SHOULD YOU WEIGHT YOUR TRX-4?? | Yeah Racing Metal Axle & Brass Upgrade Sets

It's been a year since I got the Traxxas TRX-4 and most of the upgrades I've done have been aesthetic. I really wanted to do something that would make the rig more capable on the trails. RC Mart sent me some Yeah Racing hop-up parts to try out, including the Metal Axle Housing set and the brass upgrade set, which totals 700 g. In this video, I install them and do a before and after video of the TRX-4 out to my crawler course to see if we see any changes in performance due to the added weight.
Have you added weight to your crawler? What do you think?
Thank you to RC Mart.com for supplying product for this video. Views are my own.

I need some serious upgrades on my TRX-4 Sport!

[@tntsmj]

Hey RC Girl nice job. For your issue on descents it looks like your ESC is still set to trail mode which is only 50% drag brake. This is how it is set when new. If you change it to crawl mode the drag brakes will be set at 100% braking. In crawl mode it will stop on downhills if you let off the throttle. 100% drag brake is 100% braking. It also lets you go directly from forward to reverse without having to double tap the throttle control. Doing this makes a huge difference in crawling performance.

[@davidpapastefanou4579]

I like how you show that you are learning and don't know everything like you've been doing it since they were invented. It can be frustrating and I'm glad that's not all edited out

[@BennyTygohome]

In real life rock crawlers there are "suck down winches" and also "limiting straps". Have RC crawlers ever tried those concepts? Suck Down Winch: a small ATV style winch mounts to chassis frame rail or crossmember above front axle and beneath or near motor. The winch rope attaches to center of axle housing. When activated on steep incline obsticles, it sucks down and compresses the front end suspension to prevent suspension unloading on incline when nose is feeling light. Front end "limiting straps" are similar concept but do not compress suspensions, rather just prevents too much front suspension unloading on steep incline. Would be cool to see on RC crawler, even if just there for appearance of realism.

[@RyanRKJ]

I really like the side by side comparisons of before and after the upgrades. Split screen on the same obstacles is awesome. This video was incredibly helpful. Thanks.

RC Girl - thank you for your informative, laid back style. Other channels are a little too much on the "show" that the creators give, and tend to lose focus on RC. Excellent work with this, I know it's an old vid, and I've seen some of your others. Keep up the outstanding work!

[@theirishaxe9405]

I'm finally getting my ten year old little girl interested in RC she likes you because now she sees other girls like RC also. Please do an update on how this brass holds up. Thanks. 😁

[@RCGirl]

Awesome!!! Will do

[@kevincody8391]

Like you i was struck that way also . . . this Gal is a trail blazer! I've watched a handful of of previous videos that always displayed knowledge and sincerity, this topic is a bit more complex and she tackled it w the same results. A terrific role model for girls who are drawn to STEM stuff, talking about it doesn't move it forward, moving it forward does. Hey! we're not eye candy pieces of fluff, we're the real deal. Kind of mirrors rock crawling = progress will be an inch at a time and add up, and good for You, her and everybody that your daughter's choices aren't limited. PS it sometimes strikes me w some of the accessories sold for crawlers and military RCs = grown men playing w dolls. All 3 of you have Fun, fix things and learn along w keep making progress in many ways.

That is awesome!! Appreciate you sharing RC girl. I have the Broncos two of them, I done the brass weights on one of them does make a difference happy trailing

Excellent video. You've given a complete newbie a few things to consider. Thank you for taking the time to create a vid, I know editing can take quite a bit of time. So thanks again.

[@edwinnegron7761]

Just found your video and just started R/Cing, got me a starter dune buggy and having a blast with it. Now I see this TRX and wow. The additional great looking parts are awesome and the side by side was as well. Out of my league for now. thanks for the video

This is a awesome video!!👍👍😎. Those upgrades really do make your rig look even more sick👍 Full watch, and 👍.

Your course looks awesome, super jelly! It seemed to really help the climbing, but yeah, that stair decent was rough. Again, sweet course you have there!

Good grief that is amazing stuff, absolutely stunning upgrades.

Just wanted to say thank you for posting your videos, my 6yo daughter loves watching you and now she wants to build a backyard course like yours!

[@josefturk1897]

Thank you for that great Video and the useful comparison, looking forward for the shocks. Thank god it is raining, more videos for us. :-)

[@stuartroberts9993]

Added similar weight to mine & also bought from RCMart when I visited them in Hong Kong last year; you wouldn't believe how hard it is to find the store! I also bought awesome & rather heavy beadlocks from them which stopped me getting diffs etc. as it would be way too heavy. Looking forward to th shocks upgrade video :)

Wow, what a difference on the rope bridge climb!! Great vid!

@@RCGirl your very welcome, you have a great channel and I've been following for the past couple or so months now even though i havent commented much and see you like different genres of RC like myself. I am yet to fly fixed wing though, have one on the way to review soon , that's gonna be fun trying not to crash Lol :D Keep up the great work and all the best for 2019!!

[@DrBleck35]

Dear RC Girl, I am not a physicist by trade, but I do have a Ph.D. from somewhere in something else. Anyway, Colin Chapman (the racecar driver who founded Lotus) once said something to the effect of "If you add power to a car, you make it faster on the straights. If you reduce weight, you make if faster everywhere." I think that the same principle applies to climb rate and maximum safe descent rate. At some point, I would like to modify a short-wheelbase TRX4 into super low CG Mars crawler. That plus a trailer so I could tow it using my Defender (which is still awesome after three years.

[@scottdaubenspeck2291]

One of your videos for trx4 popped up on my feed so i watched it. NEVER thought id see a woman into RC as much if not more than myself. Thats awesome. Keep up the awesome content

[@islerenner]

This video was incredibly helpful, thank you so much.

[@mmflytie1]

R/C Girl, Way to go...I should have guessed your comment list goes on forever!!!. Great job. , and very thorough video. I am actually getting ready to order a Traxxas 4 Sport truck( after selling my Cross Demon....bad transmission engineering) but I really like the weight and beefiness of metal components. You have solved my problem with this video. Thank you. Cool looks, good performance from an already proven performer chassis. I love your enthusiasm and willingness to tackle the unknown in an otherwise mostly male hobby. Keep it up....we need more of you.

Very nice upgrades and very nicely filmed.

Wow a lady who loves RC. 😱 Adding weight will help the truck planted in my opinion. Definitely subscribing 😀

[@ROCKRATADVENTURETEAM]

Thanks for a true review with video. Great stuff! Keep it up.

[@ViceVersaMusik1]

You can actually see how much of a difference the extra weight (Brass and Aluminum) does for the truck! You can tell just through the video there’s alot more traction... Especially up front!💯 Awesome Video and thanks for sharing‼️💯💯‼️ I’m hoping when my 8 month year old daughter gets older I can get her into this amazing awesome of a hobby💯💯 Cheers

Yeah I want to adjust the drag brake and hopefully that will help with descents. And might end up taking some of the weight off the front... We'll see

[@marvinrlyman8565]

You're awesome, thanks, the only thing I missed was the cost of everything, I don't have one yet, very tempting, yet personally I like the new tactical unit, it's a tiny bit cheaper, & these days saving what I can helps, most my Axial builds have at least an alloy front axle & alloy wheels to keep the weight low but thanks I go look them up as far as $ cost
