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
Although I have not yet finished building this kit, I am quite happy with this purchase. The quality of the kit is evident from the moment you open the box to start the build. The parts feel sturdy and go together well, and the instruction manual is perfectly clear. The only additional information I would add would be to disassemble the dampers and be especially careful to not over-tighten the bottom of the shock bodies. Just applying some green slime o-ring grease and only making the bottom cap hand tight really frees up the shock shaft to move more smoothly. I would certainly recommend this kit, and really hope the trend of building kits will continue to be a popular choice for RC hobbyists. The only reason I did not rate this kit at 5 stars is that, for the price, I personally would have preferred durability option parts, like metal drive shafts for example, rather than the scale accessories that come with the body set.
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
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.
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.
Best price value kit in the market so far... I spent around 1 month comparing the features of the Element Enduro Sendero, Axial SCXII, SCXIII, TRX4 and TRX4 Sport and I decided for this one. The reasons for my decision were based on many factors, but the most important ones for me are: The kit comes with a complete set of pieces to assembly a high quality truck within a pretty decent budget, the kit includes a high quality body, tires, pre-assembled shocks with oil, pre-assembled links, portal axles, bearings, metal gears, and more. The electronic components like an ESC HobbyWing 1080wp, a cheap Holmes Hobby 21T TrailMaster motor and the ecoPower 120t were my selection to build this budget truck. All these components plus the TRX4 Sport kit are the best value if we apply the diminishing return law calculating the benefit or performance provided vs. the cost of the truck, especially if you have other cars in your RC arsenal and you don’t need to buy a battery and transmitter/receiver. The build process was really enjoyable, it was one of the best experiences building a kit with my son (7 y/o). The manual is very detailed, no errors, colorful and well organized. my kit came with a wrong part and it was easy to detect the problem, I requested support from Traxxas and they shipped the right part needed to complete the assembly right away. All parts of the kit fit smoothly, the screws are well identified and classified, and the manual shows the real size of small components where comparisons are a bit difficult with the real parts. After a week running the truck by a 7 years old boy with some experience in RC, I can see the real performance in the trail of this little machine, the weight with the default configuration is well distributed using the battery in the battery tray for trails. Also, the options to control the speed, brake force and drag brake with 1080WP are a great benefit for this truck to adopt different configurations. The articulation, approach angle, center of gravity and realism are very well accomplished out of the box in this product, of course there is room for improvements. By the way, regarding improvements, another decision factor in this purchase was the number of optional parts provided by Traxxas or third party RC builders, specifically for this truck. At this time the best accessory that I have purchased with the kit was the stainless steel screw set (TRA8298), this tiny box includes all chassis screws to replace the ones that comes with the kit, however, I have started a list of additional parts that will help me to adapt this truck to my needs.
My two cents are: If somebody wish to spent quality time with the family, working in a project and having fun, this product is the perfect solution in a very reasonable price. BTW, this truck it's very quiet, it's not a rolling clicker!
Its an excellent kit, the packaging is almost perfect, like any kit, only 1-2 missing screws. I was surprised for the quality of plastics, and how its that everything fits perfect. I put the SnowPanther brushed ESC and 35T 550 motor on this kit and it works great with 19t pinion! It took me 3 hours to built and paint, its extremelly easy to build, and an excellent manual. I really like not to have 30 sizes of screws, it makes easier to build. I compare it with SCX10.3 and I like this much more. Its simple and functional. And theres a lot of hop ups.
Great kit! It took me about 2 hours to build it no hiccups and went together smooth and all parts very high quality, if u want a first kit or just one to add to your collection this is a great choice.
Great kit. It was storming where i live so i listened to the rain and built this awesome truck. Parts bags are organized by steps which is one of the reasons i went with this kit. It was mossing 2 screws total but i had some in my rc spare parts so it did not slow me down. I am happy with my purchase and always trust Traxxas products. Amain shipped fast as usual so thanks for another great experience.
Great product! Very fun to build with an awesome, full color manual! 10/10 would buy again!
Awesome kit. Even easier to assemble than anticipated. In my opinion one of traxxas’ weak points is electronics this way you get to choose your own! Problem solved
The kit arrived in perfect condition on the date offered
I really enjoyed putting this kit together. It has been years since building a kit from scratch and this one went perfectly. The instructions are great. Step by step and even with review photos to make sure your progress matches what it should look like at the end of the sections. All went together well and no issues. My only complaint would be that some hardware bags are not fully used until later in the build. It would have been nice to have those pieces separated into other bags to not make you panic or second guess your self with your progress when you have a dozen screws left over from a section. I would recommend this kit for anyone looking to build a really nice trail truck/rock crawler.
Awesome product! Fun, easy kit to build with great instruction.
Great kit with top notch instructions. Easy to assemble, nice bodies and accessories. Love the truck!
