re: Codyboy's Unlimited Desert Racer I just happened upon this thread, the bummer is I'm at work so I can 't view the awesome pictures until I get home. I want one of these to go with the X-maxx "thumbsup" |
Re: Codyboy's Unlimited Desert Racer Quote:
Unlike some of my build it won't be anything to crazy Ben."thumbsup" I know the stock setup isn't designed for rocks but I guess that's where the craziness comes into play! Quote:
Quote:
Nothing to crazy as far as changes Chris. Maybe tires, gearing, and ride height. I have the ESC changes covered with the Mamba Monster X, Casey covered that for me. Quote:
That would be cool Casey. Now we need to convince Nate to change his mind about not coming this year! Quote:
Hey Paul, getting ready to post up a few more. The 3.8 proline Badlands are right at 6" in dia, (stock tires are 5.25) and I don't thing they are going to play nice with the stock body. "thumbsup" https://oi1264.photobucket.com/album...1-IMG_1298.jpg Fully compress, I won't be able to turn. https://oi1264.photobucket.com/album...2-IMG_1299.jpg And I can't bring myself to cut up this pretty new body, so bought this one. https://oi1264.photobucket.com/album...3-IMG_1300.jpg https://oi1264.photobucket.com/album...4-IMG_1301.jpg Let the hacking begin! https://oi1264.photobucket.com/album...5-IMG_1302.jpg Front views. https://oi1264.photobucket.com/album...6-IMG_1303.jpg https://oi1264.photobucket.com/album...7-IMG_1304.jpg From the side. And a little shot of some of my burning projects. https://oi1264.photobucket.com/album...9-IMG_1306.jpg And a perspective view compared to another project I'm working on. ;-) https://oi1264.photobucket.com/album...0-IMG_1307.jpg https://oi1264.photobucket.com/album...1-IMG_1308.jpg Any suggestion on what I'm trying to do here? After I paint the body I'll reinforce it with sheetrock tape and E6000. "thumbsup" Later, Ernie |
Re: Codyboy's Unlimited Desert Racer Man Ernie! Your always building cool trucks! UDR rock crawling should be pretty interesting. Get one of these guys going to proline by the fire with you to shoot some video of that. Really digging that crawler you're building too! People get bored with your builds??? I can't get enough. If I could I would send you stuff to build just to see what you'd do to it:lmao: keep up the great work brother! "thumbsup" NATE!!!! Proline....by.....the fire.... With those guys ^.......GO!!!! :mrgreen: :lmao: |
Re: Codyboy's Unlimited Desert Racer The URD is looking mean all cut up, looks like plenty of room now. As for the other project, it looks like a lot of room for these tires too but I'm not quite sure what you're doing. Quote:
I will try to film this time, I planned to last year but it was hard with so much going on. Yes Nate reconsider! |
Re: Codyboy's Unlimited Desert Racer Yeah I will have a gopro with me this time, but like Casey says its hard to film with so much going on! Nate you gotta come down, what if I strip servo horns again?!?! Paul who will I complain about the raffle with!?!? lol But seriously... Last year was ridiculously fun! |
