Already had the original TRX-4 Sport RTR crawler; but, wanted to build the kit for the experience. Excellent choice on my part because the build was very enjoyable and I learned a lot about the TRX-4 drivetrain. Traxxas did an excellent job of packaging the unassembled parts in bags and accompanied it with a flawless assembly manual that took me step-by-step through the build. And the supplied clear truck body with all its detailed attachments is so pretty for being a lightweight shell (which I prefer over the hard shell bodies). I could not be happier. Now, back to the AMain website to select a few options...LOL
I put the Hobbywing 1080 brushed ESC and Traxxas 21T 550 motor on this kit for a budget build and couldn’t be happier! If you want more speed, you’ll have to go brushless. For crawling, it’s perfect. Bought an extra kit for for a 12 year old and he put it together with minimal supervision.
I didn’t buy this kit from here. I was going to but when I went to purchase it was out of stock so I found it at Rcsuperstore. This kit is very good quality and very durable! This was my second time building a crawler kit. First one was the Vattera ascender. Took me about 3.5 hours to build. 2 hours faster than it took to build the vaterra. Seems to be much better quality than the Vaterra. Great kit and turned out awesome! Big time traxxas customer and I highly recommend this kit! Oh yea the realistic headlight/taillights look really good! I ordered the headlight light kit that has working turn Signals and brake lights
Unbelievable quality and performance. First crawler kit (came from U4/sct/rock racing)and I am extremely satisfied. If you are familiar with building a Tekno kit you know the instructions are the best in the RC world. The instructions included in this kit are on par. There is an abundant supply of aftermarket parts available to really make it your own. The body/rack/scale accessory parts are much higher quality than I was expecting. Performance is undeniable. I purchased along side several upgrade parts(mainly drivline and some brass) and dropped in a complete Tekin electronics setup(RX4-ROC412HD 3100KV-t-360) with Futaba 3pv. Using the tekin hotwire I turned the speed all the way down and torque all the way up. Bumper mod is a must front and rear off the bat. More aggressive approach angle/look and can still use front and rear plastic parts without modification. Keep weight as low as possible and extend width by 4mm add good foams and tires(although stock are not bad) and it's a mountain goat. Climbs 60*+ angles without hesitation. Highly recommend. Like do it....if your debating at all, like I was, you will not be disappointed. Read the instructions carefully, everything you need to know is there, and you will not have any issues.
This is an exceptional RC kit, with the best instruction manual I have used after building 9 RC kits. I use it as a trail truck with the stock Traxxas tires and it has taken a beating rock crawling and has not broken.
The kit just arrived and everything about it looks great. The manual and the associated parts bags very well marked/labeled . My son and I plan to build this kit and make it our own. If your thinking of a kit to build, give this one some consideration. Well done Traxxas!!!
Great shipping, was super fast......I love amains wish list features.....but as far as the kit its the best way to get to know a trx 4.......you really get to learn so much more with this kit and the packaging is superb the links come assembled and packed nicely every section is labeled like the shocks transmission and chassis.....The quality of the kit is just amazing.....i learned how portals work, how to put together shocks, how transmission works, and how to mount a motor....gave me alot of confidence. This is my first 1/10 scale and first kit/build.....i purchased my first rtr cr12 tioga from amain and the shipping again was great....the tioga i still run but decided to build a gspeed build off of trx axles and thats why i bought this kit im using the shocks and axles and transmission.....also since im not using the body, wheels, bumpers, roofrack, or chassis i would like to let you know that most anything you dont use in the kit has a great resell value either locally or on ebay.....for instance the shocks alone at my local hobby shop are 90 dollars......thebody 50$....the light buckets and roof rackaccessiories another 50$ and so i fo instance will make back atleast 60 dollars on this kit....the only thing that was a downside was because of rc reviews's youtube review of this kit i was under the impression it came with high clearance links but it doesnt.....that would be nice however traxxas's hardware and manual are perfect! Also, i was able to put everything together with the tools the kit came with and the diff grease and shock oil that worked great....the axles are very very strong.....the shocks are nice......very nice and upgradable with mini t spring kit......the overdrive and underdrive gears are only 25 dollars each.......a smaller pinion gear option would be something i would make available with the kit because its easy as well as a little tube of loctite but i suggest putting it together with no loctite first if its your first time building a kit.........I plan to buy atleast one more of these.....the foams arent too bad...the tires are good...again they can resell easy if you have a tirein mindyour set on........I would recomend this kit to anyone......you can sell the axles very used at anytime for 120$ and new they are almost worth 200 to me considering the only better stock portal isthe ten3 andits 100 dollars more for that kit and has worse shocks
Super happy with this kit! Excellent instruction manual, super smooth quiet drivetrain, and everything came together nicely. Great kit!
I'm still in the middle of building the kit, but it's been so much fun building it! I hope traxxas have more kits. Thank you Amain for quickly sending the trx4 sport kit shrink wrapped and nice condition box. I didn't order from traxxas cause two cars I had shipped came in beat up boxes that where opened.
Already assembled it and finally today crawling it.
The Trx4 Sport is an awesome truck. I’ve always preferred kits instead of ready to run .the build is enjoyable to me. This was an easy build.
Its the best you can get.
Going to drop in the HW axe 2100kv system soon!
It has been way too long since I've built a remote control kit. I have built many Tamiya, Yokomo and Mugen Seiki kits. I've owned both electric and gas remote control vehicles.
I do not know much about Traxxas with the exception that many of their products are Ready To Run. I am not a fan of RTR, I rather build the kits (you learn more about your vehicle this way when something does go wrong)
I truly did enjoy putting this trail / crawler truck together. The instructions were easy to follow. A must buy if you are getting into the crawler hobby.
This was a great kit and a lot of fun to assemble. Even as our first crawler, my son and I were able to put this together in a few hours and be up and running. We really liked being able to choose our own electronics vs paying for stock and upgrading anyway. The body is nice and heavy and prepared for assembly/paint. I’d definitely suggest this to anyone thinking about getting in to the hobby or looking for an addition rig for their collection. Just beware of the wide breadth of aftermarket parts available and the spending spree that it can lead to even though you can run it as you built it.
This is my third TRX4, second TRX4 Sport. I really like shopping Amain. Their site, search, image quality, customer service and communication is the best in the RC business IMHO. The TRX4s have so many aftermarket options, the sky is the limit from a configuration perspective. They are easy to work on and over engineered so tumbles don’t stop the fun. The two sports are Christmas presents, so I haven’t officially played with a sport. My daily crawler started out life as a 12.8 Defender TRX4. It’s been heavily modded at this point, but I expect good things from the Sports. Thank you and I can highly recommend Amain for any RC purchase. Merry Christmas and here’s to a better year than the one we are leaving behind.
So far, so good. Still building the truck but the quality so far is outstanding. The only problem I have encountered so far is that one of the bearings for the portal axles was the wrong size. However, a quick call to Amain Hobbies resulted in new bearings being shipped. I haven’t received it yet but have do doubt it is on the way.
Kit came with no problems. It was really easy to assemble as all parts where labeled and Instructions was easy to follow
I LOVE the trx4. I've always loved traxxas products, but this takes the cake! I'm currently running a tble 02s esc, some random old battery, and a tamiya motor in it. If you buy this kit, dont just throw in your old electronics. Get some rock crawler specific stuff, and it will turn out a lot better. I have a hobbywing 1080, reedy radon 16t, and a gens ace 2s lipo on the way. I'm using an old slash servo and a stx3 transmitter/reciever as well.
100 percent love it it is my 5th o ne to buld. Love amain hobby.
My first RC kit ever. I put this together with my 6 year old and was a fun activity for us.
Good clear instructions and no assembly issues... almost like Legos. The kiddo did most of the work with supervision.
