[@kennystroner7431]

Good call on the bumper removal! I did the same thing and climbing improved so much more! I replaced my tires and replaced them with aluminum rims and tires. Does so much better. I didn't want to add too much weight to it. I was able to increase my climbing angle by almost 8° increase. I can climb better straight up, but coming down its more likely to roll when I push that higher degree. Still does the best when you just remove the top cover and can pull just over a 60° angle! Can't beat that with a stick! Have you thought about putting on a lighter shell on either of your TRX4's? Good Video Sir!

[@billjonesnation]

Thanks for the review. Still debating on the classic or the new sport model!

[@thereasonableamericans411]

[@RCReviewChannel]

Simplifying the complex is our goal.

[@Nickeeefy]

My trx4 is so good right now for crawling. stripped down it completly, all the plastic stuff and mini servos for diffs is gone. I centered the rest receiver and esc(hobbywing 1080) on the ram close to the motor, took out the receiver from the plastic box and covered it with a ballon and zipes. Got a few small 800 mah batterys and put in front between Servo(srt 35kg ) and plastic front thing. Bumpers is also gone ofc. Got heavy rims 140 grams with a modified brass Pieces around THE steering knuckle + extra weights around that 150 grams each Side. Also some weights around the differential with zip tied and glue. Body is the team c samurai only 80 grams. This is a very cheep way to get a Good crawler it beats some really expensive rigs om competion.

[@allthethings7226]

Nice video. Nice to see you suggesting the cheaper mods that the other guys don't.

[@ArielsSmartyPants]

Nice informative video, but I'm a scale guy, I put small wheels and tires and bolt on a lot of crap all over them :)

[@ztwntyn8]

I relate fully. Steering servo will need replaced for sure at some point from failure. I’ve gotten by on the torque they make with driving style. My defender no longer has bumpers lol they def are in the way and I’ve got plastic beadlocks with lead weights. Still stock motor and has been submerged several times and ran many hours same as my son’s tactical. We are happy with performance in torque crawling and speed in hi gear especially with 3s but I’m fine with 2s unlike a slash or Losi Baja Rey etc

[@michaelg6415]

I got my TRX to crawl real slow so I'm interested more in better throttle modulation of motor speed (I could use 1/2 the sensitivity of the stock throttle response) and a slower steering would go a long way in the realism dept too. I saw your vid on the FOC motor/controller which I will probably get, but what steering servo would you recommend for slower response ?

[@tomandrews5392]

Have you had a chance to see the JX CLS-HV7346mg servo you will definitely need a BEC?

[@tomlucasrccrawlers9108]

I despise the beeps. I put the Bluetooth module in it. Plus , mine never hit the ground with stock electronic's. Black Label 650oz Protek 370 brushless WP servos, Mamba X esc and 1800kv Revolver went in it. Never even ran it with the stock body either....I had a Pro-line Chevy body painted-up even before I bought the TRX4. I'm obviously one of the few that does this but I've been in the hobby for 30 years....so I have plans for every rc before I buy it. Anyway....you're spot-on with your review. Great video.

[@RCReviewChannel]

Thank you! We are not alone!

[@SternLX]

All these problems are why when I decided to buy a TRX-4 I bought the Assembly Kit so I could pick my own electronics and not have a bunch of stuff from a pre-built laying around I was never going to use.

[@raffymagaling2516]

how do you fix wheel wobble on crawler

I have a problem with my crawler. It moves so slow. I took it to a shop that put it on a computer, than asked me if i want it to go as fast backwards as it does foward. I said sure. Now it goes as fast forward as it did backwards. I am 4 hours away from the shop that did that. Do you know when he could have done and what i can do to fix it? I am really hoping i don't have to go back.

[@DirtyRC101]

You can also use a lower turn motor which will speed it up the higher the turn motor the more torque you will have

[@jediradekcrif9568]

What do you think of the Brazin LCG chassis?

[@RCReviewChannel]

Do not now and have not heard anybody recommend it yet. We think it's much easier/effective to play with brass weights for weight distribution

[@jakeedinger4547]

I bought a brand new trx-4 Chey Blazer in the orange . When i removed it from the box, i noticed the paint had cracked and was chipping. I have talk to a few people that deal in Rc and contacted Traxxs

[@safeplayz9338]

Even though the reciever is 4 channel, all the diffs, transmission, etc. is still functional through the reciever

[@jameskratzer4538]

Point Blank: ADD BRASS Portals!!! More than anything else, they will improve low speed traction, control, and handling. They're NOT cheap, but for the price vs. return break, they're worth their weight in gold. I bought a plow attachment for my Defender, and with the brass in front, I surrender the rear diff to gain the plow lift servo, and I can clear up to 1.5" of snow from my front walk in less than 30 minutes without leaving my (covered) porch!

[@RCReviewChannel]

great advice. it is key for offsetting the weight of that great body

[@ziggyzbeak]

please give me a link for brass portals thank you

I got mine at the local branch of Remote Control Hobbies here in town. They do have an online store, I just don't know the exact link, or I'd gladly post it for you. One warning: like anything else, if it's free, it's worth what you pay for it!

I’ve been running 3s from the start for about a year now. Finally burned out my esc. I’m not sure if it burned out cuz of the 3s or just inevitability. You’ll likely burn it out at some point. When you do, get the hobbywing 1080 esc. It’s cheaper and better.

I have seen a video that shows heavy portal axles actually make no difference at all and in fact, as the lean angle grows it forces the tires to role on it's side and loose grip.

[@hopnglo680]

I put brass portal covers on the front axle only on my TRX4 High Trail. It made a significant difference in roll-overs and crawl ability. However, i would not do the back wheels or add a lot more weight than just the portal covers.

[@joedipietro2559]

Great tips thankyou. But the edits to your clip made it look like you forgot what you were talking about or changed your mind on what you were talking about. But yes it's some great advice and correct. I was just about to buy a Traxxas F150 Foord TRX 4 high lift but now I'm thinking about saving my money. Here in Australia that F150 high lift costs $1100.00 AU. And then it's going to need all these upgrades? Yeh well now I don't think I want it anymore.great looking body and a capable performer ,the mechanics and chassis are excellent but let down by being fitted with parts straight from the factory which need to be upgraded. A steering servo is pretty easy and so is upgrading a motor and ESC but when my local shop does not have the stock this leaves me unable to use my truck. Maybe I'm approaching this from the wrong perspective then and I need to make this truck a project and a work in progress to be built and modified and customised but not left stock standard ? It's probably going to owe me around $2000.00 AU by time I get it right and that will still be with the plastic portals not brass.traxxas has got a bad reputation for warranty also in australia.maybe due to Traxxas Australia distribution supplier?

[@ronbradshaw7433]

can the shifting servos handle 7.4 volts?

[@RCReviewChannel]

No. To do 7.4 volts, one has to wire an external BEC to just power the steering servo. The stock BEC can power the rest like normal.

[@RCReviewChannel]

The shifting servos definitely cannot handle 7.4 volts.

[@JKZ103]

If you want to just crawl get the trx4 sport. I got one and now I never use my defender. I am about to sell it. Good video bro. One more thing some may say it's the "best" but my scx10 ll kit is trying to say otherwise....

[@nicholasbennett2358]

you could go full metal running gear that will lower the weight

[@billymanilli]

I don't get why Traxxas decided to make these with ultra-realistic "stockish" looking bodies and rims (like the Blazer and Bronco for example), and then put portal style axles and everything under it. I know they obviously have better ground clearance, but it's just too unrealistic, imho...

[@ChipsA17]

Honestly. I have no problems with my trx4 g500. J dont need it to turn that fast when im crawling or speeding. It will flip or im taking my time crawling. Body does get in the way sometimes.

Not recommended

Steering also sucks because the panhard bar flexes

Poor body prefer when it’s heavy and cooler

You don't actually need an external BEC. I've been running Hitec HS-7955TG high-torque servos on the internal BECs built into my ESCs for 6 years and they all work fine. You won't find a servo that can handle 10 amps of current (or a steering system that can handle the force generated by a 10-amp servo) anyway. I'm sure Castle's 10-amp external BECs can handle the power they're rated for, but they're still just as unnecessary as 1000-watt subwoofer amplifiers or oxygen-free copper cable in your car stereo. ALL COPPER CABLE IS OXYGEN-FREE, OTHERWISE IT WOULD BE RUSTY! But I digress...

How many amps do your ESC's produce. We find that many of the RTR ESCs produce 1 amp only.

@@RCReviewChannel: Depending on my power needs and motor setup, I use the SkyRC Toro SC120 (5A @ 6V), the HobbyWing 10BL60 (2A @ 6V), the HobbyWing WP880 Dual (4A @ 6V), or the HobbyWing WP1080 (3A @ 6V). None of these ESCs are particularly fancy, so if most ESCs only provide 1A of current then I'm going to suggest people stop buying their electronics on HobbyKing, DealExtreme, Banggood, and other factory outlet sites for no-name electronics.

I think that's the key that you're using high powered ESC's with good BEC output. The RTR ones are pretty sad at 1 amp.

[@deusexaethera]

@@RCReviewChannel: I've always seen external BECs recommended _in addition to_ an upgraded ESC, so that's the scenario I was commenting on. If you have an upgraded ESC from any reputable brand, you almost certainly don't need an external BEC, and _nobody_ needs a 10 amp external BEC.
