The Axial Racing Yeti™ SCORE® Trophy Truck® kit includes many of the necessary upgrades that will bulletproof your Yeti™ for the desert but, if you want a bomb proof Yeti™ that will survive almost anything, Axial has you covered!

When first receiving the Yeti SCORE Trophy Truck kit box, the artwork is second to none, even the inside will wow even the expert builder.

The instructions start out with the front differential. The instructions include suggestions for optional performance upgrades. Using these heavy duty over/ underdrive differential gears will yield different speeds and off road handling results. Overdriving the differential will increase higher speeds, but decrease low end torque while the underdrive set will do the opposite and can be used in conjunction with each other as well.  (AX30402, AX30401).

Next is the front suspension and body mount steps, the aluminum shock tower (AX31170) is an essential upgrade to improve shock performance over the plastic piece by minimizing any movement in the upper shock mounting area dramatically. Also an area that is often overlooked is the body mount (AX31169). By improving this area, it will help to decrease front body movement.

For the rear axle, the heavy duty over/underdrive differential gears are also available (AX30402, AX30401).

The AR60 axle includes a removable scale plastic differential cover in the kit, these are two of the optional aluminum covers (AX30829 & AX31429) which offer a better seal and protection.

There are also 2 different choices for aluminum link mounts, each ones have different performance advantages. The AX31433 gives you the option to mount the rear sway bar on top of the rear axle, while the AX30830 will allow you to dial in the rear link length and pinion angle.

When building the front independent suspension, using the aluminum front Toe block (AX30811) will keep the suspension arm hinge pin securely in place and also offers greater front end protection over the plastic part. Note that parts tree AX80100 is needed when ordering this piece.

Continuing on with the front suspension build is the front steering and camber links. The optional Yeti aluminum turnbuckle kit will decrease weight and increase front suspension strength.

The Yeti has a sealed gearbox and transfer case that includes metal gears that can handle the abuse of a brushless motor and ESC combo on 3S easily, one part in this area that can use improvement is the motor mount (AX31156), it allows the pinion and spur to spin freely and efficiently by keep the motor solidly in place.

25
26
27

After installing the motor mount you have several Axial spur gear options that allow you to dial in your Yeti’s speed and torque characteristics. Using the 64T spur will increase run times and torque while using the 56T spur will decrease run times but increase speed. Opting for the steel spur gear will minimize any broken teeth, just make sure proper gear mesh is achieved.

39

Also available are officially licensed Method 105 wheels in kit stock orange or optional green, white, and black to keep you visible and add some authentic racing flare.

42 43

With the shock build and installation, using the available hard anodized aluminum shock mounts (AX31166) will create a more sturdy mounting area as well as help with the suspension travel.

44
45

To increase the visual aspect and the durability of the shock, use the available licenced Aluminum King Racing Shock caps, collars, and spring retainer cups (AX31430 and AX31431).

46

The rear shock mounts and on the trailing arms allow for several different ways to tune your shocks, you can also mount a second set of shocks to help increase the dampening ability.

Axial Yeti SCORE Trophy Truck – Rivas Concepts Long Term Testing

tech_yetitest

20151024_184659

This is one of the first RTR version’s of Axial Yeti SCORE Trophy Trucks out to the public.   I have had this truck since October 24th 2015.

20151024_192511

The very first run Dominic Longoria and I took it to a local race track and did a short video.

20151123_144613

This truck has been run a lot, I stopped counting after 48 battery packs. It has been a blast.

20151123_144559 20160212_133754-01

Its been jumped, crashed, kind of abused. Hundreds of people have drove this very truck! It has been to a few events as a demo truck for people to drive, before it was released to market.

20160302_145157 20160310_120613 (2)

It was driven by some random people and a few 1:1 MINT400 drivers. So it has some miles on it for sure. I have had a servo horn screw back out and then in the month of May it took a 10-foot drop breaking the first part. So it has seen seven months of total abuse.  If you drive hard or abuse your trucks, parts will break and you may get away with it once or twice, but its flirting with the breaking point. I have heard people say these are designed to be abused so they shouldn’t break… Umm, I disagree and agree… While I do agree this rig is designed for abuse, I don’t agree that it shouldn’t break. That would mean that some parts are going to be way too soft. Breakage is something that is going to happen. It’s all a sliding scale as you don’t want it too hard or too soft. This truck has been driven pretty hard by lots of people and it stayed together beyond my initial expectation. Its taken a lot of abuse and It took a big drop to break it.

20160701_215349

20160701_212734

So here it sits at AXIALFEST 2016. This truck has never had any maintenance done. I do not recommend this at all, but I am going for a true longevity test. The wheels have never even been taken off. Zero upgrades and none of the parts have ever been changed out.

20160701_212721 20160701_213013

While at AXIALFEST2016 Johnathan Schultz said it was dirty, I said its never been worked on. He took it as a challenge and stripped this bad boy down.

20160701_221119 20160701_223131

Transmission dropped out along with a few debris and about to be opened for the very first time.

20160701_225906 20160701_233451

Everything still looks good! I was expecting a completely dry transmission and some metal shavings. 48+ battery packs and tons of desert dust berms, I’m impressed!

20160701_233135 20160701_222422

It did managed to get some dust in the receiver compartment, but Las Vegas has some seriously silty areas, so I expected this to be a lot dirtier.

20160701_220948

20160701_223505

I think you can tell how much run time and or abuse this truck has seen! The control arms and pan tell the stories of all the good times this rig has given.

20160701_223931

Again I am shocked, the front diff still has grease.

20160701_223925

There is no visible damage when the front end is opened.

20160701_225943 20160701_213752

The internals of the rear diff still look really good. If you only knew how many hours of drive time this drivetrain has seen.

20160701_224427

“It might be a racer thing,” Johnathan stated as he took apart every nut and bolt to clean it. But I was also reminded of a rumor I once heard about Johnathan’s father taking apart ScottG’s rig in the middle of a race to help him. Something about half in the garbage and the other half in a cardboard box and handed back to him and their heat was about to start… so I watched Johnathan like a hawk! I want this rig up and running to continue this long term test.

20160701_223343 20160701_223333

20160701_223858

It’s down to the floor pan. Now comes the cleaning.

20160701_224720

Some simple green, brush, and lots of elbow grease. This little venture has worked well into the night. Since we are at AXIALFEST2016 as part of the early crew setting up, we have a downtime in the evenings and we are just R/C 247′ing up!

20160701_225205 20160701_225652

Looks so much better than from when we started.

20160701_215913

The rear axle is cleaned and put back together.

20160701_234122

Transmission looks like knew, its hard to believe it looks this good after all its been through. It spins smooth, no squeaks, or noises.

20160701_234104

20160702_010425

Stock ESC, servo, and motor going back in.

20160702_010418 20160702_010428

If you scroll back to the top of the page you can see what a difference this is. One thing I will recommend if doing this, get new bearings before you do it. We replaced a few plastic ball ends, simply because they were worn and had some slop. Put shocks back in same position as stock, and I have added some 30 weight oil to the shocks, not full, just enough to lube them.

My thoughts on the Axial Yeti Trophy Truck.
I’ve really truly enjoyed driving this thing! It reacts and moves how I imagine a real SCORE Trophy Truck would. But hey, that’s the fun of R/C! The rear suspension drop is awesome to watch in action! It handles well out of the box, I couldn’t recommend this as a track truck, but I am not a track racer. The rear locker is fantastic off road, not sure if that’s beneficial on a track. I would recommend a higher pinion for a little more speed. If you purchase this for kids it’s plenty fast, 3S is the way to go. I have heard people are ripping the lexan bodies after a while, I had a wrap done on mine from SOR.Racing and you can see mine has not ripped or torn. Axial also has the Retro Bodies available. I have owned other trucks and you can only go fast so many times and jump so many things before you get bored. This is so scale I run it all over and don’t lose interest. It’s still fun because of how it runs and reacts as a whole.

It was definitely the “reset button” on 1/10 scale off road trucks in my opinion! When “short course” trucks came into the market there has been two groups of people who were attracted to the segment, but things change and transition as a natural progression. One group has almost transitioned back to what racing was prior to the short course trucks.

The other group are those who saw this as inspiration for the next step in scale progression with a live solid axle like the full size big desert racing machines called TROPHY TRUCKS! A Trophy Truck is NOT a short course truck! So thank you AXIAL for recognizing the difference and containing to appeal to the scale enthusiast!

While it took Axial a while to get here, it was a risky move as a business in the public face of R/C short course racing. It’s been funny to watch as most want to categorize the Yeti TT as a short course truck, that it is NOT! This rig offers everyone that same chance to hit the “RESTART BUTTON” on FUN! This is just like what short course trucks did when they came onto the market. For the scale community, this is our truck and the Yeti SCORE Trophy Truck is a MUST OWN truck!

In Axial we trust, scale we must!
Just my opinion,

Adding Lights to the Axial Yeti SCORE Trophy Truck

2016_blog_Adding Light_Yeti Score Trophy Truck_500px
Words and photos by Tony Phalen

A couple weeks ago I showed you how to install headlights, taillights and a roof mounted light bar on your Yeti SCORE Retro Trophy Truck body. It was a pretty simple process – but what if you have a standard Yeti SCORE Trophy Truck body? Well, thankfully the procedure is the same with just a few minor tweaks.

You’ll need a few tools to complete this job, listed here:

Tools
1. Body reamer or something similar to enlarge the holes in the plastic headlight/taillight parts.
2. Shoo Goo or something similar to secure the LEDs in place.
3. Hobby Knife.
4. Silver Sharpie. Optional, but great for that extra detail.
5. Tape. Black for securing wires to the cage, clear for securing wires to the inside of the body.
6. Y-connector for combining the front and rear light strings into one.
7. 6″ (or longer) servo lead extension.

I’ve also included all the Axial parts needed at the bottom of the article.

Let’s get started!

Step 1

Adding Lights to the Axial Yeti SCORE Trophy Truck
The first step will be to remove and modify the front and rear light buckets to accept a pair of LEDs a piece. The front bucket has only 1 hole – the left red arrow shows where you can ream out the hole to add a 2nd LED. Ream only a little at a time, test fitting the LED until it pushes in nice and snug. The rear bucket (on the right) has two holes, but you’ll need to make the lower one a little bigger to accept the larger LED. Again, open the hole a little at a time until the LED sits nice and snug.

I added a little detail to the front light buckets using a silver Sharpie. It’s not necessary by any means, but I do like the way it highlights the all-black buckets.

Step 2

Adding Lights to the Axial Yeti SCORE Trophy Truck  Re-install the front light buckets to the body and press the LEDs in place. Use a dab of Shoo Goo to hold the LEDs in place, letting it dry thoroughly. Route the wires as needed using clear tape to hold them down. Try to keep them in the raised sections of the body so the tires won’t hit them when traveling through rough, rocky terrain. I’ve also installed one of the 3-Port High-Output LED Controllers on the front hood. Route the left and right headlight strings over and plug them into the side-by-side plugs.

Step 3

Adding Lights to the Axial Yeti SCORE Trophy Truck
Using the same procedure as we used for the front, install the buckets and LEDs to the rear of the TT.

Step 4

Adding Lights to the Axial Yeti SCORE Trophy Truck
Run the LED power wires along the rear cage as shown, using the black tape to hold them in place. If you want to do a super trick, feed the wires through some black shrink tubing prior to attaching them.

Step 5

Adding Lights to the Axial Yeti SCORE Trophy Truck
The 2nd 3-Port High-Output LED Controller is mounted to the underside of the roof. Route the left and right taillight strings along the cage and plug them into the side-by-side plugs in the controller. I would suggest mounting the controller so that side-by-side plugs face the rear; if you decide to install a roof-mounted lightbar, it can plug into the single high-output plug facing the front.

Step 6

Adding Lights to the Axial Yeti SCORE Trophy Truck
Take both leads from the 3-Port High-Output Controllers and run them to either side of the TT body, using the clear tape to keep them in place. You may notice that the leads use 2 wires (and a mini-JST plug) while the Y-connector uses a 3-wire plug. That’s OK - just make sure that when you connect them, the black wire mates up to the black wire (or in this case, the brown wire).

Step 7

Adding Lights to the Axial Yeti SCORE Trophy Truck
Flip your TT over and remove the little hatch on the bottom of the chassis. This reveals the receiver we’ll need to plug the light string into. Pop the receiver off the tape and pull it out slightly, like the picture. You’ll also, at this time, want to remove the top black spacer in the clear silicone plug (the spacer is shown just to the left of the receiver box). Now, carefully feed your 6″ extension from the topside of the truck down to the receiver box. It’s a little tricky and you might have to push some other wires out of the way, but it is possible – and I suggest doing it from the top down.

Once you have it through, plug the 6″ extension into port #3, making sure the black wire (or brown wire) is facing the same way as the black wires already installed. Now, press the extension wire into the clear silicone plug, taking up the space of the black spacer you removed earlier.

Step 8

Adding Lights to the Axial Yeti SCORE Trophy Truck
Flip the truck over and you should have about this much of the 6″ extension left sticking out. Adjust how much of the extension is left (if necessary), flip the TT back over and press the receiver back into the box. Coil up any excess extension wire, push it into the receiver box and re-install the receiver box door.

Step 9

Adding Lights to the Axial Yeti SCORE Trophy Truck
Set the driver interior back into place, mate the Y-connector on the body to the 6″ extension and re-install the body.

Our SCORE Trophy Truck body is now ready for some night time driving. Plug the battery in, flip the switch on and check out your fantastic work! Here’s an example of how it should look when you’re finished:

Did you know that the Axial Yeti SCORE Trophy Truck comes pre-configured for LED lighting? Yup, that’s right, all you have to do is attain and install the LEDs, route the wiring to the receiver and enjoy some brightly lit evening drives.

In this article, I’ll take you through the step-by-step process of installing a full set of LEDs in the front and rear buckets as well as adding an Axial Universal Rigid Light Bar Set. In addition to all the lighting components (listed at the end of the article), you’ll also need a few other tools to make the installation easy.

Tools
1. Body reamer or something similar to enlarge the holes in the plastic headlight/taillight parts and for making holes in the body.
2. Shoo Goo or something similar to secure the LEDs in place.
3. Hobby Knife.
4. Silver Sharpie. Optional, but great for that extra detail.
5. Tape. Black for securing wires to the cage, clear for securing wires to the inside of the body.
6. Y-connector for combining the front and rear light strings into one.
7. 6″ (or longer) servo lead extension.

Step 1

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Before installing the LEDs in the light buckets, there is a little bit of prep work that needs to be done first. The buckets have provisions for 2 LEDs; 1 standard headlight and one smaller turn signal. Since I wanted to have both sockets use the super bright LEDs (for a headlight and driving/fog light), I had to use the reamer to open the hole up in the smaller socket to fit the larger LED. Widen the hole in small increments, test fitting the LED a couple times until the fit is nice and snug.

For some added detail, I highlighted the area with a silver Sharpie. I think it turned out pretty cool looking and having it mounted behind the Lexan body helps protect it.

Step 2

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Once you have the front buckets mounted, press fit the LEDs into the them. We have two solutions to securing the LEDs; you can use the supplied cap and screw (left LED) or Shoo Goo (right LED). Either method works great but since I didn’t have enough of the small 2-56 screws to complete the project, I opted for Shoo Goo.

Step 3

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Using the same procedure, install the buckets and LEDs on the rear of the Retro TT body. You’ll need to ream out the smaller hole in this bucket as well. Since I was using the red tail light stickers on the rear of the Retro body, I opted to use white LEDs. You could also use red ones here instead for more red lighting – I listed the red LED part numbers at the end as well.

Step 4

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Route the rear LED power leads along the rear cage and secure with the black tape. This helps keep the wires away from the spinning tires. If you have some available, you can feed the wires through some shrink tubing for added protection.

Step 5

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Build and mount Axial’s roof-mounted LED bar. A slit can be cut into the roof to pass the wires through. We won’t get into detail about building it – it’s pretty simple. Just take a little extra care to make sure it’s mounted square on the roof.

Step 6

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Flip the Retro TT body over and feed both the front and rear LED power leads into an AX31097 3-Port High Output LED Controller (use double-sided tape to secure the controllers on the body). The roof mounted LED light bar will connect to the high-output port on the rear 3-Port High Output LED Controller. Masterfully tape all the wires down using the clear tape.

Step 7

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Feed the 3-Port High Output LED Controller leads to the side of the body and tape them down using the clear tape. Take your Y-connector and connect them as shown. The LED controller wires use a 2-wire, mini JST plug – our Y-connector has standard 3-wire plug. Just make sure the black wires match up and you’ll be good to go. You can add a little extra tape here to secure any additional wires.

Step 8

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Next, we’ll be installing the 6″ extension, so start by removing the little door on the bottom of your TT to expose the receiver compartment. You may need to ‘pop’ the receiver off of the tape used to secure it to make this a little easier. You’ll also need to remove the little black spacer used in the clear silicone grommet. We’ll be filling that space with the new 6″ wire.

I found it way easier to feed the 6″ extension down to the box from the top of the truck and into the box. Insert the 6″ extension plug into your receiver with the negative wire (black or brown) towards the outside of the receiver. Press the wire into the clear silicone grommet, making sure it’s down below the top of the grommet.

Step 9

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Turn the truck over and inspect how much of the 6″ extension you have available. This picture shows an adequate amount you’ll need. Flip the TT back over, press the receiver back into place and coil up any additional wire into the receiver box. Replace the receiver box cover.

Step 10

Adding Lights to the Axial Yeti SCORE Retro Trophy Truck
Install the plastic interior in place, connect the lighting power wires (black to brown in this case) and fit the Retro body to your TT. We’ve left enough slack in the wire to remove the body without having to unplug the wires each time, but if you feel it’s too long you can always shorten the lead by pulling a little more into the receiver box.

And just like that, we’ve got some very bright lights on our Retro bodied TT! Here’s an example of how it should look when you’re finished:

How To Convert SCORE Trophy Truck Wheels to Hex Style Short Course Wheels

convert_tt01_500px

How to convert your Score Trophy Truck wheels to Hex style Short Course wheels to open up more wheel options for your truck.

Words and Photos by John Schultz

You will need the following tools and parts:

- 1.5mm Allen for Wheel Hexs

- 2 mm Allen for rear straight Axle

- 2.5 mm Allen for trailing arm Mounts bolts

- 7 mm Hex driver for the Wheels

AX31290 AR60 Full width Axle Adapter set

AX30427 Axial Narrow Hubs

You will need 2.2/3.0 Wheels of your choice. I used Renegades Beadlocks from Proline #2731-01.

Then, choose the tires of your choice. I used the Axial AX31294 BF Goodrich KR2 R35 compound for better performance and scale looks.

The only thing you need to change on the front are the front AX30427 Axial Narrow Hubs. Mount the wheels and tires and bolt them on. Now the front end is complete.

convert_tt02_500px

convert_tt03_500px

The rear takes a little more work, but is still very easy to do!  Follow the instructions in the AX31290 AR60 Axle Adapter kit. It should take about 15 minutes to install. Also make sure you install the AX30427 Axial Narrow Hubs and bolt on your new wheels and tires.

Here’s a little short cut –  if you take out one of the bolts that goes into the trailing arm mount, the axle will slide out easier.

Even with my beat up body it still looks good!!

JPRC Yeti Trophy Truck Epic Trail Run – VIDEO

JPRC_Yeti_RedBull_TT_500px

Slow motion video, long wheel travel, wheels tucking up into a Trophy Truck body mixed in with off road bashing is a lot like attempting to say “NO” to that last cookie in the cookie jar. It’s fair to assume that cookie didn’t stand a chance, just like this video had to be watched. If you’ve been following JPRC’s YouTube page you’ll notice he’s a fan of Trophy Trucks, if not, make sure to take a few moments and check out his page.

AXIAL STAFF: RETRO TT BUILDS

2016_blog_EPTTBUILD_500px

Given the opportunity to paint up a few SCORE® Retro Trophy Truck® bodies for the up coming body release, Axial staff nabbed a few bodies and took some creative liberty and ran with it. Lets be honest, wouldn’t have you? And from the looks of it each body has its own unique flare ranging from an old school Las Vegas race truck flare to budget Trophy Truck® with multi colored fender panels. Despite all the differences, all chose to use the full roll cage assembly for full effect. Here is a closer look into each vehicle.

Yeti SCORE Trophy Truck Full Option Build

Words and photos by Tony Phalen

Whenever I get a new vehicle, I like to take the first couple weeks to just drive it in box-stock form to learn about its traits; how it handles, any quirky nuances, etc. During this time I also take some time to review any hop ups that might become available, giving me an idea on how my long-term upgrade process is going to play out. Thankfully, the SCORE Trophy Truck shares the same platform as the Yeti Rock Racer, which means that there are a slew of performance goodies already available. Armed with a bag of aluminum bits, I decided it was time to install them prior to getting this rig all dirty. Not only did that make it a lot easier to deal with (read: no dirt!), it also looks much prettier in pictures. Time for an Axial Yeti SCORE Trophy Truck Full Option Build!

Step 1

Axial Yeti SCORE Trophy Truck Full Option Build Here are the parts I’ll be installing in this article. I’ve got quite a bit of work ahead; shocks, gears, machined parts and turnbuckles. A full list of the parts I installed is included at the bottom of this article.

Step 2

Axial Yeti SCORE Trophy Truck Full Option Build Since I’m going to need to remove the center transmission for upgrades, I disconnected the motor wires from the ESC. Pay attention to how the wires connect; if you have a photographic memory, you’re good to go. If not (like me), you can mark them to keep things straight. I put one silver mark for the A wire, 2 for the B and 3 for the C.

Step 3

Axial Yeti SCORE Trophy Truck Full Option Build I’m going to be working on the front end of the SCORE TT first. I started by removing the top deck support brace. It requires the removal of 10 screws in two different lengths so, to keep things organized, I put them back in the holes after removal.

Step 4

Axial Yeti SCORE Trophy Truck Full Option Build Once the top deck support brace has been lifted off, removal of the front clip is easy. There are 4 screws underneath the chassis and the two hinge pin screws. I also disconnected the fixed-length steering turnbuckles as well – I’m replacing them with adjustable ones.

Step 5

Axial Yeti SCORE Trophy Truck Full Option Build Separate the gearbox from the shock tower by removing the 4 screws holding them together. I’m only working with the differential at this time so I set the rest of the front clip assembly aside. Note the orientation of the diff in the gearbox. You’ll want to make sure you re-install it the same way.

Step 6

Axial Yeti SCORE Trophy Truck Full Option Build Next, I removed the differential and bevel gear assemblies from the gearbox. I’m replacing them with the AX30395 Heavy Duty Bevel Gear Set shown in the picture. One thing to notice is that the assemblies have straight cut gears; this design is pretty strong and easy to machine. The new HD versions are helical cut, or machined with a slight angle in them. These are great for high-torque applications like crawlers or, in this case, hardcore trophy trucks! To replace, remove the 4 screws on the diff to release the gear, set the new gear in place and re-install the 4 screws. If you’re the tinkering type, you might think about adding some optional fluid to the diff prior to putting it back together (I did, 1000wt). The HD bevel gear is a one-piece unit so replacing the stock part is a simple pull-and-replace operation. One final step I performed was to remove the rubber stops that are installed in each diff outdrive. If you hold the diff on its side, you’ll see them down inside there. These are used to keep the dogbones tight and prevent them from ejecting during a hard crash, however they hinder the up and down suspension movement slightly. Since I’ll be replacing the dogbones with universals, they’re not needed anymore.

Step 7

Axial Yeti SCORE Trophy Truck Full Option Build Next up was the AX31170 Machined Front Shock Tower and AX31169 Machined Body Post Mount. These parts are a direct bolt on and work the same as the stock parts, however as you can see there are a few extra pieces. I’ll get to those in a bit.

Step 8

Axial Yeti SCORE Trophy Truck Full Option Build I disassembled the front clip down to the front shock tower assembly. The only part I’ll be reusing from this is the plastic body post.

Step 9

Axial Yeti SCORE Trophy Truck Full Option Build I attached the AX31169 Machined Body Post Mount to the AX31170 Machined Front Shock Tower. Since this is an aluminum-to-aluminum connection, I used a dab of threadlocker on the screws to make sure they don’t loosen up. I slid the plastic body post into the mount and used the screws provided to secure.

Step 10

Axial Yeti SCORE Trophy Truck Full Option Build I’m ditching the stock dogbone setup for a set of Axial’s AX31135 94mm Universal Axle Set. These come as a pair, are pre-assembled and slide right into place.

Step 11

Axial Yeti SCORE Trophy Truck Full Option Build I re-assembled the front clip – the new shock tower to the gearbox and the front bumper to the tower. I left the shocks off for now since I was replacing them with a full set of Axial’s Icons. You can also see the aluminum upper shock mounts that are included with the aluminum shock tower.

Step 12

Axial Yeti SCORE Trophy Truck Full Option Build For strength and additional tuning, I’m adding a full set of front adjustable turnbuckles (AX31249 Yeti Turnbuckle Set). This kit includes an excellent build sheet, so assembly is very easy. Just build the turnbuckles to the appropriate lengths and you’re good to go. I would suggest keeping them separate during the build so you don’t mix up the steering links with the camber links; the two are different.

Step 13

Axial Yeti SCORE Trophy Truck Full Option Build Before attaching the front clip back on the TT, I need to do a little work on the transmission. I pulled it from the TT and removed the gear cover, motor, plastic backing plate and plastic motor mount.

Step 14

Axial Yeti SCORE Trophy Truck Full Option Build I installed Axial’s AX31156 Machined Adjustable Motor Mount, a 2-piece unit that includes the main mount that attaches to the gearbox and a mount that attaches to the motor. The motor mount part swivels to adjust the gear mesh and uses an upper clamp to keep it securely in place. Because it’s aluminum, this system is SUPER strong and helps pull unwanted heat away from the motor. I re-attached the plastic backing plate followed by the spur gear assembly (I used Axial’s AX31161 32P 64T Steel Spur Gear and AX31164 Machined Slipper Plates in place of the stock parts). These upgrades look awesome and should make the gearbox virtually bulletproof. After I tightened everything up, I went ahead and re-installed the gearbox into the TT.

Step 15

Axial Yeti SCORE Trophy Truck Full Option Build Time to get the front back together, so I started by sliding the front clip onto the chassis and securing with the 4 screws from underneath as well as the two hinge pins. I made sure to key the center universal into the outdrive located under the transmission. It’s a little tricky, so I would suggest rotating the transmission gears (using the back tires) until you see the slots in the outdrive; this will make it easier to key the universal. Next, I slid the front axles through the steering blocks, attaching the wheel hexes to keep them in place. I installed the steering and camber links, making sure to key the axle bones into the outdrives. A little care has to be taken here to make sure the axle bones stay inside the outdrive.

Step 16

Axial Yeti SCORE Trophy Truck Full Option Build Now that the front is back on and looking good, it was time to move on to the rear clip and the installation of a lot of performance parts. The first thing I needed to do is separate the rear clip from the rest of the chassis; front cage screws, rear cage screws and the 4-link mounts. If you did it right, this is what you should be left with.

Step 17

Axial Yeti SCORE Trophy Truck Full Option Build My first plan of attack is the rear differential. To extract it, I needed to remove the diff cover, the straight axle hub carriers and the axles (just pull them out slightly). I also removed the two plastic diff-capture plates that hold the diff in place. Note the orientation of the diff gear inside the housing.

Step 18

Axial Yeti SCORE Trophy Truck Full Option Build Replacement of the diff gear and bevel gear is the same as the front. Once completed, re-assemble by inserting the diff gear, diff-capture plates and axles (key and slide back into place). I installed the optional AX30789 AR60 OCP Aluminum Straight Axle Hub Carrier.

Step 19

Axial Yeti SCORE Trophy Truck Full Option Build To strengthen the rear end, I replaced the stock plastic 4-link mount with the AX31165 Machined 4-Link Mounts as well as added Axial’s AX31244 Upper Link Plate Set. Both are direct bolt ons; the Upper Link Plate Set uses existing holes in the plastic links.

Step 20

Axial Yeti SCORE Trophy Truck Full Option Build I also installed Axial’s AX31245 Lower Link Plate Set. These also bolt right on using existing holes in the plastic links. I would suggest installing and tightening the two end screws while leaving the centermost pair loose. They can be tightened up when you re-install the shocks and anti-roll bar.

Step 21

Axial Yeti SCORE Trophy Truck Full Option Build Here is the rear clip assembled with all of the aluminum parts installed. You can see I’ve also added the AX31166 Machined Shock Mount Plates, AX30830 AR60 OCP Machined Link Mounts and AX31167 Machined Sway Bar Clamps. The Machined Sway Bar Clamps are a little hard to see, but I’ve added some additional pictures at the end that help show their install. When re-attaching the rear clip back to the chassis, add some threadlocker to the screws that secure the aluminum 4-link mounts. This will help prevent the screws from backing out when you’re out having a good time.

Step 22

Axial Yeti SCORE Trophy Truck Full Option Build While I loved the look of the King shocks, I couldn’t pass up installing a full set of Axial’s Icons. Per the included instructions, I built a set of front and rears and installed them in place of the Kings. I have an additional set of shocks to create a dual-shock setup, but I’m going to give it a whirl with the single shocks first. The dual-shock install (and tuning) will be for a later article. As you can see from the pictures, the aluminum parts look awesome and will provide additional strength as well as give the truck a bit more of a ‘factory’ look. Time for me to get outside and get this thing dirty!

Yeti™ Trophy Truck® – Geared for Speed

tech_yetittgeared

Straight out of the box, the Yeti Trophy Truck features gearing (16T pinion / 64T spur gear) best suited for extended run time on a 3S LiPo 5000 mAh battery. While this gearing yields a healthy amount of run time on both 2S and 3S (perfect for extended outdoor adventures), as customers, we are always looking for MORE SPEED. This is likely due to the fact that once people experience just how capable a Yeti Trophy Truck is in the wild, the tendency to want more speed becomes an overwhelming thought. Truth is… it can handle more, although more than what Axial offers with regard to available pinion gears.

After extensive testing with a variety of battery / pinion / spur gear combinations, we came to the following conclusion for best run time and speed on 2S and 3S:

2S 5000 mAh – 21T pinion / 64T spur gear • top speed 20mph • 15 minutes of run time 3S 5000 mAh - 21T pinion / 64T spur gear • top speed 32mph • 20 minutes of run time

The largest pinion we currently offer is 17T (AX30843 Pinion Gear 32P 17T – Steel (5mm Motor Shaft)), which will give you more speed than the stock 16T pinion gear, but not much. Please keep in mind that going with pinion gears higher than 21T will put more strain on your motor, resulting in potentially dangerous higher temperatures. For our test, we used a Robinson Racing 21T pinion gear (http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXDZFG&P=7).
