7 Best Cheap Mods and Simple Traxxas TRX-4 Upgrades

[@timohungenberg5276]

@Rc Review I just got my TRX4 Sport 2 Weeks ago. What i did so far: 1. I use Louise Champ tires 120x45 with Aluminium Beadlocks 2. i did brass portalcovers 3. i go for an Hobbywing Quicrun fusion 2in1 1800Kv 4. I remove the Expetion Pack 5. i changed the Rocksliders 6. i Turned the front and rear bumber holders, upside down 7. i put 3 onze lead on each tire In total my Sport is about 8.3 Pounds weight and it performs awesome. I do some heavy technical Rock Trails and I love it. Btw ur Vidz just helped me a lot, and love to watch em. Keep up the good work. Greetings from Germany

[@bradcrowdis7926]

Thanks for all the tips, I purchased the traxxas 79 bronco last x-mas, so far its been a fun project, I have done alot of the mods you have mentioned , Brass portal covers on all four wheels and brass diff covers gives me great traction, some pro-line gummy tires helped alot .The better servo is very effective and steering is a stronger feel, two mods that are effective that are not mentioned that worked really well were 1 - change the pinion on the motor to a 9 tooth, it helps to make the motor work more efficiently with wieghts and bigger tires ,less overheating .2 -reconfiguring the control so that the rear diffs lock before the front ,that way you can have posi on the back and open diffs on the front for tight steering downhill. Thanks for the tips I hope these are worth mentioning.

[@marcochavanne]

Francis, you're a bad influence. We have 2 Gen 8s, a TRX4 Bronco, a TRX6, 2 SCX24s, and I ordered a TRX4 Sport last night because I was up watching your videos lol

[@truckerrespect7797]

Thanks for the video, I used to be into this back years ago, I bought the TRX 4 2 days ago and I really appreciate the video. I’m blown away by the tech advances in the last 15 years. I love mine so far but have already started upgrades

[@nilzmoto6238]

Great list and great channel! A couple of other things I've found helpful on my trx-4 sport: Installing reversed 100mm shocks with the black plastic spacers removed, taller shock towers and soft springs with a small amount of oil in the very bottom of the reservoir to keep the seals lubed and add a bit of damping at the bottom of the stroke. This setup is nice because it adds a lot of droop without raising the overall ride height much. Flipping the shocks also lowers the CG a little and you can loosen the shaft seal caps farther without them leaking. Broke the front axle shaft at the joint in a tumble so I installed the HD version along with the MIP 4mm wide track kit. After trimming the fenders it works well and seems to side-hill better without looking too goofy. I also use a small saddle pack battery setup because it allows me to move the batteries lower and farther forward than the bowhouse unit. This also frees up space to mount the esc and reciever on a custom tray that sits between the frame rails right above the rear driveshaft. It all seems to work pretty well and doesn't bind even without the long travel links. Still on stock wheels and tires though and the only brass I have is the ssd portal covers. Recommendations for tire/foam/beadlock wheels would be much appreciated. I run on rocks and dirt but not much deep mud. I also run in the wet a lot. Thanks!

[@dominiqueleblanc2193]

This is my first and only rc. It's stock and I love it. Bead locks are on the way.

[@jnsfrahm]

I'm new to crawlers so I took your advice and purchased the Traxxas TRX-4 Sport with the above upgrades. I'm sure this is just the first of many new trucks to come. Thanks for all your honest and insightful reviews.

[@loum7008]

Thanks for all the great advice!!! My 2 recommendations are to skip the steel sliders and shim up the stock one. The steel was too heavy in New England and when side hilling the truck would slide down the hill. The other is to much more highly recommend overdrive. I've done front and rear and it's amazing. Trailing is fine, I'm not going super fast but that's not what the trx for is about. On that note, trx4 is not for high speed. 20mph is fun until you drive any other category vehicle. "Thanks a ton" love that!!!

[@dezfan]

A TRX4 Sport Kit will be my winter project. 👍🏼

[@douglaselliott8298]

I've had my TRX4-Sport for two months and love it like one loves a wonderfully obedient pet. I purchased it RTR and accessories so far have been the expedition rack, grill-headlight lenses and tailgate panel/lenses. I'm somewhat a recluse, I don't compete, and there is no 'Climbing' to speak of at my home's desert-scape rock garden necessitating the otherwise very attractive brass weighted portal covers. The Traxxas 'TRA2250' servo with 330in/lbs is, however, atop my wishlist of future upgrades.

[@rodrowdy6661]

Can't wait for my Blue sport next week. Your videos are holding me over :). I recently got back into RC , looks like a great time for them. So many new trucks and cars with amazing designs and tech.

[@RCReviewChannel]

Our story is the same as you. TRX-4 got us back in.

[@Guy-em4ck]

Hello. I love your channel. I like your style of reviewing. I didn’t really care that much about crawling a few months ago but after watching and listening to your reviews I’m starting to get it. Might pick up a TRX4 Sport in the near future. One question: ofc covering crawlers is cool and all but do you think in the future you might start reviewing other type of cars? On road, drift, F1, buggy, sand rail, short course, etc? Would love to hear your take on those types and brands. Huge fan. Take care.

[@Pauly5150]

Really informative. This has helped me decide to get one.

[@jslots2]

I got the esc coming wensday , beadlock wheels and tires, with a savor sw-0230mg servo and stock motor with overdrive gears and, aluminum portal covers in the front..

[@stevebracewell9675]

My sport in stock form out performs some of the high dollar trucks in the group I crawl with,also like the red cat gen 8.

[@Nickeeefy]

If u dont have the money to buy new tyres you can modify the traxxas stock ones. They are really good modified. Cut the small center lugs and every second of the big lugs also u can try dremmel the lugs so you make tracks in them to soften them up. But you need to replace the foams to dualstage ones that is really important if you want to crawl. Also a cheap way is to buy tyre weights and put them either on the bedlock ring if you have bedlock rims or around the portal house. Try glue with zipp band should work until you have the money for real brass weights.

[@ezekielmalachi5405]

I just subscribed to your channel…Truly honest review and sharing of your knowledge. Just bought my TrX4 last week based on your reviews. Loving my TrX4 😊👍🏽. Thank you.

[@jamesmorrell2901]

While waiting for my TRX-4 Defender to arrive I watched this video to get an idea of what upgrades RC Review suggests. When the Defender arrived a week ago I immediately replaced the weak stock servo with a 25kg servo and put on a set of aluminum bead lock wheels mounted with Vanquish VXT tires. Rather than replace the stock ESC I decided to go brushless, and yesterday I installed a Hobbywing Fusion 1800kv motor/ESC combination. This morning I added the SSD brass portal covers to the front axle. I will probably replace the stock sliders and go with a low CG battery tray when my wallet recovers from the mods I've already installed. I do primarily trail running, so I won't be using overdrive gears.

[@montesamapping]

Great as usual ! In our experience, the most important things are (in this order): - tires and foam (60%) - shocks and suspension calibration (20%) - battery position (10%, only considering central or front position, back is awful) - some frontal weight (only in some models, but battery in front is better than add weight to move in every situation) - bumpers adjust or removal (10%}

[@Evan_Moore61]

I have a TRX4 Sport (I’ve been into crawling for one year tomorrow) and a TRX4 Kit. I did the tire mod you showed us, and I’m fabricating my own lcg battery trays out of 0.02” aluminum. I ditched the ugly and huge bumpers from the kit, and added the Sport bumpers to it, and threw on a winch bumper from RC4WD and a custom tube bumper on the Sport. I have more mod ideas coming, I just need to get out into the shop and make them happen.

[@jamesdoughty1522]

The Best upgrade I did to my TRX-4 was 2.2 beadlocks and the RC4WD Iroks. A lot of cutting to fit without a lift.

[@briansrcadventures1316]

A very informative video! I've recently bought a TRX4 Sport kit. Pretty much as stock at the moment, apart from Amazon alloy beadlocks, hair buns in the tyres, a Hobbywing 1080 ESC & a Amazon 35kg servo (running at 7.4v). TX & RX is a Flysky GT5 (a bit overkill, but at least plenty of spare channels for lights etc).

[@mikeforever7702]

Thanks for your time and effort sharing your experiences. I am a novice within the hobby and it looks like the Traxxis sport is a great entry point for me above and beyond toy store vehicles. With your suggested modifications I can maximize the fun without wasting money on marginal upgrades. It seems tires/wheels, esc, and servo will have the greatest impact. Am I correct?

[@mikehashobbies3087]

I love your videos! They are super informative and you are my favorite for anything RC Crawler!

[@billderas3420]

For my climbing needs, I pulled the Bowhouse battery tray and went with the Traxxas inner fenders #8080 which places the battery in the front. Thought we had already agreed this was the best battery placement...LOL

[@RCReviewChannel]

It's pretty good but the battery sits pretty high and affects CG. Heavier wheels and portals and a low battery works much better for us.

[@SebastianLong]

I recommend getting wider wheel hexs as well. 8-9 mm hexs seem to work best. The suspension can still flex to it's limits, but still gives you a little bit of width to make it more stable. I run 8 mm brass hexs I found on eBay. Matched up with my aluminum bead lock wheels, it's a night and day difference.

[@Midlifecrisismods]

I just wanted to thank you for being so personable with your audience and informative. You saved me quite a bit of money in The crawling hobby; As I would have exhausted quite a bit of money with trial and error. I'm getting a smaller battery I'm going to change the servo, (trx4 79 Bronco) move the battery forward on the front. Invest in some wheel weights play around with those. Most importantly get some 15 weight shock oil. My Hyrax tires come in today. I really your videos. Keep em coming

[@ericpeterson9676]

Also I got the adjustable aluminum shock tower. With the longer wheelbase kit..

[@severynmuzychko3730]

It is my first and i love it im planing on doing some upgrades you have recommended

[@micaelacarter4971]

Have you tried the pen spring mod in the trx4 sport? Stops the front springs from unloading when climbing. Also improves sidehilling 👍

[@chess135]

love my trx4 defender. almost all mods are there, exept the battery tray, no need for trailing with kids. thx for awesome channel.

[@sheldoniusSRSlider]

automotive wheel weights in front and rear tires. my stock front high trail wheels are 350 grams each. 320 in rears. I used heavy duty battery terminals for extra weight mounted behind front bumper support. next im gonna get some scale accessories before new servo, 1080 I like that idea. also I like stock motor, its faster that fusion pro

[@SoTwissted]

Ok one of the best you past over when pulling the bumpers flip the bumper mounts!

[@RCReviewChannel]

That is a good one! Free mod!!!

[@leandrolopes4777]

Hi loved the vídeo i have just one question, whats better: lift the sliders or remove them? Thx 😁

[@vansantsam]

Adding weight (even down low) can be tricky.. You really only gain with climbing, downhill may be worse and traversing across could be worse (puts too much weight on the sidewalls and causes them to fold under making things worse).. In my opinion the best way to add weight is to seal the vent in the tires (air tight), take out the foam, and add about 1.5 ounces of lead shot or BB's inside the tires (all the weight is pressing the tire against the ground).. It is a crawler and won't have adverse effects on tire balance, as the shot or BB's will roll freely inside the tire..

[@traxxasJohn]

Your wheels and tires are the lowest point on the truck, so adding weight here gives the weight you do add more leverage. To add weight I went with gear head aluminium beadlock wheels. They look great, and add weight as low as possible.

[@earlhamil731]

I bought the TRX-4 to mount the killerbody gladiator. No bueno. Couldn’t make it come close. So I scored a defender body, added latest lighting and I guess next might be different wheels. Building a Mercury chassis and it’s a tragedy compared to the TRX-4. Agonizing build. Not quite there yet.

[@michaeldorich4485]

I am new to r/c crawling and I have a used TRX4 Sport. I found this older video which is very helpful. In this you mention that you have the Traxxas beadlocks and the Proline Hyrax tires and inner foams. Do you have any trouble fitting the Prolines on the Traxxas wheels. Some of the Proline short course tires only work well with Proline headlock wheels. Do you recommend any of the cheaper all aluminum wheels for the Hyrax? Thanks.

[@greggk1061]

So clear and concise. Like the before and after videos too. Want more of that for each mod.

[@ChrisHirner]

Was real happy with the limitations that the scale bumpers and rack on the trx4 defender body, til i got some good tires and wheels. Then all the scale stuff slowly went away. got some ssd low profile bumpers and really dont miss the roof rack and spare. now i have a hard time finding anything i cant get over.

[@tomcook5813]

Are there heavier servos that might help lower the CG?

[@LeftenantMalachi]

The 20kg amazon servo seems to be less twitchy with the 6.0v on the Hobbywing better than the 7.4v option. I'm guessing the higher voltage would work better on say a Savox unit.

[@RCReviewChannel]

great feedback

[@andyb9994]

I would agree with your upgrades, I have a TRX blazer and a TRX sport with traxx and tires, but love both, I lifted the blazer and was not good for crawling, still better than some crawlers.but not as good as it was, but weighted the wheels and stuff like you had in your 7 mods and it helped a ton even with the lift...the sport is stock and is amazing but will get some upgrades.👍👍

[@RCReviewChannel]

Right on. Thank you for the real world experience share.

Do you have a video setting up the suspension for the sport? I'm having hard time setting it as it sit too low and the rebounce is weak even I'm using 17.5w shock oil and pre-load the spring halfway down.

The X4 is a highly capable crawler. My friend and I place top three regularly in local comps. You must do EVERYTHING you can to lower the CG of the truck for comps. Depending on how much you want to win will determine how much you are willing to do to get the CG down. Good luck!

I’d go with skid plates over the sliders rights off. The factory plastic sliders will wear but that’s better that’s your differentials getting gouged. I learned that the hard way.

[@maratbaspak4517]

From what I have heard so far the foam inside of the wheels absorbs water like crazy thus adding some weight after driving through deep waters. Is that the case for all crawlers? This might be an additional load for steering mechanism of the truck, don't you think?

[@tomasmartinez3936]

Correct! They also almost never dry, best thing to do is seal up holes in the rims and if you have headlocks they’ll be waterproof. You can then run the tires with foams or without, I run without foams and used a gasket maker to seal the rims

Battery mount for sure. Needs to be lower, smaller and more forward. Need much, much better bumpers front and rear. And need high performance, low-weight bodies that look good. A lighter, much more controllable, higher turn motor is a good idea. Really need better wheels and tires and foam.

I think that the OD/UD gears are only necessary for crawling and not for trailing. Modified Canyon Trail tires are IMO better in most cases/terrains than the Hyrax. For both trailing and crawling, lower the CG of the truck as much as possible. For the crawlers out there: 45/9, soft suspension, 62f/38r, and radical weight reduction everywhere. Low and slow!
