TRX4 Brass, can the cheap stuff be any good? Is it really that bad?

- This week on TJsRC, it's time for some cheap TRX4 portal Brass. Our experiment will be, can the cheapest, eBay, front axle, brass portal weights, be any good or even usable? Well let's find out together when I try installing them on Thor, the TRX4 Bronco. We will measure our success by our test subjects ability to climb a highly angled, sloped board before and after installation. That is, assuming the super cheap parts will even install properly, which you shouldn't assume BTW. Follow along and find out what we learned about these super cheap alternatives to their high dollar, much higher quality counterparts.
Also if you wouldn't mind commenting what would you use as a way to test this upgrade? Or what would you recommend for a cheap DIY material for the slope board to have better traction?
Please also consider looking me up on Instagram, @tjsrc where I post related pics. I would love it for you to also follow me over there as well.

Tell me how you would test a weight upgrade like this or what you would use for traction on the ramp. 👊😁
do some quick turns you will know if the truck wants to roll over
Greg Plaka Even with the extra weight down low it's still a top heavy truck for any high speed driving so it'll flip over quite easily. The point of the brass was to help with slow speed crawling. It does help that but not in an overly dramatic way.👍
Grip tape for stairs at any of the big box stores would work better...
@@TheMrZombified That's what I ended up using. Got it in a big roll at Menards. The packaging called it non skid tape or something like that.
id do mine out of stepping stones
Holy moly, any more of an angle you’re going to be straight up dang that thing is awesome
Yeah the front end weight bias makes a big difference vs having it balanced evenly front to back.
Adhesive backed sandpaper,love the video TJ,awesome upgrades👍👍
James Swift Will definitely check out the prices for some cheap sandpaper. Maybe the dollar store will have some. I'm glad you enjoyed the video. 😁👍
Great video, I used a 60 grit sandpaper works awesome for my steepest climbs.
Michal K That's pretty close to what I went with. I ended up using grip tape and it works alright. 👍
Great video, I agree with sand paper comment for a sand stone like grip. Awesome job on the video!
don anthony Thanks I appreciate that. The sand paper could work I will be looking into that. 👍👍
Double sided tape and something we in UK call Deck Tread it's basically a very tough and thick none slip grit board pad , it's used a lot on Boats , Ships and any where theres water under foot stop's shoes from slipping.
Think there's some with a glued self sticking backs peel off sort of thing last for years with what you will use it for
shottonfb That's a good idea. I do believe we have something similar here. Thanks for the suggestion. 👍
I didn’t have to shave, but it was just as tight as you are showing I just put all my screws in and slowly tightened each one, and it slowly faded perfectly
Glad you got it working. 👍
I ordered the cheapest set of weights that go over the outer portal covers for Trx4. They looked good, machining looked good, but they didn't fit out of the package. Same here had to dremel them to slide on. Next had to remove a portion that c ring, it was making contact with the inside of the wheels and binding up. After that they worked great. In the end they started at 75g each and ended up 50g each.
JD'S RC'S Yeah the tolerances on the super cheap stuff is terrible. I'm glad you were able to make it work. Do you normally enjoy modifying stuff for your RC? Or was this more of a necessary evil that you had to endure?
@@TJsRC I enjoy doing mods as I need to. I barely added some weight to my Trx4 a few weeks ago and I think it has helped quite a bit. For me, I like to keep trying until a mod is needed or I break a part. Fortunately I have not needed anything major.
Skateboard Covering like sand paper with a sticky backside...Works Amazing get it at any Skateboard shop or place where they sell Skateboards
That's pretty much the same as what I ended up using.
Also your board was glexing in the middle from the weight of truck that is changing the said angle of the obstacle
That's true it did alter it slightly. But like most CZcams videos this was mostly opinion and barely a scientific test. 😂🤣
Skateboard grip tape can be had fairly cheap on Amazon
I did end up going with something like that. 👍
I got the cheapest brass front bumper mount. Took some filing 👍
Awesome, glad it worked out. I enjoy improvising things in this hobby, I really do but it's also very satisfying when pieces simply fit together the way they are supposed to. lol
Use duratrax deep woods tires and you’ll have more grip. 👍👍
I haven’t tried those yet, I have heard they work pretty good. I switched to the Boom racing Hustler MTX and I’m very pleased with how they’re working out.
I put gorilla grip tape on the ramp I'm really curious though about the affects of weights as an all rounder what goes up must come down how does all that weight affect it's breaking ability when trying to descend a tricky spot cheers mate 👊👍
It's not bad at all as long as you balance the front to back weight ratio. Obviously if you put to much weight to the front it will end over a lot going down hills and obstacles. Also the speed these trucks go is relatively small so the extra mass doesn't affect it negatively unless you have a very weak drag brake setup.
They must had fix the problem since your video they must’ve watched it lol
I'm glad the low budget options are getting better.👍
I got the cheap ones from Amazon and they work great
Nice 👍👍
I don't know if you could call it a test. But, I add weight till it almost flips over on a steep down grade.
rc trailcats Thats not a bad idea. 👍 To much and they'll end over on the downhills, I like that. 👊
Anyone have an issue with the camber changing with the brass c-hub carrier? It seems as though the bottom of the tires are turned in rather than out.
I didn't notice that with mine. Maybe hold the brass piece side by side with the stock one to see if it's misshapen or bent. Its also possible a tiny piece of debris is in the way preventing it from seating properly to the axle housing causing it to appear that way.
To me making it work is part of the hobby. I don't understand where your coming from though, it's just me.
Charles B I appreciate you checking out my video. I agree about making things work being part of the hobby. It's definitely one of my favorite parts anyway. I also think that not everyone feels that way though. Part of what I wanted to do with this video was to hopefully show that you can make things work and save a few bucks instead of getting the pricier parts sometimes.
@@TJsRC absolutely, tinkering is the hobby lol. I use to be a sponsored racer for a few years, started RC when I was 12 years old and still doing at the age of 45 . Unfortunately sold off most of my old race vehicles and just have a few backyard bashers. The wife has her's and my son as well. It's actually a hobby that can help with multiple thing in life as long as you have an attention span longer than 5 seconds lol
@@charlesb7831 I am a definite believer in the hobby being a big part of your life if you let it. It is my escape from reality when I'm overwhelmed and I find the tinkering to be relaxing, Sometimes I take them apart and put them back together just to take my mind off things. It has been a real life saver in this regard. I also enjoy that more of my family can enjoy this hobby together with me vs some of my previous hobbies that no one other than me was interested in.
Skateboard tape on that board will work wonders my friend!
I actually ended up going with that kind of grip tape. It is working very good.
@@TJsRC the skateboard tape is cheap and can be bought in large flat rolls from skateboard shops and when it wears out , easy to replace. We even use it on our shifter controls on our mountain bikes, trim to fit! Works great in rain and bad weather.
Do you have a speaker making those exhaust sounds? Good idea!
I have a sound kit in that truck to make the life like sounds.
Sandpaper or so non slip step stickers it's like sandpaper but it is a sticker should be good
Yeah i ended up going with something like that.
sandpaper and shoe goo or gorilla glue the sandpaper down. great video TJ.
Bucks RC World Sandpaper would definitely be a good one. I just went with what I had on hand and completely didn't plan ahead😁 very well. Lol
@@TJsRC its all good trial and error for sure. we get to learn as we try new things.
Bucks RC World Absolutely my friend. I have some much fun with this hobby. It just makes me happy playing with these tiny trucks. Ha I sound like a little kid. I always said I don't care about growing old but I will not grow up, ok maybe a little but not all the way for sure. 😂🤣
@@TJsRC yeah i feel ya too, the rc part i think or should i say hope to be doing forever lol.
Thanks for this helpful tips. Btw, how many mm are those brass hex adapters sir?
Japox 33 They are +5mm very minimal because otherwise the tires get to far away from the portal gearbox's and they catch on everything. I keep going back and forth between them and the stock hex's trying to see if there's really any benefit as so far all I have noticed is there's minimal performance benefits and it's mostly just do I want the look of the tires sticking out more or not.
@@TJsRC i have new rims and i cant get thru the hex coz my cheap brass is on d way. So i need a brass hex adpater so i can connect it. Can i use 10mm brass hex adapters? I have a trx4 bronco also.
Japox 33 if you go wider than +5 you will have to get a different kind. With the +5mm I'm already almost out of threads for the wheel nut. Try searching Google with the phrase "TRX4 wheel spacer hubs" there were some wider options there when I looked just now. I would start with the smallest increase that allows them to work. I hope that's helpful.
@@TJsRC can you give me a link of your +5mm sir? Just to be sure 😊😁😊👍
Japox 33 Here is the ones I have, they're from Amazon. If the link doesn't work just search "Treal TRX4 5mm brass wheel widener"
www.amazon.com/dp/B076YWRY7H/ref=cm_sw_r_cp_api_i_JYv1DbRM90NXG
Hi do you have a link to the set you bought ?
I purchased them off eBay over 2yrs ago so that listing link is gone. There are quite a few more cheap brass options for the TRX4 now than there was then. Just search “TRX4 Brass portal” on Amazon or eBay and you should get a lot to pick from. If you go cheap with the portal boxes just watch the tolerances around the gears during assembly. As you saw in the video I had to do some clearancing so the gears would spin smoothly. But after that they’ve held up perfectly since.
If the C hubs don't have an L or R how can you which is which?
With the axle housing as level front to back as possible you will want the top of the C-hub to lean back slightly. So if you put one on and it's leaning towards the front, try it on the other side.
@@TJsRC Dude. Thank you!
@@EricsRC Your welcome and best of luck to you getting it back together. Have fun.
Track width the same with the new brass?
Lane Mullins Yeah, it has to be, the stock hex drive pin holes worked just fine. I did go back and remove my +5mm wideners and go to the stock hex's since Im using the 1.9s right now. If I put the big 2.2s back on I'll probably put the wider hex adapters on also. 👍
Great video. I'm thinking of getting the injora portal covers only for my trx4. They look like what you've installed here. I think i have the same beadlock wheels as you but in orange. Will the portal covers fit inside those beadlocks with the beadlock screws? I'm using the standard offset 12mm hex's. Yours looks extended? Would the covers fit with standard trx4 hex's in there visually from what I've seen i think things look pretty close!
Cheers
I think it should work, maybe. I had the plus 5mm hex on my TRX4 already but I think I’ve tried the wheels in the video with the stock hex’s and I want to say they worked but I can’t be sure. I’ve had a number of different wheel and tire combos on it since and I know I had to do a little sanding on the outside of the portal box for clearance on one set but I can’t remember which one. The good news is that if you need the wider hex adapter they’re not that expensive but do not get wider than +5mm or you won’t have enough threads sticking out for the wheel nut. Searching “ +5mm hex brass TRX4 “ on Amazon reveals a number of options. There’s even a +3mm which might be enough to make the room if you need it while not changing the appearance as much as the +5mm does. I’m sorry I couldn’t be more exact. It’s been a while since I made this video and I’ve changed things up a lot on it. Let me know how it works out for you my friend.
@@TJsRC ok thanks. I've ordered a set of portal covers but they're slightly smaller looking not the full round profile like your video. I think they'll work without extending the axles. I want to keep the width as is or it'll start looking a bit silly and less scale! Thanks for the reply!!
Are all the Brass parts the same brand?
I assumed so as I got them all from the same seller on eBay.
@@TJsRC OK. I have ordered some cheap brass parts from AliExpress, they are supposed to be same brand/seller (Injora). After watching this I'm at least mentally prepared for issues with making them fit. 😅
Time will tell when I get them.
What bumper are you running on that bronco?
Sergio D Its the stock bumper off an Axial Honcho. 👍
I thought so but wanted to double check. Looks sweet on the bronco.
Skate board grip-tape?
Lacos 179 Yes that is actually similar to the stuff I ended up using. I went with ladder step grip tape. It came in a roll like duct tape and works great. I just haven't gotten back around to filming any footage of the ramp since. 👍👍
Salut. Buna treaba! Dar rotile din fata sunt inversate, stinga cu dreapta!
Sometimes I do stuff like that just to see if people will notice. Thanks for watching the video my friend.
