Ok so I am maybe 10 tanks in and my spur gear stripped. So I took mine to the house while my friend continued to drive his. Well I come back a few min later and watch him drive his since he hasnt had much of a chance to drive his since he got it.....and he stripped his gear. Whats up with that? he was maybe 7-9 tanks in and this happened. We both had issues with the clutch nut backing out after every tank so we both replaced them. Then trying to get the clutch adjusted was either it would pull the front wheels off the ground wot or it wouldnt move, even adjusting 1/16 at a time. I see that you should go to a metal spur gear because it puts stress on the transmission but wth. With the carb being messed up from the factory, the steering servos were way off, and my friends tire shredding before his last tank of break in I am wondering about the quality of these trucks.

i havent had any problems with mine ...and i have at least 2 gallons burnt in it ...still on the factory spur gear
Well, it is a hobby and these things are just churned out of factories as quickly/cheaply as possible. Which means adjustments may be necessary out of the box to make sure everything is tight and aligned properly.
The design of the revo is pretty good as long as you respect physics a bit.
If your chewing through spurs and tearing up tires, it's more than likely your driving habits may be a bit out of bounds, along with a few adjustments to the vehicle. Of course, could be a complete fluke as well.
Chewing up spurs is usually due to the engine moving due to vibration or direct impact. In some cases, having improper gear mesh out of the box.
Blowing out tires is usually due to running WOT with no load on the truck. So running WOT in the air to complete that double back flip may blow a tire. Or sitting and whipping a doughnut for 30 seconds at WOT on the dirt can cause it. Or jumping and running on concrete with off road tires will also blow a tire since it chews up the inside of the rubber. Eventually it just gets weak and the centrifugal force tears it apart. I had one blow apart on me, but it was because I hit a landscaping spike and ripped it, then centrifugal force finished it off.
Carb being messed up (bad tune or loose carb cinch bolt), steering being out of whack, gear mesh being not right, all are typically RTR things that a new user can run into.

I did my friends breakin so there was nothing out of the ordinary from the traxxas break in then his tire just shredded. And as far as the spur gears I am not sure what the deal is with those. We both were running dirt/grass/asphalt and 3 teeth gone before 10th tank. Like I said the clutch nut was a issue on both our trucks but we replaced them.

Locktite on the nuts would've solved that issue. Correct mesh would have saved the spur. I've been running the same spur for close to two gallons. Tire sounds like a fluke. These problems you are describing are all avoidable with preventive maintenance. Making sure your rig is ready to go, even a new rig, is 1/2 of the hobby. Make sure you apply locktite to any metal to metal screws. Blue, removable locktite. This is especially important when setting the mesh, which involves loosening the engine mount. The engine screws must have locktite on them, or they will vibrate loose, your engine will move, and your spur will be gobbled up.

Gone - bye bye.
Which is very true with Traxxas, being probably the biggest manufacturer in the hobby, they make more of these things in half the time other companies do. That being said they do have their problems, because they are tryig to make as many as possible, not always getting the quality most people expect from them. Locktite would have fixed a few of the issues, but as for the tires, you must re-glue them because Traxxas as mentioned before tries to get everything done as quickly as possible and doesn't always glue the tires on very well. If your friend re-glued their tires before running, then that would have been prevented. Also make sure the clutch bell on your engine is tight against the spur gear, but loose enough to allow a piece of paper to go between them without jamming up the gears. Dont forget to do your routine checks after every run making sure everything is tight, and maintain every part that needs to be maintained. Doing so will extend the life of your trucks.

1 up on the locktite! Mine got loose after god knows how long of running and now its like new again. Funny thing is tho that my friends let loose like 5 minuets after mine and his rig is like 2 yrs older? I Love my revo!
Sorry, I missed that sentence in your first post. That sucks that you got a weak locknut out of the box. I bought both my revo's used, so one of the first things I did was locktite the snot out of everything to avoid issues.

Well got her back up and running....then I was hauling @ss in a dirt/grass lot and hit a hole or something that sent the truck cartwheeling about 4-5 times. Then I go to take off and notice the back driver side of the truck is sitting way low....I yanked the shock piston out of the adjuster lol. I got it put back together so we will see how long it holds. Is there and upgrades that are not plastic for the shock pieces? Man I love me some nitros At least now I will know what to check out of the box or buying used.

Actually, plastic is easier to deal with because it's cheap. Busting shock shafts gets expensive, so I don't run alloy ends anymore. I bought a full set of revo anno'd shocks with tini shafts off ebay for what I would have paid at my LHS for just 4 TiNi shafts.
Alloy rockers and alloy shock mounts maybe, but personally, I'd stick with plastic for the rest.
I tweaked two of my ball ends on my rear shocks last weekend. One way more than the other. Couldn't figure out why it was sitting kind of crooked... A detailed search found me a ball end that was bent almost to a 90 degree angle. If that was alloy, probably would have snapped my shock shaft.
Just get a bag of pushrod ends and shock ends to keep on hand. When you notice slop, change them out and order another bag.

Thanks for the help all.

When you're done learning how to drive you can get a new revo and sell me yours for 50 bucks.

Sounds like a deal. $50 for the Revo and $450 shipping.
But this deal can only happen in a couple years.
