The easiest thing to do if you are happy with the way the car handles otherwise is to adjust how you approach the jumps. Just as the front wheels hit the base of the jump, let off the throttle. Right after that give full throttle and this will take weight off the front of the car causing that end to lift. The first thing I usually do though in cases where even changing the approach doesn't help is to increase the rear ride height slightly. This keeps the rear of the chassis from bottoming out when you hit the face of the jump.

Jamracing- XXXNT setups don't transfer well to the electric truck. Francis' current XXXT setup (which I think is his Nat's setup) should work well for you. You can find it on the Losi site, or I could give you what I've been running lately on my truck.

Mr. Losi - The only problem with the ceramic bearings is that I believe that they are illegal at ROAR and IFMAR events. Although I doubt anybody will know to tech them.


TC3 - As far as setup goes for the XX4, try the most recent Todd Hodge setup. That is very close to what I have been running for over a year and works quite well. You might also try the setup Francis ran at the nats. I haven't tried that one but am told it works very well. On the Hodge setup, you might try changing the rear dampening from the 54 - 40 to 56 - 25 or 27.5. I have never liked the 54 - 40 rear's. It makes the back of the car to sluggish, kind of the wet rag syndrome.

Well I'm selling my xx4 to someone who wants it. Everything was fine till all the sudden a bunch of problems came up. Its too much money now... who all has had really bad belt problems even with the new green ones? They were skipping like mad. Oh and it was a used xx4 I bought so that might explain the problems I had.

Default belt problems

007yoshi,
I experiance the same problem too. When I got my xx-4 and used it for 2 years, one after another the belt broke. after I replace them they are working fine, belt slipping does not happen to me.
I replace front and side blue and rear red.

however in my rally weapon, just for 2 months on weekly used, my side belt green snap too, but now ok. I don't really know which is durable the blue or the green, I think belts for the xx-4 and rally weapon has to be repalce every year or every other year.

The green belts are the most durable ones and are meant to be used in the XX4!

007yoshi: The slipping is most likely being caused by worn pulleys, if you have already replaced the belts with new ones!
When the teeth on the pulleys get worn down and smoothed over they will slip easily!

Yoshi and others - It is important with the XX4 that anytime you break a belt, replace all the pulleys that the belt ran on. If the belt skips enough that it breaks, the pulleys are toast also. It may seem expensive but it will make everything last longer overall. If you are repeatedly breaking front belts, check to make sure the chassis has not cracked where the front threaded inserts go thru. This allows the front suspension assembly to twist and stretch the front belt to the point of breaking.

Mr. Losi - right now I am the sole distributor. I have had offers from Schumacher and a few other places to distribute but I am just doing this myself and have a hard time keeping up with the work as it is.
