Default XXX-S Issue

Hey everyone, I'm obviously new here. I used the search button some for my problem but I didn't get anything useful.....

I got my first car for Christmas, a Team Losi XXX-S RTR. I know a good amount about how suspensions work, and I set up the front wheels to toe out about 2 degrees for good initial turn-in. However I just ran it to make sure nothing would fall apart with the wheels off the ground, and when I use the accelerator and turn the steering to lock on either side, I hear a fairly loud grinding sound from the wheel that would be inside the turn and the suspension vibrates. The CVD is at a pretty sharp angle at the spindle and carrier, but it's no more than 45 degrees. I'd like to keep the car set up with toe-out, but how do I get it to work without the grinding sound? I'm also running -1 degree of camber on the front.

Thanks for any help

I would check to see if the diffs are functioning smoothly, then look to see if there's some flashing or clearance issues between the axles and the hub / carrier assembles. On my XXX-S G+ I had to dremel a little material and hollow out part of the carreir so the CVDS didn't hit the carrier at full steering throw....

Other than that, not quite sure what's up there....

Turn the dual rate down on your radio. The wheels are turning too much and it's putting the cvd at too extreme of an angle and thats the chatter you are seeing/hearing.

i had the same pronlem with the uni's

the pin in the uni's are to long and is hitting the upright as it spins
to fix it, i pushed the pin more to one side then got a dremel and sanded down the pin to leave just the right amount so the uni's still works and in doing this it fixed the problem.

I had the same exact problem with the xxx-s, and it seemed to be two problems actually for me...The first problem was that the CVDs were grinding like stated above (still have not fixed this even with dual rate very low) the second problem was that the tires rim was actually grinding away at the bottom of the shock towers on each side of the car... I helped to somewhat fix this problem by going to a smaller tire width, I believe it was 26mm...Hope this helps...

Won't the turning radius get a lot bigger if I turn the dual rate down? I don't know how big is big, but it's already about 5 feet.

Also, what upgrades should I look into the most? Graphite body parts, shocks, slicks, or something else?

What do you plan on doing? Racing or just driving around the street?

ive bought heaps of spares but havent used any yet, also with the carbon parts they have a more attendency to snap as there is not flex, but i would get a one-way and ball links for the steering up right as mine keep popping off once i hit somthing.

My first car was a XXX-S RTR and this is exactly the problem it had at the front end.

i would invest in a ally motor clamp as i had problems with the plastic one i found that as the motor was getting hot the motor mounting plate was getting hot and expanding the plastic causing the motor to shift and strip the spur gear
