Your videos are helping me a lot. I'm new to this hobby and all this info is new to me. I need to learn a lot to keep my TRX4 in good quality performance. Thank you

My real '94 Bronco was a blast to offroad, only had 33's, 4" lift, 4.56 gears, and posis front and rear. I like the realism of this truck, it doesn't have to be the ultimate crawler. Planning on getting back into R/C soon.

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

I bought it because I wanted the unlocking diffs wanted two speed trans.
I got a basher for going fast I got the trx4 for trailing crawling and going slow . SCALE YESS
Everything you said is spot on for some people and I really like our channel, Cheers

I don't have any crawlers but am highly interested. You explained a lot of things better than anyone else I've watched.
Thank you!👍

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.

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.

"You bought a crawler bro" I died laughing.

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 :)

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!

Best part of this channel - "... AND HOW TO SOLVE THEM" - great videos here!

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