Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
Well worth the money in terms of RAW POWER, POINT and SHOOT and the LACK of BREAKAGE.

I bought the 8s X-Maxx at a local hobby shop with hopes it would be a relatively maintenance free vehicle. With only a few quirks, I am VERY satisfied with this truck.

On a rainy day in wet parking lot, the truck is a great drift machine, the traction control is helpful if you need it. I have a tree rooted and rutted track in my backyard, this truck handles the occasional crash into a tree, misaligned ramp jumps, tumbles, cartwheels, and flips. Stock gearing on 8s is great for speed (around 40 or so), with tremendous wheelie power and oomph for attacking short run ups on jumps, dirt piles, gravel hills and the like. The size and power of this vehicle have doubled for an has left numerous DEEP ruts on my track.

This vehicle has been as maintenance free as I could ask for considering how much I run it. In 50-80 battery packs (10-15 minutes each pack) I have had to replace two front caster block bearings, a spur gear, two caster block hinge pins, servo gears, and the rubber cushion in the cush drive. The body is starting to see some wear now, the tires are at the halfway mark, the CV joints will need replaced soon, the shocks are just now showing signs they need more fluid, and the pinion and spur gears will need replaced in 10-15 more battery runs. No plastic parts breakage, two hinge pins have disappeared from off square landings. I suspect the plastic flexed enough for them to exit. More to that point, I have a habit of after a run to spray off with the hose and spray down with WD-40. I've heard testimonials this softens the plastic to keep it from breaking. Also MO94 (a PTFE lubricant) does similar.

The quirks or flukes I have had to deal with were early on and non-recurring. The ESC had some false positives in terms of overheating/low voltage shutoff. Sent it back to Traxxas, flashed it and sent it more problems. The firmware upload for the Tx and Rx was a little frustrating. The upload hung up several times, had to restart and re calibrate the ESC to the Tx. Once completed it was fine.

I am by no means abusive with this truck, but considering as hard as I run it, this thing was worth the money to me. The battery charger combo is good for the money as well, just one plug, hold a button down and it does the rest. I gave 5 stars despite some of the out of the box difficulties; these difficulties were counterbalanced by the sheer fun and lack of taking anything apart or rebuilds.

Big AF! I'm so happy to have received my blue X Maxx right away, this thing is the ULTIMATE BASHER. I've had it for a few days and beat it up as hard as I would beat my E Revo Brushless, but to my surprise, everything is still working flawlessly. Now the Brushless Revo is for the street only and the big boy X Maxx is going to be for the trails and skate park.

The Revo on 6s is definitely faster and quicker, but is it really usable?
The X Maxx on 6s feels good, but on 8s it really opens up.

Traxxas says the Brushless Revo was "built for brushless" but that is really the label for this 8s X Maxx, It is incredible.

However, the Revo Brushless is way more fun on the street, but the X Maxx is way more fun off road.

And PS, Traxxas takes care of us, their customers. I had a wheel wobble because of a bad glue spot on the tires, and Traxxas took full responsibility and replaced the bad wheel/tire.

I have had the truck for a month and have beaten the truck up pretty well, and it hasn't had to have any repairs. So the guy below that said its not built well iis full of ishh. THIS TRUCK IS VERY DURABLE and I am very pleased with the build quality.

Really cool, yes it's plastic for a good reason... it's supposed to flex. If it had metal components it would instantly bend, up grade to castle's 2028 motor like I did and you will be doing 55mph on 3s! 70mph on 4s!!
It is tough it's ment for off road, I have not broken mine yet because I beat on it, I'm not nice to it at all, I drive it like I stole it!!
The people complaining about it can't afford it, they need to go back to their tamiya cars and quit crying.
This is the baddest truck ever made!
I own them all and this one is all around the best by far.
Mic drop this kids......

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
I have many Traxxas and Arrma rigs, all are awesome. Usually take out the Slash and Outcast and they always make me smile think 'yeah this is cool...' Tough, fun, and durable. At the skate park people watch.

But then X-MAXX comes out to play and WOO HOOO! Talk about stepping it up!

-BIG, goes through or over anything.
-Lipo's last about 20mins
-Good looks
-Easy backflips
-Sounds Great
-Easy to control at low to mid speed.

-People come and pester you with questions. (Go Away!)
-It's size works against it at high speed. Over 45Mph and it gets a little tricky to stop or turn 'safely'.

VERDICT - Live without regret ... Get one!

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
I love my Green X-Max!

8S is insane fast but does present a challenge when it comes to high speed maneuvers. I would definitely say it is better on off road on dirt or sand vs cement or blacktop. I regularly use 6S or 8S @ 50% limit in training mode and it is still fast.

I did break a lower control arm, and a hub after a high speed accident with a cement barrier, but $20 worth of parts and a week later I was easily back up and going. The design of the X-Max really makes working on it and doing repairs quite easy. I also did have to reinforce the Lexan body undercarriage with fiberglass cloth and shoe glue to keep the body screws from pulling through. (about $15)

Everyone wants to drive it, but they shouldn't! Kids (especially my kids) really are attracted to it and want to drive it "all by themselves" but this is not a kid toy. If your kid smashes into a stationary car with the X-Max it WILL damage both vehicles and YOU are responsible for BOTH repair bills. Please exercise extra care in who you allow to "drive all by themselves" as this small piece of advice will help you immensely in terms of head aches and operation cost.

After 4 months of ownership I have spent ~$45 on parts total and I am loving it!

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
I own this truck and had it for well over a year.I customized everything on it.Now it's heaver than stock.WORD OF ADVICE STAY AWAY FROM THE RPM A-arms STICK WITH THE STOCK A-arms.NO matter what negative other people say about this truck.I LOVE IT.It's one of my favorite RCs and i have many.It's not my fastest RC but its fast enough and has plenty of power.Very fun truck to drive.The motor tends to get a little hot and I have to let it cool some times.But over all I highly recommend this large scale RC monster truck.I would most definitely recommend it over the REDCAT Rampage MT PRO.The X-MAXX is the same size as the REDCAT RAMPAGE MT PRO but is much lighter more reliable and has a much stronger drive train.

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
So good after owning one for a year I had to get another! It definitely became my most favorite RC by far, it's huge, it takes an absolute beating, its stupidly easy to work on, and the absolutely looooow price for replacement parts! Most replacement parts on the thing are less than $10, if not less than $5! I have quite a few other 1/8th & 1/10th scales that cost more than the Xmaxx to repair, which in the long run has really shone through, so I keep reaching for it almost every time I go out for a bash.
Not only is it really tough, but when it does inevitably break, it won't destroy your wallet.

BEAST MODE!!!! The 1st day I got it. I couldn't keep it on all 4s.. I lit the tires up doing wheelies up and down my street.. My neighbors and ppl passing by was in shock of how fast & powerful it is.. Including I. On stock gearing 54/18, I did 53mph on 8s 6000mah 100c Lipos. I swapped the gears out to 46/22 & now my top speed 73mph on STOCK Esc! INSANE!!!

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
I've had mine a year now, so feel I can now review this with extensive experience.

This is the only (serious) RC that I haven't modified. I got mine second-hand from a guy who had run only on 8S and the truck was still in great condition. Since then I've only ever run it on 6S, 20' jumps at a BMX track, this thing has NEVER broken a part (knock on wood). This car is still completely stock!

**FWIW steer clear of the RPM "Traxxas X-Maxx Oversized Rear Axle Carriers" RPM81732 - I've reviewed these separately.**

I can't vouch for this truck's durability on 8S (plenty of people will) but I can guarantee that on 6S this thing is the most durable RC I've ever owned.

As Ferris Bueller so wisely said, "It is so choice. If you have the means, I highly recommend picking one up."

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
Iím sure the traxxas fan-girls will come flocking to down vote this review too, but the truth will be told nevertheless. The X-Maxx just isnít worth the money it costs. Itís big, and thatís about it. The ESC is utter trash and should have traxxas wrapped in a class-action lawsuit at this point with their incredibly high failure rate. Inexcusable for a product at this price. Itís cool to witness at first, but then youíre left wondering why you spent so much on an oversized toy. Do your research if youíre looking to spend this kind of money. The competition offers so much more.

Traxxas X-Maxx 8S 4WD Brushless RTR Monster Truck (Blue)
This car is an absolute disapoitment
Everything is plastic and breaks so easily
And it is impossible to find aluminum parts
After a 2 FOOT jump it landed on one wheel and it stripoed the servo and broke both upper and lower arms
Its so klunky and slow
My 2s sv2 goes faster
Its so awful and i hate it so much
If it was maybe 400 dollars less then maybe it would be worth it
All of the electronics are terrible like i said the servo stripped when i landed a jump and replacments are 90 dollars! And they are awful
Every single gear in it is plastic
If you are looking for a good moster truck get something else this is not the one
Im not a huge fan of traxxas but they make alright cars for beginners but after that they are awful because if you race them then its not even traxxas anymore because you have to get all aluminum parts and brand new electrinics because they are all so low quality
Please do yourself a favor and buy something better

Not worth the money to many plastic part. If u jump anything higher then 5 feet it will break very quickly. Don't take me wrong it a nice truck but not as tough as u think. All x max owner go jump a 4 foot ramp and see if I'm right or wrong. Not worth the money for the price it have way to much plastic part that flex and break
