I bought myself a TRX4 Sport, myself, for my first crawler. I'm usually a high speed basher type, but after buying this, I understand why people enjoy crawlers. I really get it. That thing, even right out of the box, blew away my expectations. I drove it through a local creek with a waterfall and huge rocks. Don't ask me how, but I managed to scale that waterfall, along with the giant rocks at the top. Second crawler run with a crawler.
I flipped my bumper mounts, cut off the trailer hitch, raised my body 1/2 inch, raised running boards with 14mm spacers (no need to cut body), body is so light that top heavy is minimal.. Mostly all free (except for 14mm aluminum spacers).. Am satisfied. goal was free or cheap improvements for a more capable trail rig (not trying to make a mountain goat out of it)..
Which 14mm spacers did you use for the running boards? Also what did you use to raise the body 1/2”? Thanks
I dont know of this is a thing others do but on metal rock sliders, put skate board wax on them, makes them slide like butter on a hot pan super slippery and you dont get hung up
Your recommendations are certainly going to make my first crawler, and kit, the best experience. Thank You.
LOVE the Slider Mod! If I can EVER afford a TRX-4 Sport Kit... That's my first mod, with the Body cuts. The Proof is how WELL yours performs!! 👍👍
I've used Holmes Hobbies Motors for years. Won't use anything else! They're just that good. 😊

I have never owned an RC vehicle, (only a couple drones), I watched many of your videos and it came down to the Gen8, Sendero, TRX-4 and decided on the TRX-4, because I think right out of the box there are less concerns (or weak points) that might need addressing.. 1st probably would be the servo but other than that, it should be good to go for most applications.. Most everyone has the red or blue so I decided to go with the tan and am going to put a big tiger face sticker on the hood.. lol..
Post a vid of your truck sir I would love to see it 👍
Please tell me which mounts and screws you use for the RC4WD Sliders - Cant find anything. Thanks!
It's looking much better, dude! 😃
Great job upgrading it!
thank you.
Just bought one this morning, good to see how to improve it’s crawling abilities
Minus the HH Pro, this is my exact set up (use a protek 4100 battery too). Good stuff man.
Think it's funny how many people say brass is not needed, but then like to talk a about the winch set up they've come up with or whatever.
I really enjoy the TRX 4 stuff your showing. I come from old RC-10 T1 racing and 20 years real life rock crawling with big 2 door Jeeps.NO 4 doors.I'm trying to keep from doing too many body mods being that I purchased mine for the scale Blazer body. But I did keep up to a stock Axial RR 10 Bomber on the trails yesterday so my set up and weight distribution must be right. Please it's not Actuation it is" Articulation " keep up the good work
Articulation indeed!
LCG battery traybis the most important mod for this awesome truck. Inlove it and I am glad I got the sport unit…
mounting battery in the front performs better
THANK YOU!!!! OMG THE LITTLE BALLS WORK PERFECTLY TO LIFT MY SIDE RAILS!! THANK YOU AS ALWAYS
right on.
Very nice good video and info. Thank you for sharing you are my number one go to for honesty and you have the best tips and tricks
Right on. Appreciate the kind words.
I cut an inch off the rear section of the chassis rails that don't do anything. Then cut an inch out the back of the body and riveted on the original rear end in. Allows much steeper climb angles
I'm forced give the instant Zeek Award of Excellence to the RC Review Channel for the use of spare parts to achieve the desired result.
I can see Subscribing was not in vain.
I’ve done most of what you have to my sport only I took the battery tray out all together moved all the electronics to the driver side and the battery to the pass side o and I cut the battery tray where it bolts to the trans the 1080esc fit there perfect also the front over drive/rear under drive increased my climbing ability by 10 degrees
So good huh?
that guy can you show a pic
Trevor Penfold I will try and figure out how to post a pic on here after work today
I took pictures but dint think I can reply with them any help if you can would be awesome
I like the green color you guys went with.
Yes!!!
Excellent test! Love that setup👍👍
This is our keeper.
Man you are busy making videos!..thanks!
On vacation from the day job so it's good to explore how this channel can grow if I devoted more time to it.
Cheers for all the great videos - especially the ones on the TRX4 sport (got one myself recently and have already made most upgrades and mods that you suggest). On, for example, the Axial Capra the front tyres take the first impact (instead of bumper and body on the TRX4 sport), which I believe is an advantage in some situations when it's hard to come in at an angle with front/right tyre. What are your thoughts on this?
Thank you, I learn a lot from you
Right on. Saving folks time and money through our struggles. :)
Hi im new to crawlers but got a question for you. What's the difference between a crawler and a trail truck? Would the trx 4 sport be a good trail truck as well? I want to get the tan model. Thanks
Thank you for sharing, always can count on great tips, trucks and ideas😎🙏🏜 appreciate you brother. Any special gearing with the motor?
Can someone please tell me the exact motor model here, the link just takes me to the page with a bunch of motors
First of thanks for all the videos, I just bought the trx4 sport kit and appreciate the info and testing you do. What battery should I get I ordered the hobbywing 1080 esc, got a Holmes hobbies motor and good servo.. 3s or 4s? And how big? Thanks again.
Welcome to the hobby my friend what did you end up going with
Thanks for the tips. Took my son to play at LVP yesterday, there was some water in the lower section from the recent rain. A lot of challenging lines for a small area.
You're local? That's the stomping grounds of RC Review. We have a San Jose RC Crawlers group on facebook you can join.
@@RCReviewChannel thank you for the recommendation, just got accepted.
Hope to meet you sometime at the park. My wife has the TRX 4 Bronco, now Jeep. I started with the TRX 4 attack vehicle, now 66 Chevy PU, also have the TRX 4 Sport Kit.
Nice thanks for your help awesome car 🚗
Yes, we've tried a ton of mods and wanted to share the ones that deliver!!
my favourite crawler
It is bulletproof. We handed it to a 5-year old kid and it survived.
Mine has decelopped the same squeaky noise from the second ride. Is that coming from the shaft knockles?
Love your TRX-4 Sport Video
Thank you for these and all your other tips. Getting ready to start putting together my Sport kit. What do you recommend/end up with for shock oil weights on the trx4 sport? I am doing pure crawling setup and very little brass, want to keep weight down. I have heard anywhere from 10wt to 35wt.
Omg. The squeak is killing me! :p looks like a good combo. Like it better then axe?
It performs better than the legendary Axe. More low speed and more punch. The issue though is this wears out over tim and will not take on water and mud.
Just added the bowhouse battery tray and it hits the links reducing travel in the rear suspension. Any recommendations?
what car did you get the shock mounts and screws from the Sport or another car?
Do you run an overdrive up front or underdrive in the back? I’m considering it, but sometimes I just drive the truck around. It’s not always on some ledge trying to pull itself up…
They have exactly the same effect. But I commonly prefer under drive, because that gears down the vehicle a little bit and slows it down. It has the same effect as using a smaller pinion gear.
I am so gonna use that slider mod. Thanks for the look under the hood , 👍👍
Yes, makes a key difference of only making contact when it's really needed.
I’m so glad you take the time to answer and reply . Some youtubers get bigger and then you don’t get any feedback . #1 RC you tube channel. Thanks

Getting a trx 4 sport for Christmas wanna add a little power and speed but not to much for crawling any suggestions and is there anything u have to do before taking them in the water
Do you have issues mounting the Hyrax tires on stamped steel wheels? Which ones work for you?
what shock mounts were used? Thanks!
Has anybody else had trouble programming the 1080? I press the set button and power at same time it starts up I keep in in nutral then press black button again and it stops? I have a gt3b radio please help
What shock mounts did you use to raise the sliders? Can you add a link for those please.
These came from a Redcat Gen7. They were just the right height.
@@RCReviewChannel Try the Vaterra 3x6x12 aluminum spacers from AMain. They fit perfectly and look better than shock mounts.
Hello mate, your channel is starting to be by far one my favourites, I’m treating myself to the trx4 sport kit for Christmas. I was also going to get the hobbywing 1080 esc when reading the manual I though it said the motor turn limit was 16t but you have fitted a 10t, is it still running ok?
Is it possible to do your slider raise with spacers mod on the stock sliders? The RC4WD sliders are on my future upgrades list but want to do the mod now. Thx
Can you Explain why a 10T ? also options are motor rotation forward (clockwise) and Backward (CounterClockwise), Motor timing 0,6,12 degrees
I highly recommend that fender flare mod to everyone that has a TRX4 Sport body. I was sick of hearing the tires rub the body, so I cut the lip off the flares. It doesn’t take away from the looks at all, I personally think it adds to the looks. Are you guys going to do any reviews on the new Spektrum STX3 3-channel radio/receiver combo? It’s a budget system for about $45.00. I’ve got one for my Sport Kit, and for being a budget system it seems to be pretty good.
Exactly right? Drivetrain is so quiet but body rubbing the whole time!!!!! Plus, one can lower the body and the CG!
what about inner fenders with front battery mount?
If you run taller tires on the front vs the rear that would be like an overdrive right?
Hey there, can I run the Savox 1210 with the factory ESC?
I am hoping to avoid BEC and new ESC for now.
u should be able to yes, only not at full power because of the lower voltage the factory esc provides.
Will the stock traxxas controller work with this esc
What happened to the long travel kit? Just about to pull the trigger on that for my trx4 sport then I see this video.
Is the body easy to cut? Do you just use normal scissors?
I am impressed by the metallic green colour. I look for it but could not find. Could you please help and inform which it is?
Awesome !
I have recently built the sport kit. In the video at 5:10, mine didn't crawl like that... What are your suggestion ?
Hola buenas,mi pregunta es sobre el ruido eso q hace al girar motor??
Por que?
No el sonido del variador ni del servo...es cuando coges velocidad relativamente...
Are you still using stock gears?
Damn this rc car is so cool
Rrrright? It's simple but good.
What frequency are you modulating at? I have noticed a difference in sound when changing the frequency with cheap motors.
#5, the highest setting is the quietest.
Awesome videos. I learn a lot!! What was your gearing for this video?
Their is one I found it thankyou so 3
ChiGon! Scale AF👌
Do you no if their is a bind button on the radio for the bangood rgt 1/24 truck my esc went out and I bought a new one and I cannot figure out how to bind them if you can figure it out can you let me no or do a video on it please
Do not know. There has to be though as it looks like a legitimate hobby grade radio.
Were you running a bec for that Savox servo in this video?
Nowhere the esc is running at 7.4
Can't wait to get my 27 turn..
Francis, what do you think of the holmes crawl master 540 magnum 11T?
Great video and I have subbed to your channel
Thank you!
How long is the run time with that battery?
Thanks for your amazing videos! I've learned so many things from you. If you don't mind, would you please share the wheels' brand/model? I loved the low-profile/old-school design of them. Thank you again for your efforts!
These are Gmade Steel wheels.
@@RCReviewChannel Thank you so much! Love from Bay Area 😊
So did you cut the bottom of the body off to move the sliders up?
And not raise the body post?
Where did you get the rock sliders spacers?
The RC4WD Rock sliders you can get from RC4WD in the US and RCBITZ in the UK. The spacers are from linkages or suspension.
What kind of wheels are these?
What brand and size of tires please?
Where did you get the rims ?
Hi. I realy enjoy watching your videos. You've got lot of knowlege and it easy to gain it from your materials due to way you explain things. You've helped me to make the final decision about my rig and it will be trx-4 sport kit obviously which is on its way to me already.
Thanks a lot !
Btw: I don't really want to bother you as I believe you must be a really busy person but I have to ask: what does make that squeky sound in your drive train? Is this something I should be worried about? How to avoid this?
we take the time to research, understand and listen to others so it makes sense in a way folks can relate to it.
@@RCReviewChannel thank you for your reply! But what about my question then? :)
Does this truck have locking Diffs
✌🏻😎🏴Awesome. When will you be modifying those 24 scale crawlers? I waiting in anticipation 🙃
Yes, working on it now.
holmes hobby ! nice..
Love that truck. Have many of your mods on mine. Do you guys do Competition at all? Would be interested in seeing your thoughts on what you would add to make it C1 capable
Don’t compete yet. Need time :)
Boy I understand that 🤣🤣
I talked you yesterday about installing a castle bec in a sport. I am running 3 20kg servos for a v plow. How do I install the bec. Plug power into the red wire on the side of esc then where does the other wire go? I have the dumbo x6 radio and 5/6 channels are used up. Thanks.
Wiring options are crazy for a BEC. The best is something called a y-connector. Others on youtube have done a good job explaining it and we're not expert at it at the moment.
RC Review ok thanks for your time. It’s really confusing. I’ve heard that the stock 1 amp bec could get overloaded and fry my esc and even know I’m not a huge fan of the xl5 hv I don’t want to fry it.
You can’t fry it. The servos will just stall at the limit
RC Review ok I was worried about that. Because some people were saying it in the traxxas forms
Install a short servo extension between your esc and bec.
1 cut the RED wire of the servo extension, so the esc doesn't uses it internal bec anymore. But your wiring is still intact if you want to hook it up on a laptop or something.
2. black and red cables from the BEC you have to solder to your battery plug on the esc( so it becomes direct power from your main lipo.
3. Put them Into a free channel. Don't know which bec you have. Above 10a most of the times have 2 wires going into the TX. There are special Y extensions for BEC.
Here you can see the wiring to the battery connector.ruclips.net/video/UvauQz6HEyQ/видео.html
Thanks for the great information . I know that you built the truck for crawling but how fast is the truck on regular terrain ?
It's about 9 mph with the stock 15t pinion gear of the Sport.
@@RCReviewChannel Thank you for the information , Love your videos
@@RCReviewChannel STOCK pinion of the SPORT / or SPORT KIT is 17t (with 39t spur)
So what is your real gearing ?
Great video! Are the SSD brass portal covers enough weight up front?
Yes, the at is the key! Weighted front wheels are good too if the front is still lifting on the steeps.
@@RCReviewChannel thank you for the quick reply! I learn a a lot from your Channel. Currently building a trx4 sport kit. Should I install overdrive gears out of the gate or just run at stock and see what happens
What rims are those?
What are those wheels and tires
Mega like 👍👍👍
You need to run a 1350 mah 3 cell in the front of the truck. I made a custom mount and it crawls much better
W run that on our Bronco and Defender. On this one, it's not really needed since it's so balanced. Front mounted battery raises the CG a bit.
Don't forget that's a five slot motor
5-slot, indeed. So the turn count translates to higher right?
@@RCReviewChannel I know the 13t 5 slot equates to a 21t 3 slot... Not sure about the 10t.
What springs and shock oil, did you end up using?
Yellow springs rear, white front (stiffer in the rear) 35 wt rear, 30 wt front
@@RCReviewChannel
Great. Thanks for taking your time to answer, it’s much appreciated 👌🏻
@@RCReviewChannel White spring is 0.30 stiffeness and yellow is 0.22 = Yellow is SOFTER , so your set up is SOFTER IN THE REAR . Maybe you did confuse with the box stock kit ORANGE color ?....
holly molly u can`t even hear that motor when is so slow
What park is that
Join San Jose Crawlers on Facebook for the local spots
Any issue sending 7.4v to receiver?
None at all.
@@RCReviewChannel "none at all" ONLY IF YOUR RECEIVER CAN HANDLE 7.4v ... should you precise .
You didnt recommend one of the most important upgrades tires. I will be doing mostly trail crawling as in this video. Mix between dirt,mud and rocks. What all around tire would you suggest for the trx4 Sport? I plan to get metal wheels with beadlocks. I know many like the hyrax predator with dual stage foams for rocks, but is there a better tire that does well in mud and loose dirt as well as rocks?
Tires on the TRX4 are one of the LEAST important upgrade cause box stock ones are excellent polyvalent tires ;)
Just change the foams cause they wear fast and become too soft. / Hair donuts at 1€ piece are fine , cause im not so stupid for buying their f***ing 40€ branded ones.
Why is it squealing so much? Mine just started doing that
The driveshaft’s need oil
@@RCReviewChanneldo you have a video where you show where to put the oil on the drive shaft?
Whoop Number 1
If this was a race, then you've already won.
Thanks, you're are the only videos I watch straight away on RUclips. Best rc channel around!
your missing a lug!
Must find it!

Thank you for the suggestion.
lots of pointless upgrades, bowhouse tray is really a waste of money, also trx4 workd best without any slidders. they hang up alot
These are the upgrades that work for us and we've tried many, many out there. What are your top uprades?
Most of these upgrades are either free or very low cost, and increase ability of the truck so much that you're kinda silly if you don't do them, unless you just like running stock, which is perfectly cool, too.
i personally modified the stock tray, turned it sideways at the lowest point of the middle part of the chassis. chopped up the tray a bit for fitment. it now sit lower and more centered than the stock location. and for sliders i use nothing. the body i use ( honcho cab woth vaterra ascender truggy cage) fits perfectly without sliders. the electronics trays act like sliders and dont stick out as much as sliders do. I have never used a bowhouse personally, but many videos out there show how it does add much more in improving the HCG of the stock tray, made by 1 degree in incline better, not worth the $20 or so dllrs imo, best invested in something else, just my opinion of course. May i add i do love that esc and motor combo you have, cant wait to get me one. 👍👍🤟🏽
@@cali619brown4 how the fuck can you comment and judge parts if you never ran them?!! GTFOH "oh I watched video's and yep its worthless" move the fuck on! It lowers your battery 1 1/2 in the rear and 2 in the front in the front. 1 degree wtf is that?It drops your battery down in the frame rails instead of sitting 3" above everything " lcg" All I got from your post was blah,blah,blah!!😂👎
