After they change to the new show shock tower which most people have, I have only broken 1. I have upgraded the shocks, I use to have the trinity blue bulk head which lasted up until last year. This is my 3rd chassis. Overall in the 10 years that I have had the car, I would say the belts are the hardest to deal with due to the time it takes to change it. I will say this much, the car jumps wonderfully. I like it much better than my XXX-4. The XXX-4 has the same upgraded outdrives. I think the XXX-4 is faster on the straights though.

Guys,

I'm talking about the outer front hinge pins, not the bulkhead brace (which is modded atm).
I can't see any room to simply drill through the arm/hub carrier and inserting a pin without fouling the universal joint......

Yes arms are different. They are a tad shorter than the XX4 arms but overall you only loose about a 1/4 inch to width of the car. The inside arm has to be shaved just alittle to fit on the XX4 bulkhead. You don't need to do this for the hinge pin mod, but I did cuz the XXX4 arms are way beefier than the stock XX4.

You can also see where I drilled a small hole in the arm, I put a grub screw in to hold the outter hinge pin so you don't need e-clips. You can see it better on the right side of the pic.

Im completely stoked about getting back into the sport again.

So now its all about getting my stuff up to date. I need to send my bc112c charger in for a major software upgrade, and been buying battery packs.

Just a thought, its been so long, the best battery i had in my box was a matched 1700mAh NiCad. They still work too, but not race worthy. Now its back to finding out setup that works!

Hope to see you guys around!
Nice results haha. Like I was saying I bought mine just to go to some big'ish' race in OK, where I qualified 3 spots in front of a factory J Concepts/Associated driver, and ended up 2 sec behind a factory losi guy in both of our fastest runs in the triple A's!!!

This car is awesome!

On a short track i ran a 16t/84.....im not sure what the WE spur is....but per the manual, gear it 2-3 teeth lower than recommended equivalent motor. a 6.5 is about a 13 turn, so i would try a 17 for a tight track and 18 for a longer open track and adjust form there based on how it runs. (this is an 84 spur)

Your manual should tell you what to run a 13t mod at and try 2-3 teeth lower.

Lucky I went through and matched all my shocks today, I found a flaw with XXX4 arms on the XX4. Turns out the left side will not except the XX4 CVD. It hits the Diff screw head not allowing it to travel as far down as the right side. That wouldn't be good cuz it could jam the front diff when landing or break a belt. So now I will have to find some cvd's that are a tad shorter for that setup to work.

Default Losi xxx-4 /xx-4 cars

Hi guys. I spoke to an individual at Team Losi about anything new coming out in place of the XXX-4. He stated there wasn't anything new coming out and no plans for anything at least this year. Just to strike up a conversation, do you guys feel the 4wd market has fallen due to the truggies/ 1/8 scale buggies?? I notice last year, many people with 4wd 10th scalers were getting into 1/8 scale. This seemed to be because of the Lipo and Novak Esc explosions that I was hearing about from many of my friends that own the Novak Product. Many people were frying their ESC I think because they were not meant to handle such a high current imput.

Also, what would you guys like to see as hopups for the XX-4 and the XXX-4??

Is there a upgrade from the graphite front A-arms to something different that is stronger. I've done the hinge pin upgrade. I'm breaking them in other places. Delron or aluminum? anybody make?
thanks

You can go with the plastic front arms. I'm not too sure about the Delrin arms, I guess it wouldn't hurt to try them.

A modification that won't cost anything.........don't hit anything.

What would be a good pinion gear to run with my 5.5? I have a few extra pinions from years ago and while re-installing my motor and ESC the other night I went ahead and put a 22 tooth on it for now. As far as the spur gear I think its the stock one.

Well I'm running the 6.5 brushless in my XX4. I have an 18 pinion on it.
You could probably run the same or even a 17 pinion.
