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 excavator...it 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 back...no 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......)

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)
