Looks like a really good find you got there! 

I really like these and a bit like you I keep thinking why haven't I had one yet - might have to start adding a couple to my watch list 

The handling “issues” and the fact youre told in the manual not to bash it put me off. Hopefully ill use it as in intended and drive it how its meant

True you need a different style of driving for the UDR.

Its a desert racer.

Don't do massive jumps, they are not designed for that. 

And cornering hard when on the power only results in a walk to go turn it over.

Treat it how its meant to be used and it will last and be loads of fun! 👍

Added an MIP driveshaft.  These are supposed to be the best option, but they look so damn boring:

 

This was the problem

The solution. Not that you can tell. I do like how MIP stuff still comes with spares/threadlock/grease

Is that grease on the CV joint? That's going to collect so much dirt.

these are so fun.

 

you can drive fast thru terrain over old roots and some stones ,

shocks are amazing in these ones, they swallow everything where other rigs starts bouncing and tumble womble,  these are stable and fun

you will love it, i know LOL

 

UDR is the best looking  1/7 shortcourse.   Scale looks is amazing in these.

 

FOX Body are the best looking body , i love the colors , absolute best livery.

 

Some cheap universal Led bars rear and front would be nice

So took this out again with the MIP rear driveshaft. First proper run. Some thoughts:

 

This is hard to drive, anything slightly erratic on grass and youre on the roof. 6S is too much IMO, its impossible to drive fast. This is a £900 truck, if this was my only RC, performance wise, Id be incredibly annoyed I spent that much on one for this performance. I think this vehicle is location specific. If you live in the Nevada Desert, this would be an incredible RC, everywhere else? im not so sure. Maybe 4S is better? Traxxas even say dont bash it so what do you do?
 

However, I didnt pay £900, and its not my only RC so lets give its a chance. It looks stunning and feels special. All of my RCs are on display on shelves. Every non RC person goes straight to this one and pushes the body down to see the realistic suspension flex. I decided to take it to somewhere smaller but more suitable terrain. Dust….

Its much more fun here. The steering is terrible at the moment (sloppy servo saver) so in a small area, took a few 20 point turns to get unstuck (although power drift works better). Sometimes youre better off steering by flooring it and spinning the rear. 
 

And Traxxas said no jumps but you know what….

As long as youre smooth (not like the above) she jumps very well. It looks so scale and cool in the air. Im starting to get this now, but you really do need this to be a luxury RC to compliment the rest of your RCs, combined with somewhere to run. 
 

Obviously I took it too far:

and broke an A arm

but that didnt stop me running, only noticed at the end

These are impossible drive at streets and hard-packed-terrain 🙂

You need loose surface

 

They are made to drive at loose sand 🙂

 

Sand beatches,  gravel pits , deserts . Autumn on leafes  WOW

and SNOW,    in snow  WOW these are awsome in snow i will tell

 

Great winter cars

frost or snow

 

Have you change the old oils in this rig ? 

Shocks and diffs,   important have fresh oils in shocks

 

Right after it has rain they are pretty fun at asphalt and in muddy conditions too

 

I have the Mojave EXB,  and i love it, its insane how Tough this is.

I have drive like insane with 8s and now 6s max6 combo full send.

Have not broke ANYTHING in it LOL.   it takes sick Mental Bashing like nothing

 

check this video please

 

You dont need those m2c nuts, all you need is 

new nuts with rough surface to the hard plastic wheels that Mojave got

The only downside with Mojave EXB is that it looks not near as good like the UDR.

Mojave have that TOY car looks sadly,   

 

The UDR is best real looking without Questions,  real Scale

 

Mojaves needs also extra grease in most bearings.

Atleast diff bearings,  wheelhub bearings, then they are fine

Hahaha.  yeah i did hate my too because Diff issues.

 

Now i have find way to have them last , it took alot time and many try´´s

I was very close give up.

 

Mojave EXB with smal wheels are great out of box,  never single Diff issue.

Same with the typhoons,  and 1/7 speedrunners.

 

I had many Traxxas cars that have totally fail.

Just because one or two fails totally, you cant get up the other ones that are great.

 

One thing is 100% sure.

Mojave EXB Is alot better car than UDR.  Alot more Durable and easy to fix with .

 

To be honest, Mojave EXB is in the top 3 list of worlds most durable cars .   If you can live with the TOY Car looks,  then this is one must have rig in the collection.

 

UDR is nice in right  surface conditions,  Scale looks are awsome too. Best looking 1/7 Short course.

Just Go 4s  and bigger pinion,  drive at loose sand surface and enjoy alot ,  i know you will

 

This is your best rig in snow high speed snow and ice/frost drifting 

, after rain,  muddy speeding,   sand beaches,  gravelpits ,  sand socker fields ,  autumn on fallen leafs,  🙂

So decided to have a look at the steering. This truck isnt fun to work on….. However.

Take lots of screws out:

Alot of those screws were rounded, so Ive ordered a screw set:

 

Stock plastic steering rods were bent somehow:

Which obviously hasnt helped handling. 
 

More wrenching:

 

I ended up using the stock servo saver bellcrank, with some washers on it. Seemed more heavy duty than the cheap one….. lesson learnt.

As you can see an arm is broken. After much back and forth (alot of people suggest going alloy on these) I just went with a stock one from Modelsport.

Next up is a shock rebuild I think…..

I needed to nick the Tx and Rx for another truck so decided to add this to my Noble NB4 and change the front arm whilst I was at it:

Theyre not even comparable models? The Mojave is a big short course, this is a live axle trophy truck?
