Default XXX-4 Question

I just picked up a XXX-4 and dont know much about dirt. I hear that is very fragile. I want to make it as sturdy as possible. I hear there are aluminum front spindles and carriers. Who sells them? Thanks.

The xxx-4 isn't *that* fragile, but it depends what you crash into of course.

You can double up the front shock tower but then you need longer screws. I ran mine with 1 front shock tower though because I was concerned that a double tower would eventually break the chassis in a hard crash.

I was good enough not to crash really hard but get those front carriers. That's like the #1 broken part I had because the regular plastic ones take a lot of stress from big jump landings. At the time I owned my xxx-4 that place was out of stock the entire time.

Losi aluminum inner pivots are good to have also (both front and rear).

This is an old article but it has some more info:

The G+ style graphite towers are plenty strong and you only risk breaking a chassis if you double them up. It is alot more expensive replacing a chassis than a shock tower. The only thing that is really needed on this car is a aluminum front pivot. The rest of the car is quite durable. The carriers do break from time to time but not that often. I would keep a set on hand if you do not want to go the aluminum carrier route. Also, the aluminum CVDs are nice but wear out quickly. Replace the aluminum bones with the optional steel units for better durability.

the fiberglass shock towers are a necessity on the xxx4. the plastic ones break very easily but the fiberglass can take some abuse before cracking. and when they do crack, they still stay together so you can probably finish a race.

the front arms have been updated at some point. look for an "X" shape molded in at the middle of the arm on the top and bottom. those are quite a bit stronger than the original type arms.

these parts from x-factory look like they should also strengthen the car quite a bit. i plan on picking some up soon... http://www.xfactoryrc.com/news_09_27_06.htm


it's not really a fragile car, i raced against a bunch of xx4's today and only broke a castor block due to a high speed run-in with a pipe. it doesn't handle rough parts as well as a xx4, like washboards, but the straightaway speed and corner exit acceleration more than makes up for it.

Those longer Kingpins should help to strengthen the carrier block too. I use the same carrier blocks on my X-5 as the XXX-4 and rarely break one.

I haven't actually raced my XXX4 yet (just got it a few weeks ago from a guy in MN). I've been practicing with it quite a bit, and i broke the chassis in the same place the other dude said he broke his. Also, i've broken 2 ride side steering knuckles. But they are like any other car, when you hit the pipes, they like to break. I broke steering knuckles twice on my T4 FT as well too so i'd say so far they XXX4 is pretty durable. Keep in mind too that 99.9% of the time people are running some freakin insane mod motor in them, and anytime you do that you're not only going faster, but because of the car's accelleration, they car is carrying much more momentem (gotta love those engineering and physics courses )then it would with a stock motor, and therefore hit things harder and stand a bigger chance of breaking the more vulnerable part.

The 4wd electric buggies are designed for mod motors because this class is a mod class by default. I doubt you will find a pinion recommendation for a stock motor in your XXX-4 manual.
