I thought I start documenting progress with my Mojave 6S as I didn't for any other of my other Arrma trucks so here it goes:

1st time out of the box

Next to my Kraton 8S for size comparison (its the fast one as well ;) - green)

1582033163078.png


Width comparison significantly narrower than the Kraton 8S

1582033197859.png


Looking really good in the flesh

Step 1 - Precaution - stiffen up the body and add a bit of weight :ROFLMAO:
I have chosen to use Gorilla tape to strengthen the body a bit to hopefully preserve it longer

1582033411710.png


Step 2: Make it actually useable - adding a SR-215 (SMART upgrade applied via SPMA3065)

1582033495269.png


Threw out the SRX200 that came with it and installed the SR-215 using some servo double-sided tape

Step 3 - Order TBR Hop Ups for the Mojave

1x TBR Front Chassis Mud Guards - Arrma Mojave SKU: TBR-10132
1x TBR SC Basher Rear Bumper - Arrma Mojave SKU: TBR-10130
1x TBR XV4 Front Bumper - Arrma Mojave SKU: TBR-10129
1x TBR Rear Mud Guards - Arrma Mojave SKU: TBR-10131

waiting for delivery ....

I am thinking to try a few other things with this truck, I got some different tyres I may want to try out, also don't like the battery tray and will look for another solution to make this more comfortable, we will see where this platform goes, hence the build log.

Question
: Can you move the battery tray backwards on the Mojave 6S?

Response: Yes, you can and you get all the required mounting holes to line up as well.

1582069208068.png


As you can see below all 5 mounting holes will line up as well if you move the battery tray and receiver box backwards. So in case this was nose heavy at one point there is opportunity to counter it.

1582069235894.png


Still not the optimal solution for what I got in mind. I am thinking to keep the receiver box where it is and get a complete different battery tray to accommodate for my needs - further testing/exploration required.

Really sad day today: Expected TBR parts delivery did not turn up :banghead:

Well, expecting to do some lunch time wrenching I turned my thoughts to the below kindly supplied at a reasonable price by @arrmadave that I collected during my last USA visit. It was meant to go into a "future" truck, so the future is now and the truck is the Mojave 6S!

1582121347928.png


After taking off the servo horn I noticed some wiring going from the stock servo underneath the esc mounting plate. Had to inspect this before proceeding and I am not sure who came up with this idea but I don't like it. Four additional screws to remove when changing the servo, I get the idea get the wires out of the way and stop them dangling around but that is something a zip-tie could easily solve from my respective.

1582121256070.png


After removing the esc mounting plate and freeing the cable ...

1582121449520.png


... its time to remove the stock servo, mind the servo mounting spacers, I kept the stock servo mount for now which may introduce a little give when necessary

1582121497279.png


And here is the replacement which should help a little compared to the stock servo

Operating speed ( 5.0V ): 0.15 at 292oz or 21kg/cm
Operating speed ( 6.8V ): 0.13 at 349oz or 25kg/cm

1582121564919.png


And here it is installed and stupid me, did I say I didn't like the servo wire routing as this introduced four more screws in case this needs replacing? Well, uhm ... :banghead: :banghead: :banghead: :banghead: I kept it this way ... :ROFLMAO:
I have to say getting the receiver box gasket back in place is always the most painful exercise I don't know why ...

1582121989761.png


Resetting my transmitter so I can center and adjust the servo horn and throw accordingly but here is what I had previously as the servo horn always leaned slightly towards the esc (backwards) - tried jumping by 1 spline but that was too far off:

Previous Sub trim:

1582122176498.png


Previous Servo Travel:

1582122281590.png


Servo under power and servo horn looking pretty perpendicular to the servo:

1582122406579.png


New Servo Travel:

1582122486163.png


Sub Trim for now:

1582122438360.png


All thats left now is to confirm that is actually runs true and straight ... and wait for the TBR parts to continue outfitting the truck for off-road use.

Do you have part number for the servo?
I got mine from here

My Kraton 6s v4 is exactly the same.

Lovely!
 
Installing TBR Rear Mud Guards - Arrma Mojave

TBR supplies the 2 Rear Mud Guards and 4 screws. Not sure why but it seems my phone swallowed the pictures I have taken but here is the final result. They need to sit this way round I took pictures (that are lost) which showed that it binds the other way round.

Word of caution: I didn't like this install as the screws feel like they strip the Rear Lower Suspension Arms so it does not fully tighten by the feel of it.

1582215974696.png




Installing TBR Front Chassis Mud Guards - Arrma Mojave

TBR supplies 2 Chassis Mud Guards, a center/connector bracket, 2 inserts/washers and 2 long, 4 medium and 4 small screws as you can see below:

1582216222489.png


First remove the two screws from the Top Plate (as indicated) and then insert the inserts/washers into the openings

1582216505616.png


Looks as below

1582216583373.png


Next, move the center/connector bracket in place make sure the mounting connector for the chassis mud guards point upwards to not interfere with the moving servo arm and use the 2 long screws supplied in the package to secure it.

1582216689407.png


Now you need to remove the Side Impact Bumpers on both sides as this is where the actual Chassis Mud Guards mount to as well.

1582217187930.png


The large screws are obviously the stock side impact bumper screws and use 2 small screws supplied to lock the Chassis Mud Guard in place.

1582217276672.png


Screw the side impact bumpers back into place and then take 2 medium size screws supplied to mount the front of the mud guard to the center/connector bracket:

1582217408151.png


Make sure that the servo arm can freely move after the installation, there should be a gap between the servo arm and the center/connector bracket as well as it should not bind to the Chassis Mud Guard itself see below.

1582217518611.png


Proceed similar on the other side and the result will look like below

1582217563067.png


Here are a few shots to show how far up reaching the Chassis Mud Guards actually are

1582217612511.png

1582217633161.png


Looks pretty good to me so far but still need to confirm how much this will actually prevent once I run the Mojave off-road.
 
Decided to do a little after dinner wrenching and first had a look at installing the TBR SC Basher Rear Bumper - Arrma Mojave but decided against it as I prefer the stock one that comes on the truck - at least for the moment there will be no change, so resealed the bag in came in.

Installing TBR XV4 Front Bumper - Arrma Mojave

WTF, how those guys get away without supplying an instruction really makes me wonder!


Here are the contents that you get in the pack, 3 bumper pieces, 2 inserts, 2 washers, 3 nuts, 3 smaller flat head screws, 2 longer flat head screws, 2 longer round head screws and 4 thicker flat heads.

1582245249641.png


Obviously the stock bumper needs to come off so I started to take out these 2 screws that connect the Front Skid Plate Upper Brace to the front shock tower and hold the stock bumper in place.

1582245463416.png


Next turn the truck over and remove all 5 screws from the front skid plate. Thanks to different screw sizes you actually have to swap bits quite a few time ... frustration guaranteed on both sides Arrma and TBR :banghead:

1582245579003.png


Time to reverse engineer how these parts are supposed to fit together and you will figure out by using the skid plat part of the bumper that you will need to remove these 2 screws as well

1582247707047.png


Playing around with the inserts and washers if they may fit here results in the inserts may only fit on the top 2 screw locations and the washer needs to be used elsewhere.

Step 1
Take one of the smaller screws and a nut and connect the lower bumper part to the upper.

1582247775451.png


Step 2
Parts used

1582247811273.png


Now bring in the "middle" piece that will connect the bumper to the shock tower and use the other 2 small screws (that are slightly longer than the other one used previously) and 2 nuts.

1582247835470.png


Step 3
Figuring out how this will mount to the shock tower/front ... Remove the 2 screws to make space for the screws supplied in the kit.

1582247869851.png


Step 4
Take the longer round head screws and the 2 washers and feed them through the mounting plate

1582247889202.png


Step 5
Bring the bumper assembly into position and tighten it against the shock tower/front

1582247909750.png


This is whats left after Step 5 and you will need to figure out how to use it.

1582247944024.png

Step 6
The only logical and working option I found is below but place the spacer/insert into the top 2 mounting holes with the 2 thinner screws and use 2 of the ticker screws at the front 2 screw positions.

1582248141904.png


After everything is tightened up and in place for some reason you got 2 thicker screws left over, I reviewed the entire process and pictures I have taken and cannot find any possible scenario where those left over screws could go.

1582248160509.png


As I cant find where those 2 screws are supposed to go I assume that they may be spares or incorrectly supplied unfortunately they don't list what is actually being supplied so I can't check that either - instructions anyone??

Well here is how it all looks once its been installed:

1582248183636.png


Looks definitely like it may provide a bit more protection than the stuck assemble at least for the body but the body now rides directly on this lip here and I wonder if that may put additional stress to the body as the bumper flexes and causes damage to the body itself

1582248199740.png


Definitely a painful install with head scratching, trying to decipher the few pictures they have on their website to get an understanding how things may fit together and where to use which part.


As previously mentioned, I will keep the stock bumper assembly on the truck for now and if I see any signs of that being a bad idea I may look at replacing it with the TBR SC Rear Basher Bumper and if I see that the body suffers from this new front bumper assembler I will revert back to stock.

I really don't like TBR and this shows exactly why. No instructions and a half assed fit. I like the way the stock bumpers look. The TBR stuff is an eyesore. I'll do my best not to run headfirst into stuff ?

Great write up so people can see how to fit that monstrosity of a front bumper..???
The best thing is, I now know why the M2C hinge pin kit doesn't fit the Mojave..!! (picture 3,4 show the problem)

What he said...???
 
Thanks heaps r4nd0m , this write-up will help when my T-Bone guards arrive from the other side of the earth. Definitely saving yourself some hassle by installing this stuff before your first dirt or grass run.... believe me! I'm currently tearing mine down and rebuilding it with some minor upgrades to protect it from dirt, salty grass and rust.
