Traxxas TRX4 2021 Bronco vs. Axial SCX10 iii Gladiator - 2021 best trail crawler shootout

The TRX-4 Bronco vs SCX10.3 Gladiator are tested, compared on a tough rc rock crawler course to see what's the best scale trail crawler - Traxxas TRX4 2021 Bronco - snp.link/7ab8fc49
Axial SCX10.3 Gladiator - snp.link/0515eef5

[@james...1]

The locking diffs and changing gears are my favourite thing about my TRX4. It adds a whole other element to crawling, and I just don't find crawlers without them as fun.

[@Bikes_N_Adventure]

I only disengage my diffs on pavement to the trails, never really a need to do it on the trail.. now the two speed is nice however!

[@ConditionZero76]

@@Bikes_N_Adventure agree, to me locking diffs are useless in a crawler, dig definitely comes to use tho & 2 speeds ok I can take it or leave it, generally when crawling in real life your going about 1-3 mph

[@wildchicenmuts3198]

I totally agree it makes it so much more fun

[@FarmerFpv]

@@ConditionZero76 2 speed is not useless in a scaler crawler. There are plenty of times when wheel speed got me out of situations that other crawlers could not get through. Locking diffs certainly help in any situation on the Trx4 when you are on descending switchbacks which causes others to roll over rather than oversteer. Hardly useless when you're creative.

[@2nd_boiledtea867]

Sadly it costs like 200 bucks more for me

[@badvermin]

I decided I wanted a crawler this spring, so I spend a few months watching videos and reading about both cars. They are both capable crawlers with decent scale bodies to choose from. They both work great out of the box, are high quality, and have a ton of aftermarket parts. You can't go wrong with either. I chose the TRX-4, it wins with the better controller and features which makes it more FUN, which is my goal when I'm out playing with my car. Being able to lock and unlock the diffs is fun, I'm constantly turning them off an off depending on the terrain. It's fun to watch it struggle, then hit the button and it gets over the rocks with ease. I'm also walking to my park, so the entire time I'm on the street I want a fast car I can bash, spin, and jump, which the second speed gives me. On top of those features, it has cruise control, which is perfect for walking trails. I could not be happier with my purchase.

[@RCReviewChannel]

That's what it's all about. Research, decide, mod, have fun.

I drive with a friend who had to upgrade so much on his Redcat now he's into it $700 and has the same time on as my TRX4. I'm glad for my decision as it was the right one.

[@markcole6475]

I have a few trx4 trucks at different stages of mods and a couple scx10.3 rigs…some mods to one of my 10.3 early bronco. They all perform well but each have their best areas of performance! I think the TRX4 is my overall winner for the locking diffs and 2 speed. Although one of my scx10.3 rigs has a 2 spd and dig which does very well, but the trx4 still out shines it in many ways!

[@robinsonreptiles]

Great comparison as always. I have the gladiator, & I'm very pleased with it, but the bronco has been hard to ignore with it's spectacular looks & amazing performance. 👍

Great video. I have the Traxxas Bronco and have the SCX10 III "old" Bronco on the way. Im going to try and perform all these tests too! Appreciate the channel and all the well-articulated info!

[@RCReviewChannel]

Right on!

[@edsadventures3575]

It’s so hard to judge. I know when I find a good line on rocks, sometimes I can do it first time and sometimes it take several times. They both look very capable. I’m picking trx4. And the reason why is because I have both a trx4 sport and an scx10 ii. The trx 4 is built better. Better quality parts. But I love them both equally!! Haha Thanks for the awesome vids as always!!

[@RCReviewChannel]

That's my take as well. They are very close in performance. So preference on body style and brand can be pursued without much risk. Traxxas has a way better body mount for sure and options with 2-speed and locking diffs.

[@Albertotron]

Agreed. I also have a TRX4 sport and a UMG10 and the plastics are so much better on the Traxxas. Both were a kit so I was able to see how they are put together and how they feel. First thing I noticed was how much beefier the axles and gears are on the TRX4. I also noticed that the drivetrain felt a little bit smoother on the TRX4. I don't have the 10.3 so maybe Axial addressed some of the issues. I love both trucks but if I could only have one, I'd pick the TRX4.

[@edsadventures3575]

@@Albertotron then you know exactly what I’m talking about. The only thing I thought was neat about axial scx10 ii was the curved gears in the axles. Not sure if that’s for torque twist or strength but I thought that was nice to see. I will always be an axial fan. I had the scx10 dodge power wagon. Never broke other than the plastic links would bend.

[@edsadventures3575]

But I sure do love the trx4 as well.

[@icup7802]

Its for the noise, scx10 have strait teeth, scx10.2 have helicoidal teeth for noise reduction, same as real cars exept for reverse wich is why it is louder thant other foward gears. The inconvenient is more stress on the bearing due to sideway force. Pros and cons... noise for longevity...

[@LEORedSun]

They are both good crawlers but I will go for the TRX4 for the remote locking front and rear differentials functions. I feel it's just more fun able to change the differentials on different situations. BTW, the SCX10 III whining running gear noise just drive me crazy. Don't have that problem with the TRX4 especially on two wheels drive.

[@LonerTrails]

Man I was bummed out at 1st when I seen traxxas released a 2021 Bronco body. But the more I see it, the more I slick debate getting one. They look freakin’ sweet! Especially the dark red one.

[@Nico-bv6hi]

Hey :) great comparison! I really want to buy a crawler soon but i can't decide which one. I kinda likr the Bronco but i'd love to see some interiors. It looks so empty without eventho the bodys sick. Are there any interiors or which one could you recommend the most to maybe put in some work and modify them also with a new engine etc.? have a great day

Hi! Nice Test! TRAXXAS TRX4-BRONCO: these body-mount (snapper), folding mirrors, Diff - Locks, Two Speed (good for a Trail - Crawler), AXIAL SCX 10 III GLADIATOR: good Performance /articulation, grip... I like both... If you not an expert, buy them RTR and have fun!!! I(Gladiator "Owner") think, for trailing they are good, you can't be wrong... no matter witch one you buy. If you will tune them, there is enough to find for the Gladiator (it is longer on the market). TRX4-BRONCO: I don't know what fits from the TRX4-DEFENDER...

[@AllanGarro]

I have both. I activated the second gear on the Axial (extra microservo, 4+ channel controller). Besides making it more expensive, the second gear is barely faster than the first. Traxxas gives you the right controller with the second gear and you really notice the speed difference. But no light system on the Bronco and bad servo as is Traxxas tradition. That was another $180 to put lights and decent servo. In the end, both are a lot of fun and great quality. Just consider if you want to spend that extra money on any. If I had to choose any based on no extra budget to spend, I will go with the Axial, because it has lights, decent servo and dig function which is cool.

[@RCReviewChannel]

Yeah, the 2-speed of the SCX10.3 is really an embarrassment to their fine car. That's perhaps why they don't ship it with it and don't have a capable radio to even do the upgrade. It's a lot of hassle and barely faster than first gear.1.5x. Gladiator performs well though and this packaging hits the spot.

[@AllanGarro]

@@themountain59 I have 7 crawlers. They all have great things as well as not so good or bad things. My favorite brand is Traxxas. However, not everyone can buy more than one and not everyone can afford adding extras. My goal is to help those who have a shorter budget, as a way to consider which one is best for they needs.

That was a great Apples to Apples comparison. I seem to go with Axial because of its history. Traxxas has a LOT of components that “could” fail. Really there is no looser.

[@RCReviewChannel]

[@kenbrandmier3678]

I just bought a TRX4. What size battery are you running (and where?) and what shock-top-mount position do you have the rear shocks placed in?

[@GCrasherPR]

My only question is when you complained about the turning of the axial after the side hilling and V notch. You said the turning radius on the TRX4 was better. But you forgot to engage the dig. If the dig was used as needed that part of the performance would not have been an issue right?

[@RCReviewChannel]

That is a good point. We thought about that too while editing the video and seeing that 3 point turn on the notch descent. There are a few situations where DIG would have been handy and that is one of them in this video. Maybe we'll do a separate video on DIG and when it works and doesn't in our course. Problem is half the time, it causes failures since the vehicle will slide down. Same with lock/unlock diffs to some degree.

it's not superior, but the kit version" 12.3" can't compete with the 13.9 gladiator not even close, the Gladiator will nearly climb a vertical wall, it will far out climb the Bronco straight up or sidehilling otherwise there pretty close... in stock rtr form the Gladiator will out climb my Thousand dollar custom LCG build as far as vertical climb & sidehill without tumbling.. 👍🏼 Good luck

[@RCReviewChannel]

That is not a bad idea. Will try that. The reason is the two bodies felt on equal footing without the rear tire on the trx4 hanging off the back. The bed rack of the Gladiator put it close to the SUV body of the TRX4. Also the TRX4 has a heavy internal clipless body mount structure. Wanted to test the two chassis really and not have something that really mess up abilities
