I've removed rear roll cage and roof top lights. And that has improved my centre of gravity greatly. Excellent video!

[@BroncoSteven69]

I did the axe 3300. Reefs 444. Portal weights all around. Hyrax predator. Weighted wheels in the front. (220 grams). +3mm wheel spacers. It can do 71 degrees or more climbing. 48 degree side hills. It is amazing.

[@RCReviewChannel]

We forgot the wheel hex spacers that give it 8mm of offset per wheel. Great for lateral stability to offset high CG body. Here: snp.link/d79f6785

I enjoy your videos

[@MCsCreations]

Awesome mods, dude! Thanks for all the tips!!! 😃 The magnets for the lights is a fantastic idea!

[@RCReviewChannel]

Crazy huh? So genius since it's like an auto switch too. The key is to use Rare Earth magnets for ultimate power. And that thus needs to be bolted on or bonded with a very powerful glue so it doesn't come off.

[@discusdog]

Back in the day I used metal washers to do the light switch. This was before magnets were strong enough to hold the shell on

[@paulclancy2404]

@@discusdog o yea thTs good idea too as its easy to solder to washers

[@MCsCreations]

@@discusdog Great idea as well! 😃

[@MCsCreations]

@@paulclancy2404 Actually, you don't need to solder in the magnets. There are magnets with holes for screws, you know? For example, I'm thinking about getting some to make a 18650 charger. And you hold the wire with a nut. 😊

[@GForceSS]

Awesome video review. Love this rig

[@RCReviewChannel]

Crazy huh? What are your favorite mods.

[@GForceSS]

The Traxxas 400 oz servo, metal steering arm and BEC you recommended are stellar performers. I added a CCHAND grille guard. And a Warn 18 lb double motor winch.

[@rodcognito002]

Every one thinks I'm crazy when I say it takes a grand to play. Worth it.

[@RCReviewChannel]

We had our doubts but this one has a massive sweet spot for fun.

[@KTMcaptain]

It does and it doesn't. The only two issue it has out of the $600 box is horrific drag brake and weak servo. Gearing it down further would help the drag brake, maybe the 9 tooth pinion would give enough extra leverage for the drag brake to work effectively. And there are cheap servos for $25... add a $22 castle 10a bec plus the $6 pinion and you have a $650 rig that is going to be even better at crawling. Maybe even throw in a HH crawl master sport for $20. Mine, I put in a mamba x and puller pro 2700kv combo along with the traxxas 330 servo. I didn't go with the 400 servo because I saw RC Review's video comparing the two outputs and they were within 15ish ounces of each other at both voltages, but the 330 drew like 1.5 less amps. So i'm already at that grand mark without touching batteries, but I can recognize that its only slightly faster and, well a bit, quicker than the brushed version. So is the performance that drastic without the brushless system, not really... except for the drag brake which is amazing with a proper motor setup.

[@snuffwolf3715]

Awesome Channel !! It would be cool if you could create a cart with the items you linked with the AmainHobbies.

[@paulclancy2404]

Itz os cool and look good in the house offroad decorating 😎🚗

[@667Gurba]

I use the same motor combo and servo but I replaced the micro servos to PowerHD TR4 and run 7.4v. The Traxxas 2255 got a lot better.

Have the black body , upgraded to Traxxas 330 servo and Boom Racing aluminum wheel with Injora 1.9 Super Swampers . Wow this truck is unstoppable, the crawl mode in the esc is fantastic 👍🤗

[@RCReviewChannel]

Yes, we bought it as a novelty but it's surprised us every step of the way. It'd done many previoiusly 'undoable' lines. Try the $40 Hobbywing 1080 ESC at some point and you'll be blown away with the modulation and braking control. 14 configurable options too.

Magnet mount is cool

[@mbdroneworksmbdroneworks2108]

Have you tested overdrive in the front axle, with the speed do you think overdrive would be okay with the speed as well as crawling?

[@michaelmunderloh2285]

I’m new to the RC world as an adult, I acquired a TRX6 Snap-on car hauler and the 21T550 is shot. I love the idea you bring up of doing the motor upgrade. I have a lot of questions but the main one is besides the pinion gear (this model says it’s 9-T), will the motor mount plate need to be changed? And anything else down the drive train?

[@KTMcaptain]

7:05 Yes the vehicle is heavier... but... it has 50% more tires to support that weight. Side hilling a 9 lbs rig with 3 wheels supporting the majority of the weight is actually the same load as a 6 lbs vehicle with 2 wheels supporting the majority of the weight. So the sidewall shouldn't flex more. Now, climbing onto objects where the intermediate or rear axle is lifted will shift the majority of the much heavier truck onto only 2 wheels, but that might just provide for a greater footprint and traction.

[@shingod700]

Did you try the trx6 with hyrax, does it make a big difference on steep incline?

[@arshadhai2777]

Is 3650 Brushless Motor 5200KV compatible for Traxxas TRX-6? Please let me know before I purchase for upgrading my TRX-6?

[@knightmpw]

What are the best size crawler tires to fit in without extending the wheel base?

[@kennethsmith2536]

Please let me know what 14t pinion did you use? Traxxas 14t center hole is to small.

[@rex_factory]

So, I'm watching this in 2023, and I am looking for a Hobbywing AXE 550 FOC Waterproof V1.1 Sensored Brushless Combo w/3300kV Motor but it says that the motor is discontinued online. Is there any other websites where i could order it?

[@erikmoore7402]

That brushless motor doesn't mind crawling at super slow speeds? I was thinking about upgrading to a brushless but I didn't wanna lose that super low rpm ability.

[@pcrodriguez03]

I’d like to tell my local shop the exact motor and servo upgrades I want. Can you please tell me what to tell them?

[@tjenkins1126]

This blows me away! Honestly just thought this thing was an expensive novelty. Never really thought of it's actual crawling capabilities. Good info as always 👍🍻

[@RCReviewChannel]

Exactly our reaction.

[@KTMcaptain]

You didn't think an extra driven axle increasing the surface area of the tires contact patch by 50% would benefit? Now I thought it would have trouble with maneuvering, but that's the miracle for me.

[@voorheeslaz70voorhees12]

Nice!! My hun got me the white one and she also got me the tax-4 Bronco for this past Valentine’s Day. Do u think my trx6 Benz still has the same sorry servo and the other components that u mention. Thanks

[@RCReviewChannel]

Same servo yes!!

[@Traulus83]

Just run a BEC and a bypass cable and you can run a HV steering servo, withput afecting the voltage going to the tiny servos

[@rcadventures5940]

Was curious about this because I have the exact 550 foc combo in my trx6, but am I overpowering the micro servos by turning up my HW ESC to output 7.4volts? The micros on my defender have failed with the same set up, so I was wondering if using the HW esc feature to turn up the voltage would do this Thank you!

I just blew up the motor in my Trx6 and actually replaced it with the stock one. New motor coming sooon

[@speedy6135]

The link for the mounts to automatically turn on when body is placed on doesn’t work. Does anyone have the link pls??

[@ricci169]

Do you put drooping the center axle?

[@MisterESP1]

Howdy from SATX! I strongly believe the ProTek LiHV 3s 4100 mah would make your top 5 list! ... in fact, for all TRX’s ... so small and very lightweight but powerful with that extra voltage ... it gives it a very noticeable extra punch ... the stock esc accepts it but only comes in deans connecter so I recommend you remove the connector on the battery (and the stock esc) to avoid the hassle of an adapter ... very recommended though! 👍🏽 ohh and I can charge 4 at a time per channel on the hobbymate duo pro no problem 👍🏽👍🏽

[@eric1138]

The point being it is a good battery to use on the provided front mount space, right?

[@RCReviewChannel]

right on. Great advice. Glad we tried LIHV. Extra pop!!!

[@Moonsauc3]

Flatbed half cab 👍

[@surfside75]

Servo/integy mount, lcg battery tray, long travel ss hc links, club 5 hc steering links,120mm shocks, integy shock towers and braces, brass on all 3axles, widened 12mm brass hex, sliders raised 5mm/sides and rear trimmed. -working on a custom rear shock/lever setup for more wheel travel, as is its so limited with the second axle actually lifting the 3rd😮 a bit. Will experiment with freeing the rear axles much as possible to reduce binding and resistance to input at angles same work on gaining more travel with keys. I know the rear driveshaft is the issue, I will sort this out too. Many problems require many solutions😂❤

[@Kouwe81]

Thanks for all the reviews. I just bought myself a TRX-6 because of your reviews ;-) But i got a question: the servo upgrade: you recommend a Traxxas 400, yet your comment also says a Savor 1210. It seems for the Traxxas 400, that you need a seperate servo-horn ( that's fine ) and a high-voltage upgrade kit ( TRX2262 )? With those added, it costs €130 just for the combination, but the Savox 'only' 80. Is that High-voltage kit really needed? And only for the Traxxas 400, so not for the Savox??

[@Kouwe81]

And again: i watched another review: kzbin.info/www/bejne/kGjdeKF6fJ2Co5Y And my question is answered ;-)

I already have a heavily modded trx4 and I’m looking to get another crawler. I’m stuck between this and the Capra. Which would you choose?

[@jeremyh3445]

I'd say it depends on what you want to do. They're both different from your TRX4. The TRX6 is obviously similar but will be different enough to be fun. If you really like trailing and want to drive a big bad 6X6 then obviously TRX6. If you want to do more slow technical rock crawling then get a Capra. You can still trail with it but that's not its intended design in my opinion.

@@rcadventures5940 i just ordered the HW Axe 550 3300kv with Xerun ESC combo. I guess the bluetooth device is for connectivity to the transmitter, not the ESC itself.

What dual stage foams do I get that fits 2.2 wheel and 1.9 tire?

[@frumpadumpf5173]

Maybe a 1.9 dual stage from Crawler Innovations, and stretch or carefully cut the inner foam to fit 2.2? 1.9 and 2.2 shouldn't be a huge difference in size, so it's probably not too difficult to stretch it on.

[@KTMcaptain]

You'll need different axle links and rear most driveshaft in order to get the thing to clear the rear tires. And moving the rear axle further would give issue to the locker cable, so you can either relocate the servo or spool up that axle.

Laszlo Earle RC you’ll want to buy the lift kit for the trx4... personally, if I went down this road I wouldn’t buy the extra shocks and leave the intermediate axle stuck with the 90 mm stock shocks and place the 110mm long arm shocks on the 4 corners.

[@laszloearlerc7155]

@@KTMcaptain the thing with the long arm lift kit is that it does not improve travel due to limiters it only makes the cg of the truck higher where as if you have shocks on full droop the cg will be the same because it will sit at the same hight or just a tad higher but the axle will be able to droop down more and the lift kit is tediously expensive

[@KTMcaptain]

@@laszloearlerc7155 That's actually a common misconception. Longer travel shocks and springs will allow the body to lean further. That would make side hilling much more difficult. You can remove the limiters from those shocks and run it at a normal ride height. Either way the rear tires don't have enough clearance not to bind on each other without those extended arms.
