Traxxas TRX4M BUILD - BIG PERFORMANCE GAINS! NEW Long Travel Shocks, Brass Upgrades & More!!
HTML-код
- Опубликовано: 1 янв 2023
- In this episode, I continue to refine the Traxxas TRX4M. I get my hands on a bunch of brass parts to add weight and widen the track. After some disappointing runs, I go back to the drawing board and add new Losi shocks, upgraded chassis kit, and make more body adjustments. The end result was worth the trouble!

Hey I jw I was looking at the hot racing mini b shocks I've been looking at them but wasn't sure they would work as well or if I should just get regular aluminum mini b shocks I was also looking at the hot racing 1/18 dromida shocks they seem different but wasn't sure love the build
do you have a list of all the parts you've put into the bronco to get it to its current state?
Just found crawling & your CH!
Super articulate & comprehensive work my friend!
My Bronco should be here tomorrow so I will be referring to your hood-up vids 😎
After lots of testing I maxed out at 56 degree incline with the stock shocks and springs. The trx4m has a lot of torque twist and I found that putting 4 shock spacers on the rear passenger made it crawl so much better. Might be worth checking out and putting a weak spring in the rear right to combat that torque twist.
56 is impressive! That explains why the stock setup has the spacer pre installed in the rear. I’ll do some tweaking with this in mind 👍🏻
He needs someone else set the shocks up
5:15 that would make a really sick thumbnail! that angle tho!!! cant wait to see all the goodies this truck has this year, i can feel a no expenses spared trx4m build in my future, something about this truck really resonates with me
Man it's so much fun to modify. It's like being in constant discovery mode because everything is so new!
Hello Adam,
Would you consider creating a playlist for all your Trx4m videos?
This would make it a lot easier to navigate the videos and follow the experience of your build.
Thank you!
Yes, I can absolutely do that
680g , there was a definite improvement with the shocks, I think oil filled shocks are the way to go. The main problem I have at this moment is the limitations with the battery 🔋! Awesome video brother !
Thanks! I am so glad I gave the shocks a try. They were the missing link!
814g...I'm the same. Things don't go as planned..then you work it out ..its stressful then you get elation...that's why I love this hobby..that's what makes it so addictive
Great content as always..👊
Totally agree. I was so bummed and then so excited. What a roller-coaster!
3x7 Outdoor did a video where they put heat shrink wrap around the drive shafts to keep the pin and small O-ring in place. Worked for them.
I’ve heard of that before. Will check it out!
Great camera work. Great explanation of things. Great video. Also, im super jealous of of the rock crawling track you have at 5:38, that's awesome.
You did a great job. This is not the kind of build I would be shooting for, but this video is super useful as you have come up with different ideas to approach the tuning.
Thank you! It's been a very fun process!
hi, friend. Your videos inspire me a lot to build my trx4m bronco. That's why I just wanted to thank you for the content.
thank you!
I am in process of building an extended wheelbase trx4m. Will be cutting the front frame arms off for more servo clearance. Losi B shocks are on the way! thanks for proving them out. You're going to need to run rear springs of some sort. I just can't get away without them to reduce the frame twist. My rubber band limiter seems to be most effective when connected to the servo bracket instead of the links. Love to see where this build is heading. I've given up on the factory body. Even after removing the top and windows, it's still crazy heavy.
Interested to hear how your build progresses! What are you using for links? I'm going to be testing a new frame from Furitek you may be very interested in...
@@CapeCrawlers I see they just posted the Bettle for pre-order ;) I'm going for LCG type crawler, so I prefer grasshopper style with full length rails so I can push the upper shock mounts toward the link pivots. I'm going to see how far the factory chassis rails will get me, first. for mocking up, new setup will be factory trx4m rear lower links with custom length uppers to provide appropriate front caster angle. Once I finalize that, I'll likely fab some custom high-clearance links front and rear.
@@ericmyers1306 the Bettle, that's it! I also prefer the grasshopper, but I'm going to give the Bettle a whirl.
From what can see in the video your using rubber bands for your limiters. What size rubber bands have you found work best for the TRX-4M?
90% of the fun is the trial and error after any mods or changes on these trucks for sure!! Congrats on 10k man keep this up, the channel is going to get huge for sure 👍🏻…626 grams
Thank you, and I agree 100%!
That's very true. Once you have the build completed it's a lil sad cuz the journey feels like it's over 😭
Nice little rig you there. I used shrink wrap tubing for that o-ring problem.
Thanks! I think I am going to try the same!
1043 grams great video just ordered the shock extenders for trx4m gonna start there see what happens lol. Look forward too seeing more content on these awesome little trucks.
I’m not usually into foam courses, but yours looks fantastic!
Coming from you that’s a huge compliment! Thank you!
@@CapeCrawlers and I love the lines you created! Very nice!
Those tire wheel combo really does look good. Nice to see the TRX come around with those new shocks. 480grams
The v2.1 setup was a gamechanger!
Watching this while i reassemble mine after some custom body mods and a paint job. Waiting on performance parts to show up.
2lbs 7oz
Nice! What colors did you go with?
Put heat shrink around the rubber rings on the driveshafts. Worked perfect on mine.
I will do that! I've got some lying around and I'll get it on there.
What size heat shrink did you use for your driveshafts?
Great Job,
Amazing channel, I always look forward to your next adventure.
Keep up the great work!
Asplenia.
Thanks for watching!
I'm enjoying your content and seeing the Bronco evolve, I just cut my fenders today and it made a huge difference, I would guess yours weighs 698g.
Glad you’re enjoying it! I love modding a new rig. It’s like the discovery process all over again!
Yet another awesome video with a great setup on another rig! The improvement was awesome to see, after the problems were solved. Those shocks are sweet! The hex extenders are definitely nice, but I think it would be a very worthwhile sacrifice to loose them and keep the wheels and tires.
How are your RCAWD Portals on the Gladiator holding up now? I'm thinking about getting a set!
Also, you should try out some tracks! Your video on it would be super awesome!
My guess for the weight is 907g, with the battery! If I won, I'd get a Mini Komodo for my comp rig!
The portals are doing great! I have broken two axles in the several months that I've owned them, and they've taken some abuse.
@@CapeCrawlers Awesome, thanks!
After doing the budget lift on this thing I found that the axle pins kept popping out on all of them and I lost all the pins. What I did to fix this issues was to put a paper clip thru then wrapped it around the driveshafts where the o-rings would be and I have had an issue since. I’ve just got major binding while driving straight. Drive line angles are too aggressive causing this bind.
Great idea with the paperclip!
Thanks I’m going to experiment with that suspension setup ordered it last night to play with
685g.
I’m super happy with it. Shocks are a little sticky but still amazing!
You can use the shock stand offs from a mini t and it works perfectly with the jorc shock keys.
I’ll have to check that out!
@@CapeCrawlers you'll need a pack of the tiny lock nuts from axial, they come in a 10 back, fit the standoffs, shove standoff through shock key use nut, profit, the biggest plus is the standoffs come with the bushing for the top of the shock. On the lowers I use a cut servo mount bushing and a little heat shrink over the bushing.
Like the test course you built.
Thanks!
556g 🤷🏼. Love your content. Thanks for what you do.
Thanks for watching!
Great video brotha!! I'm thinking about 2.5 lbs
Thank you!
brother the honesty displayed in this video is well earned of my sub and like keep em comin bro and please maintain that transparency we need more of you guys!
Thank you, and I certainly will!
Hello, I am converting my FCX24 K5 Blazer to the TRX4M axles. Reason being that the FCX24 seems to be a bit bigger than the normal 1/24 scale and the TRX4M axles are only slightly bigger than the stock axles FMS gives you. Only problem is hardware. Could you recommend me to somewhere i can get the hardware you used for your suspension and linkage?
nice job
I think this is the coolest video idea I think you should put a fpv cam on a scx24 and drive it around or any rock crawler
Oh man, that is a great idea! An fpv course run would be epic!!
@@CapeCrawlers yea I saw some fpv videos and they looked fun
Congrats on having a very capable trx4m. I can't get mine to perform as well as my scx24. I'm guessing 791 grams. Also thank you for having a real 5th wheel on the back. Cant stand to see that fake wheel cover.
Thank you! It’s very capable, but still not quite as capable as the scx24 (yet).
How did u manage to get a full drop on the front end? Seems like mine won’t even move haha
I'm guessing 750g! Loving the TRX-4M content!
Glad you are enjoying it! Got lots more coming!
I enjoyed the video!
Glad to hear! Thanks for watching.
What are your shocks called on your ball black build
What are your shocks called on your all black build
742g. Your build is inspiring my bronco build! What part of cape cod do you live? I’m up in eastham, but born and raised in west barnstable. Shout out to centerline hobbies!
Small world! I’m in Hyannis!
Nice! Do you know of any 1/24 or 1/18 crawler comps in our area? I recently sold my fully built scx24, I think I might build another and build the trx to be a very capable trail rig. I also see an fcx24 in my near future
I was looking at the shocks on amazon the Losi ones and I was wondering are you running rear shocks on both the front and back end or running them accordingly?
I'm running rear shocks all around.
What extension arms do you have on suspension I put lift kit but now my wheel base is shorter
750g - If you have 4 pt scales, try to get weight bias to 60/40
Close! I need to invest in a good scale for sure
I love rc rock crawlers there so cool
Same here!
Yay
awesome build! I'm going 758 grams
Thank you!
Another awesome Video Adam!
Curious if you have a video on possible issues to experience with the scx24 mods? I recently purchased 3 of them so i can wheel with my kiddos. I bought links, trans, servo, axles and gears for my gladiator scx24 but Since i did the build my truck doesn't work...long storey short, My wheels spin constantly, as soon as i turn it on they start moving, and the rig doesn't go very fast anymore, not sure what i did wrong??? maybe i tightened the trans to much? wheels are lose enough i believe, but i do have aftermarket bead-locks, but not sure why the wheels move forward constantly. Any help would be greatly appreciated 🙂
That's a good idea: pitfalls of upgrades! Your issue sounds like an electrical one of some sort. Possibly the transmitter and the throttle settings? Have you tried messing with the throttle adjustments? It could be a faulty ESC also. Sometimes they glitch out after adding new electronics or heavier/more demanding upgrades.
@@CapeCrawlers Ow really? I never considered it might be the ESC, I tried adjusting all the throttle setting manually, but it didn't help, I thought possibly i put the cable into the ESC upside down, that didn't help either, looks like I'll have to buy a new ESC, do you have any you recommendations? or just the stock ESC?
Love the content! I’m going to guess it weighs 875g!!
Thanks for watching!
I think people get way too carried away with all the brass, like anything else is a balance. Yeah you might have more weight for traction but now you're dragging twice the weight up a hill.
Very true! There is certainly a point of diminishing returns
Tried one out today myself and gotta say, the plastic pieces make for an extremely weight body which causes it to keep flipping. IMO the brass will definitely help from flipping and help out more traction down to the tires
Definitely best to shed weight up high instead of adding weight down low
Axle housing weight and lower link weight. Shock bottoms weighted.
Then it’s all about those foams/tires combination. .
The most common mistake is heavy wheels, which is rotational weight and is no good when the right shocks are mounted correctly.
@@dustin6828 well said, thank you
Hey guys I've upgraded my trx4m with the losi mini t shocks.. installed flex blades and shock keys also installed aluminum beadlock wheels and 62mm tires. I have lots of articulation on the rear axle but hardly any on the front axle. Also the front flex blades will not drop and I'm getting torque flex in the chassis. How can I fix these two problems?
I ran into this with mine. Try experimenting with different shock mounting positions up front. Also make sure that your shock body isn't too tight against the frame rails. That was my problem: the shock couldn't pivot on the hardware and would stick.
I watched most of your trx4m videos but how exactly realised you that track width?
The width comes from the Treal hex extensions and the Injora +2mm axles.
I've noticed you are not running the 5 (lug) bolts on your injora wheels. Were these a fitment issue? Also, I'm guessing it is 819 grams!
Before I put the hex extensions on I couldnt get the Traxxas wheel nut tightened with those inner screws installed on the wheels. But the Treal hexes use a smaller nut, so I will likely put them back on. Not sure though as I kinda like the all black/gold center.
made a mini monster truck using the mini b shocks. I popped the ball out of the bottom link and drilled it out.
Sounds awesome! Those are nice shocks!
Do you upgrade front drive shaft at all? Got the new shocks and it seems to bind a bit
I replaced it with the steel Traxxas unit, but that's it.
Cape could you give me a part list for all the things u used on this
Hi. How do you feel weight on the rear axle? Noticed you had x4 Treal 10mm hex (heavy) extensions. Did you end up putting any on the rear?
I have the brass diff cover in the rear and the heavy hexes in the rear. It feels good! Pretty well balanced and super planted. It is awfully heavy though. I'm glad I have the brushless motor!
@@CapeCrawlers ok sweet! I’ve just installed the treal axle weights but just normal injora 10mm hex. Get out for a test this weekend. 810g at the moment, low range and metal diff gears but all on standard electronics! 😱
Thanks for reply👍
My son is upgrading his tires as well to the rock terrain injora bead lock tire he’s having trouble getting the rims to hook properly in the tires could you make a little tutorial on how to put them on properly?
I have a couple videos on this. Check this one out at the 29 min mark: ruclips.net/video/dDu87SwVwpY/видео.htmlsi=uKZxjMxL6UO2cd_Y
Looks good , bust out the Dremel and no more tire rub
Plastic surgery time!
Im just getting into the rc crawler space, would you recommend this car stock as a good starter vehichle to dink around with?
Yes, absolutely. It's a great starter rig! Easy to use, fun, and capable.
I wanna see a comparison between this Bronco & Axial's 24 Bronco, performance wise. 🤔 Traxxas' looks cool, but Axial's looks you could do WAY more than Traxxas', on this 24 scale. If I were to get another 24, I'd probably go Axial.
I did a stock for stock comparison video a while back. I am going to do a modified version soon!
@@CapeCrawlers Sweet!
What shocks and axles are you using ? Are you also using flex blades ?
Axles are stock housing. I added the +2mm injora axles and treal hex extensions. Shocks are Losi mini B rear shocks all around (amzn.to/3EWsRiV) with Adaptiv3 Designs (etsy) flex extensions.
648 grams..I feel like it should weigh like 7 pounds lol it just looks crazy heavy.. but it's a sweet build!
Haha! She’s hefty!!
My son was wondering how much money you spent on your trx4m in upgrades not including the car? My son loves your videos and is trying to upgrade his own
I'm new to this . Have been trying to figure out a wider stands. What Tmrim and tire combo is that?
This is the Injora brass beadlock wheel and 64mm rock terrain tire combo.
Thank you. Ps The Brazilian steakhouse in your town is so good.lol
Any tips on bleeding the shocks and how much oil ? I removed a lot of oil and they where really sticky so I added some and still sticky so I’ve gone back to using the springs but I get no drop any tips ?
Here's a video on bleeding (towards the end): ruclips.net/video/OH_vloPzHvY/видео.html
I used 4-7 drops of oil, not much at all. I rely on the wheels and axles to pull them down. They stick when I first pick it up after not using it for a while but after they're worked a bit they are nice and smooth.
Thanks man I appreciate it I tried finding a specific video and did not see that one
Have you drilled the pistons at all or just stock TLR piston?
No drilling, still stock pistons
Are the losi shocks a direct fit or were there any issues installing them?
I had to punch out the pivot hardware and run a bolt through the empty mounting holes. The shocks pivot on the bolts, which isn’t ideal, but it works. Otherwise it was easy!
2 pound approximately :)
What size shrink tubing is used for going over the driveshaft joint pin and o ring?
I’ll have to check and let you know. A subscriber made some for me but I can’t tell what size the tubing is
1/2 inch if you run them over the o rings. 3/8 inch if you remove the o ring and decide to use just the shrink tube. Personally I just put 1/2 inch over my O rings to be extra safe.
Gonna guess 886G. Considering I am doing a very similar build and have already been adding the weight of my parts together.
You got the closest Chance! True weight is 888g. You got within 2g without going over. Shoot me an email so I can get your info for the gift card!
Thanks so much! Glad to see my math was actually pretty accurate considering I added weight of all the parts from weight of the stock truck. Thanks for your generosity and excited to see how this truck comes out in future as more parts are released.
I'm gonna say this looks like articulation for the sake of articulation without understanding what suspension does. You need to have a close look at weight distribution and how much total weight you've added. Added torque wants to be planted and properly balanced. In addition torque twisting needs to be addressed with that weight distribution.
Just having the wheels touch the ground doesn't help if the torque is going to the wrong wheel(s).
This is meant as constructive criticism, I really like the videos. 😎
You are absolutely right: articulation for the sake of articulation. Just plain fun. I fell in love with tinkering these little things chasing the articulation, so it's almost my default approach to see how much articulation I can get out of these things.
713g? 🤞
Should I buy one of these and upgrade or keep my jlu and upgrade it. I guess my real question is could a Scx24 fully upgraded keep up with your trx4m build.
A fully upgraded SCX24 will outperform the M, or that's how it is with my SCX24's. The bronco and JLU would be close, but the others are unquestionably more capable than the M.
@@CapeCrawlers okay thanks
@@CapeCrawlers hey btw is there a way I can make the jlu have the same wheel base as the gladiator?
Just subbed to this channel? Great content. Hope I made you closer to 100,000k!
Thank you! We JUST now got it!!
Where did you get the shock mounts? Heard you say the name but can’t find them anywhere! Maybe I’m spelling it wrong! Drop a link!
Flubberstufferz 👍🏻
@@CapeCrawlers darn they must be outta stock! Definitely wanna relocate the shocks for sure. Why I love my Scx24 much easier!
can you may publish the STL file for the shock mount?
I didnt make them myself or I would. I got them from Jo RC's design on Etsy.
You defiantly succeeded in making it more expensive.
I’m good at that!
@@CapeCrawlers so many ppl quit the hobby cause they can’t play the money game.
Do u think the rcawd shocks would go good with the trx4m?
I think they would be too short. There wouldnt be much of an advantage over stock. They may even be shorter actually.
Flex blades seem pretty cool and all but when there’s a kids making them off a 3-D printer and only cost like five or $.10 to make . He slangs them for nine dollars for 2+ shipping you’re looking at like 30 dollars for 4 little pieces of plastic . I’ll probably just wait until someone makes aluminum ones!!
Check out Mofo RC, he's got aluminum ones
im gonna go big and say 1105 grams. also, what oil are you running in the losi shocks?
You overshot! I’m running traxxas 20wt.
Great video 1.5 LBS
Thanks for watching!
What’s your tire and rim combo also?
These are the Injora brass beadlocks and new 64mm rock terrain tires
I’ve run into an issue the trx4m won’t climb after new brass wheel’s install just stops when going vertical
Stock gears? You may be overwhelming the drive train if the wheels are too heavy.
Where did he get those tires?
It has to much torque twist in both versions i think itll perform way better without that body roll
What do you think would solve it? Stiffen the shocks?
Nice upgrades and nice truck!
Do you have a preference in using the SCX24 or the TRX4-M?
I'm glad you solved the brightness issue on your videos. Was it in settings? 👍
I still prefer the scx24 only because I have more options for body styles and more articulation in my rigs. But the traxxas is closing that gap rapidly! For the brightness settings, I switched to the Moment app to record my videos. It allows me to customize the lighting much more than the iPhone standard software
@@CapeCrawlers The brightness issue is gone, so that app worked like a charm! 👍
Did I miss the shocks? Or are they just the mini 2 shocks?
You got it: mini B rears all around
Do you have an issue with your front upper links hitting the bottom of your servo not allowing it to flex to its full potential
I’ve not noticed that but you’ve got me curious now. I’ll take a look to see if that’s happening!
It’s been a constant issue from stock link to upgraded links to servo tray. I can see the links hitting the very bottom of the servo on the furthest back edge
What shocks are those
im also from cape cod, i live in harwich. where do you go crawling on cape? Lets Crawl sometime
Aye I am in Hyannis! I like to go to a spot behind BJ's in Hyannis or behind the Coca Cola bottling plant in Sandwich.
Get rid of that rear spare. Get yourself a 3D front bumper. I have one and it never interferes with the front tires. It is about an inch long, dead center of the front of the truck...
Lots of articulation isn't always a good thing.
Very true!
836grams for the weight🤘🏻
i have the trx4m 150 ranger model would these parts work on that, i didnt even know there were different versions or is it just diffrent bodies
Some of them will. Just remember the rear links and drive shaft are longer on the Ranger, so those aren’t compatible with the bronco parts
@@CapeCrawlers cool thanks for the reply, i just dropped about 250 in parts from watching your videos everything should be here this weekend
On your old set up how did you let your front links move up and down fully? I've got the Injora high clearance links and a Injora 11kg servo and I tried replicating your old setup but it seems like the shocks won't extend all the way, I really wanna save this and hope not to buy another Chassis
@CapeCrawlers Help would be appreciated.
The servo mount is always going to limit your vertical axle drop. There isn’t really a way around that. You can articulate really well side to side with an aftermarket chassis and/or a laydown servo mount, but the upper link mounting on the front will always hold you back
@@CapeCrawlers Okay thanks for the help!
Where can I get those tires and rims like yours?
Here are the tires: amzn.to/3lJn368
Here are the wheels: amzn.to/3LOPHNX
That flex is extreme. I have found out that extreme flex will cause the vehicle to downgrade. Stock shocks will work better.
You are correct. It takes a TON of work to maintain capability with articulation. But that's part of the fun!
@@CapeCrawlers Absolutely! Love it.
What size hex is the tr4m
What oil weight are you using ? going to try that trick
Traxxas 20wt
Thanks, just ordered them waiting on the carbon fiber frame rails .
590g
Is there any crawlers out there with chassis options like the SCX24? I really enjoy the stock stuff but I also like the full custom built stuff with every option selected by the builder. I really love the full comp builds, rear steer, etc. I started on the 1/24 stuff and now im starting to looking more at the 1/10 and 1/8 stuff
Furitek has a grasshopper chassis for trx4m and I'm sure that's just the beginning lol
I agree with the above. Furitek grasshopper is available for the FCX24 and TRX4M. I would expect Injora and others to start releasing LCG chassis options for the FCX and the Traxxas soon.
Gonna take a guess and say 850g looks heavy :)
You were close! 888g
hello mate where do u get the stands and what do i type in to search these look awsome
I get them from Gazoo RC on Etsy
Thanks for the replie mate 👍
