Soze rejoices the Traxxas TRX4 Sport Kit
 

Traxxas.... Kit.... Two things that I never thought would go together again since the 80's. Yes, they did come out with that chassis kit with all the electronic doo-dads that I didn't want... so I passed on it. They came out with a TRX4 Sport which is exactly what I wanted from the platform, but no kit was in sight, so I bought the RTR. Lo and behold... The day finally came where Traxxas released what I think a lot of others besides myself were clamoring for. Insta-buy.

My build is going to start out pretty much stock at first, and maybe deviate a little once I tie-up my multi-other projects that I'm working on. I think I bit off more than I could chew grabbing most of the other base platforms out there from other manufacturers at the same time.

Let's begin...

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Good to see you finally building the Sport, Sport! :mrgreen:

Is that blue grease on the gears the Versachem Brake Caliper Grease? If so how does it compare to Axial's grease, Vanquish's grease, marine grease or something else you have experience with?

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

NICE! you are killing it with these builds man. your part 3 came out on my feed right next to those other youtube guys... KILLING IT! also tell Mrs. Soze we said THANK YOU for letting you play so much!
hopefully i can convince my father in law he needs one of these in time for proline by the fire...

keep up the incredible work sir!

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

I actually started using Versachem from seeing Jeepiac talk about it. It's tacky so it stays on pretty well. I could probably go lighter on the grease, but once you give it a good run it seems to thin out, or at least get moved to the side of the teeth so that there is a thinner coating left on the gear teeth.

If I used nitrile gloves I'd probably do a better job spreading it using less because I hate the way it feels on my hands... but since I don't I usually just put more and then rotate the gears to make sure it spreads evenly while trying to avoid getting the grease all over the place.

I can't remember what Axial's grease is like, but I probably have a tube of it somewhere. I haven't used the other two.

I've also started trying Permatex anti-seize on the universals/cvds. It goes on really light and spreads really easily and evenly. It doesn't seem like dirt/grit will be sticking to those joints with it which is the reason I switched to it. I'm still testing it out though, and I'll try it out at CDM rocks (sand) when I get the chance.

LOL thanks. Man it's actually hard to get time. I get 1 hour in the evenings and maybe 2 hours in the morning on weekends.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Section B: Rear Axle Assembly

Yay, we move on to the axles!


You need this rear axle parts bag.

https://farm8.staticflickr.com/7888/...b238ca64_b.jpg


You also need the spool bag.

https://farm8.staticflickr.com/7874/...71c5db50_b.jpg


Step B1 Parts

https://farm8.staticflickr.com/7811/...5f88c919_b.jpg


Step B1 Complete

https://farm8.staticflickr.com/7892/...a4b2455b_b.jpg


Step B2 parts

https://farm8.staticflickr.com/7910/...173bc157_b.jpg


I think some have had issues with getting the diff plugs go though easily, but it didn't seem to be an issue on my build at all.

The e-clips on the other hand.... yeah we all know by now that I hate e-clips.


Step B2 complete

https://farm8.staticflickr.com/7923/...33994dd1_b.jpg


Parts for Step B3

https://farm8.staticflickr.com/7870/...933b5861_b.jpg


You need to be very careful with the ball bearing sizes used in this step. The 5x11x4mm bearing is shown with blue shield in the instructions, but in reality it's black. So carefully measure the bearing sizes, or just match it up with the instructions since it's 1:1 scale.

Step B3 complete

https://farm8.staticflickr.com/7892/...1035a913_b.jpg


Parts for Step B4

https://farm8.staticflickr.com/7829/...2761b029_b.jpg


Step B4 complete. Make sure to not overtighten the diff cover.

https://farm8.staticflickr.com/7839/...f26e6561_b.jpg


Parts for Step B5

https://farm8.staticflickr.com/7829/...c5dc36ef_b.jpg


What I liked about the parts for this step is that the parts clearly had identifying markers for which part goes on the left and right. Nothing left up to vagueness.


Step B5 complete.

https://farm8.staticflickr.com/7809/...6411ef58_b.jpg


Parts for Step B6

https://farm8.staticflickr.com/7917/...1161c819_b.jpg


Again, with this step, you need to carefully match up the ball bearing sizes. The 6x12x4mm is shown with blue shield in the instruction manual, but they are all black shielded. Measure carefully, or match up carefully with 1:1 illustration in the instruction manual.


Step B6 complete

https://farm8.staticflickr.com/7890/...3fbdf398_b.jpg


Parts for Step B7

https://farm8.staticflickr.com/7829/...b7719f04_b.jpg


Step B7 complete. In the picture it looks like I used too much grease, but that's not the amount that it actually ended up with. What I usually do is pack the grease on thick, close up the assembly and give it a good few rotations to spread the grease out, then remove the excess. Didn't bother to or rather forgot to another picture post excess removal though.

https://farm8.staticflickr.com/7855/...9d2a994f_b.jpg


Parts for Step B8

https://farm8.staticflickr.com/7855/...eb5e49f5_b.jpg


Step B8 complete. Be sure not to over-tighten the screws in this step.

https://farm8.staticflickr.com/7900/...cc746901_b.jpg


Step B9 parts

https://farm8.staticflickr.com/7816/...a086a76b_b.jpg

https://farm8.staticflickr.com/7864/...0ce3a5c3_b.jpg


Parts for Step B10

https://farm8.staticflickr.com/7890/...967da809_b.jpg


No need for fiddly pins that fall out of the hexes! Thank you Traxxas! Was nice that this kit comes with metal wheel hexes and locking screw pins.


Step B10 complete

https://farm8.staticflickr.com/7819/...42b562b4_b.jpg

https://farm8.staticflickr.com/7923/...fbf4b85c_b.jpg


And... we're done with Section B - Rear Axle Assembly.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Great thread Soze! Happy to see another sport build

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

That grease sounds like the stuff I've used. It does seem like you know when you put too much on because it always gets pushed to the outside.

Good start to a thread!

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Section C: Front Axle Assembly


You'll need the front axle parts bag.

https://farm8.staticflickr.com/7803/...9967bf59_b.jpg



Steps C1- C4 are pretty much the same as the rear axle assembly steps B1-B4, so I'll skip over those.


Parts for Step C5

https://farm8.staticflickr.com/7869/...21254c4c_b.jpg


Step C5 complete

https://farm8.staticflickr.com/7857/...242e5e4a_b.jpg


Step C6 is the same as rear axle Step B6

https://farm8.staticflickr.com/7855/...482f23dd_b.jpg


Parts for Step C7

https://farm8.staticflickr.com/7887/...91e2650c_b.jpg

https://farm8.staticflickr.com/7875/...5e07db7b_b.jpg


Also trying out/starting to use Permatex anti-seize on my CVD/Universal joints.

https://farm8.staticflickr.com/7877/...62b6c4c1_b.jpg


You can put on a little of it, and it spreads really easily and evenly with a few rotations.

https://farm8.staticflickr.com/7882/...6fd49679_b.jpg


Versachem grease on the gears

Step C8 complete

https://farm8.staticflickr.com/7808/...8155182b_b.jpg


Step C9 is basically the same as rear axle Step B10 except one of the link mounts is now a link mount + panhard mount.

https://farm8.staticflickr.com/7871/...a0e5b2d2_b.jpg


And now we're done with Section C - Front Axle Assembly.


We now have a set of TRX4 Sport axles!

https://farm8.staticflickr.com/7829/...cecc52ca_b.jpg

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

I use the same thing on my universals for the same reason. Have been using it for a couple of years and have had 0 issues. I also use it on the pivot balls for link ends...

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Yeah, I go through this kind of tedious process with the grease of packing it on thick first, then removing excess later. Sometimes I don't even remove the excess right away. I'll finish the build, put in a few packs... then go back and clean out any excess. I figure putting it under light power a few times helps the grease spread out evenly, plus I get to check if I actually missed anything when I open it back up.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

I may have even picked up the suggestion from you. One of the many reasons why forums are better than social media for documenting builds. Anyway, I did go back to my older builds and cleaned off all the grease I was using on those CVDs and replaced with this Permatex stuff.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Section D: Chassis Assembly

Can start to see the build coming together now.


Here is the parts bag that you'll need.

https://farm8.staticflickr.com/7867/...6b7ffc3d_b.jpg

https://farm8.staticflickr.com/7822/...ba6fa1c2_b.jpg


You'll need these for Step D1

https://farm8.staticflickr.com/7851/...7fa74932_b.jpg


Parts for Step D2

https://farm8.staticflickr.com/7912/...18d11f87_b.jpg


Once again, it's nice that Traxxas clearly marked pieces with FR, FL, RR, RL so that there is no confusion which brackets go where.

https://farm8.staticflickr.com/7897/...93872033_b.jpg


Parts for Step D7 - you'll notice one 3x10mm is missing. It was missing from my parts bag, but I had a spare one from my parts bins.

https://farm8.staticflickr.com/7802/...5acf0b3a_b.jpg


Step D7 complete

https://farm8.staticflickr.com/7851/...a17a715b_b.jpg


That's all for Section D: Chassis Assembly

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

I was missing the 3x10mm as well. My kit also missing a servo screw and one for the front light socket. It must just be the batch.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

I wasn't missing any screws, but I was astounded that there were very few leftovers and absolutely no c-clips.

Did your chassis rails come pre-scratched like mine?

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

I had scratches, but I'm not sure if it was pre-scratched or self scratched! :lmao:

I could see it getting scratched in the bag though... the frame rails are rubbing up on each other as packaged.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

That anti seize you used on the CVD's reminds me of some stuff I used at work a few years ago. It actually contained silver! So wasn't cheap, but I wasn't paying for it :twisted:

Nice to see another sport build. The quality of kits recently is getting much better that just a short time ago. i was very impressed with my Venture SBK. Seems like companies are realising people won't buy crap any more. Can only be a good thing.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Section E: Electronics Installation

So as far as electronics go, I'll be using the following:

Turnigy MG959 V2 Servo (eBay)
Holmes Hobbies Trailmaster Sport 550 21T Brushed motor (eBay)
FlySky GR3E 2.4GHz 3-Channel Receiver (eBay)
FlySky GT-3C 2.4 GHz Radio (eBay)
HobbyWing Quicrun WP-1080 Esc (ebay)


You'll need the electronics parts bag for this section

https://farm8.staticflickr.com/7891/...21a08bdb_b.jpg


Step E1 Parts

https://farm8.staticflickr.com/7836/...e2d9e308_b.jpg


Step E1 complete. Fits like a glove.

https://farm8.staticflickr.com/7822/...c6e4ba70_b.jpg


Step E2 parts

https://farm8.staticflickr.com/7915/...936515cd_b.jpg


You'll notice that I'm using the stock 17T pinion, and the stock 39T spur from the earlier transmission step. I'm building it as is initially as I'm using the Holmes Hobbies 21T 550 motor instead of the Traxxas 21T Titan Reverse 550. I've already purchased the 45T spur + pads and 12T/13T pinions to be used later.


Using a Holmes Hobbies 550 21T Trailmaster Sport. I really should swap to using bullet plugs, but I've got a bunch of Tamiya style connectors in my parts... and it just makes sense to use them.

https://farm8.staticflickr.com/7833/...e755b300_b.jpg


So the Holmes Hobbies motor shaft is shorter than a Traxxas Titan motor shaft, so I had to mount the pinion the opposite way from what the instructions wanted.

https://farm8.staticflickr.com/7927/...c43e446f_b.jpg


With the stock 17T pinion + 39T spur, we'll be using the "C" mounting hole on the motor mount. I might look into updating this part later on.

https://farm8.staticflickr.com/7914/...37f9eb01_b.jpg


Step E2 complete

https://farm8.staticflickr.com/7875/...e1fb70e2_b.jpg


Parts for Step E3

https://farm8.staticflickr.com/7863/...7901cc8d_b.jpg


Step E3 complete. Using a FlySky GR3E receiver so there were a few challenges in regards to the length of antenna, receiver wire lengths, etc.

https://farm8.staticflickr.com/7883/...643f8c9c_b.jpg


Step E4 parts

https://farm8.staticflickr.com/7832/...4d881f72_b.jpg


Using a Turnigy MG959v2 servo that I had on hand for now.

https://farm8.staticflickr.com/7851/...9c263a01_b.jpg


Step E4 complete

https://farm8.staticflickr.com/7915/...52b39e26_b.jpg


Step E5 had two 3x12mm screws used for mounting the Traxxas esc. I'm using a Hobbywing Quicrun WP1080, so those weren't needed.

https://farm8.staticflickr.com/7909/...8d842caf_b.jpg

https://farm8.staticflickr.com/7892/...c865551c_b.jpg


Step E6 parts

https://farm8.staticflickr.com/7836/...c3a7d115_b.jpg


Step E6 complete. You can see I rotated my receiver around. I did it to accomodate wire lengths. I'm still playing around with it to see if I can get the receiver light to line up with the receiver light window on the case.

https://farm8.staticflickr.com/7810/...ba2c507d_b.jpg


Step E7 Parts

https://farm8.staticflickr.com/7806/...193faed2_b.jpg


Step E8 is basically routing the wires to the receiver and securing them with the included zip ties. I had to create 2 wire extensions as neither the servo nor the esc wire was long enough to reach the inside of the box comfortably. It looks like I'll have to create 2 more longer ones so that I can turn the receiver around to the other orientation and hopefully line up the light to the light case light window.

https://farm8.staticflickr.com/7868/...31d191ef_b.jpg

https://farm8.staticflickr.com/7873/...5a41ac7d_b.jpg


Parts for Step E9

https://farm8.staticflickr.com/7834/...9a046742_b.jpg


You need to grease the foam seal on the receiver box outlet

https://farm8.staticflickr.com/7897/...86cbd2c8_b.jpg


Receiver box o-ring in place

https://farm8.staticflickr.com/7885/...b371f2d1_b.jpg


Step E10 completed. I have a feeling this is going to be coming off eventually for a 3D printed low center of gravity tray in the future.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Yours were probably pre-scratched as well. Horrible packaging on the frame rails. That and the lack of extra hardware are really my only major gripes about this otherwise awesome kit.

Does Traxxas offer the slipper pads separately or are you using another brand for the 45T spurt?

Anti-seize is messy stuff. It's not something I ever want on my RC bench. :lmao: I'm still wondering how it looks after mud and water. You'll have to keep us posted. But I think somewhere else you said you stick to the dry.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Nice build thread! Very detailed and informative. Who needs a manual when you have Soze!

It's great to see all the Sport Kit builds going on at the same time. Kinda makes me want to buy another and join in.

I really enjoy watching your build on YouTube. Looking forward to the next.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Unfortunately you need the whole rebuild kit to get the slipper pad. $11.99

I'm wondering if we can just find the correct material and cut out our own slipper pads. Food for thought.

Yes, I do stick to dry, so wet isn't an issue. I especially stay out of mud. LOL It's bad enough when my son's cleats are caked with mud from a soggy field.... if my RC was caked with mud....

The anti-seize I try to put little on and then spread it. I just need to remember to keep my hands away from the cv joints when handling the truck. Otherwise, so far it hasn't been too messy.



Thanks! I do it just as a way for me to remember what I did and what I was doing. It's nice too that if I come across something to watch out for I can document it so that I can reference later on. If it helps other people, then great! Or it can just be entertainment if I leave the parts where e-clips go flying in all directions... LOL (honestly though e-clips were OK on this kit. not having to build the shocks probably helps too. Some other kits have e-clips in nasty places that are hard to clip on)

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

That's the only thing I found. A slipper pad from something else has to fit - at least you would think. The slipper delete plate is only $12 and I lock mine down tight so maybe that's what I'll do.

You can also go on eBay and get takeoff parts that include the spur with installed slipper pad, etc for less than $12.


It looks like there's a lot of grit in there though.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

About a year and a half later, way overdue for a rebuild, but these have seen plenty of mud/water/sand/saltwater...

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Not really, especially considering what it's been driven through in that time. It's hard to get a good photo of it though. New Sport kit will be here in a few days, all the fancy parts are getting switched from this truck to the new one, I'll get better pics when I disassemble it...

Also, sorry about the mini- thread jack Soze, lol

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Nah man it's still relevant! Since I am using anti-seize on my CVDs and driveshafts.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

in a bind a friend of mine used like cabinet anti slip padding stuff in place of a slipper pad in a brushless 3s powered yeti and its holding really well and is quite impressive haha

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Oh yeah, the dreaded e-clips! I remember building my first Team Associated RC-10 back in the late 80's. That kit is full of them. Surprisingly I did not lose too many.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Section F: Suspension & Driveline

It's continuing to come together!


This part of the build requires these bags.

https://farm8.staticflickr.com/7899/...290c2e7f_b.jpg


Step F1 uses these pre-built shocks. {commercial voice}Just add oil!{/commercial voice}

https://farm8.staticflickr.com/7828/...33435c8b_b.jpg


The only thing you need to assemble in this step is the oil nozzle for the shock oil bottle.

Step F8 parts

RED ALERT! One of the output drives is defective with the slots cut at an angle instead of straight up and down. This caused the driveshaft to bind.

https://farm8.staticflickr.com/7802/...c4985c89_b.jpg

https://farm8.staticflickr.com/7879/...091e4152_b.jpg


Called up Traxxas.
me - "Hey, um... I just bought a TRX4 Sport kit, and one of the parts is defective."
Traxxas - "what part is it, and what's the part number?"
me - "It's the output drive that you can find in part# 8295"
Traxxas - "what's your name and address?"
me - "My name is #####, and my address is #####..."
Traxxas - "ok we'll send one out to you right away"
me - "That's it?"
Traxxas - "That's it!"


Few days later this showed up in the mailbox. Back in business!

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

That's great support from Traxxas!! I don't know if the same would happen in the UK though.

Also bummed as I missed out on a used Sport on ebay last Sunday. They are rare in the UK though.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

It's a bummer the driveshaft was defective, but at least Traxxas was quick to respond.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

This is like seriously a professional level build log/tutorial/walkthrough/etc! Awesome build!

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Such a nice looking kit. Thanks for posting up your build in such detail. You are giving Jato a run for his money in that department.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

This build is still alive!

Section G: Final Chassis Assembly

Coming to the home stretch of this build!


These are the parts for Step G1.

https://live.staticflickr.com/7809/4...2a607ede_b.jpg


Pay attention to the rotation direction for the tires as they are directional. I will not be gluing on the tires and using the wheels even though I think they look decent, because I much prefer using beadlock wheels. I'm going to give these tires a shot first stock, and modded with siping/cutting.

https://live.staticflickr.com/7864/3...7d3a0827_b.jpg


For the rest of this section you will need the "Body Mounting Bag"

These are the parts for step G2

So, I encountered my second issue with this kit. I was missing a 3x10 screw. At this point of the build, I should have 12 total 3x10mm BCS screws. I had 11. This is where Traxxas probably should give some extra hardware in case they miscount.

Putting together the front bumper assembly requires 2 3x10mm and 1 2.6x8mm. Luckily, I had an extra 3x10mm screw that I poached from my GMADE GOM box of parts.


Step G4 Complete.

https://live.staticflickr.com/7871/3...e7200279_b.jpg


Step G5 complete. Eagle eyes will notice that I have the sliders on the wrong sides. Not to worry, they have since been correctly put on the correct sides (left --> right & right --> left).

This completes "Section G: Final Chassis Assembly"!

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Section H: Body Assembly

Let's wrap this build up in stock form and get this thread ready for upgrade and crawling updates.


So, the weather finally warmed up, and I got around to painting the body. I used the following for getting this body done.

Paint:
Tamiya PS-5 Black
Tamiya PS-30 Brilliant Blue
Tamiya PS-23 Gunmetal
Tamiya PS-55 Flat Clear
Plasti-Dip

Masking:
Tamiya 5mm Masking tape for Curves
Frog Tape (for general masking)


Here's the end result for the body.

Here's the Tamiya 5mm Masking tape for Curves that I used.

https://live.staticflickr.com/65535/...cba6aa12_b.jpg


Frog Tape for general masking duties.

You'll need these parts for Section H

https://live.staticflickr.com/65535/...631f2517_b.jpg

These are the parts for step H2.

https://live.staticflickr.com/65535/...3fa6358d_b.jpg

https://live.staticflickr.com/65535/...ec68b77b_b.jpg


I encountered my 3rd Issue with the kit. You'll notice that one 2.5x8mm screw is missing. I should have a total of 10, but I only had 9 left during this stage of the build. Again, wish there was some extra hardware to cover. Luckily, I was able to snag yet another screw from my parts for other trucks.

https://live.staticflickr.com/65535/...08bd9d9f_b.jpg


Eagle eyes will see in that picture above that I used the wrong 3x8mm FCS screws. There are actually 2 styles of 3x8mm screws with that big flat FCS head. One uses 2mm hex driver, the other uses 2.5mm. I will show the differences further below.


I also took this opportunity to add a little sharpie + paint marker detailing to the scale parts. Not a perfect job by any means, but good enough to not look like 1 color plastic bits.

Again, I used the wrong screws on these rotopacks

https://live.staticflickr.com/65535/...5435cab7_b.jpg

https://live.staticflickr.com/65535/...2d5901bb_b.jpg


So getting the final step H6.... I discovered I used the wrong 3x8mm FCS screws for the rotopacks. There are two types of 3x8mm FCS screws included in the kit. One type uses 2mm hex drivers and the other 2.5mm hex drivers. The one with the bigger flat head and 2mm fitting is used for the rotopacks. The rest are for mounting the Expedition cage onto the body.

The top FCS screw is for the rotopacks.

https://live.staticflickr.com/65535/...52b87dff_b.jpg


The right screw is the correct one.

https://live.staticflickr.com/65535/...8ff6fec2_b.jpg


You'll need these parts for step H6

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Great job Soze , very clear detailed pictures and instructions, thankyou "thumbsup" what colour blue is that looked slightly purple in some of the pics?

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Tamiya PS30 Brilliant Blue. The purple hue in some of the pictures is from the extreme "white" light from my LED lamp.

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Really nice job, my man!

Re: Soze rejoices the Traxxas TRX4 Sport Kit
 

Thanks, a little messing around with the tires, slap them on some wheels, and I'm ready to take it out for its maiden run!
