XRAY - Model racing cars

Jlong,

1. Running the shock on the lower holes will give you more down travel which will help on rougher tracks with good size jumps like most of us run on here in the states.

2. It sounds like you are running on a very high bite track and for that you are going to have to land the car differently coming off the jumps. If the car is landing flat or more twards the rear tires and you get on the gas immediatly then you are going to pull wheelies all day. It may help to go to a lower center diff oil but not that much. When landing you need to get the front of the car to land first so that when you apply gas it will pull the rear of the car to the ground and if you do land on the rear of the car then you need to let the car settle before jumping on the throtle.

3. As far as traction rolling and things to try:

1. Add more camber (Ex. if at -2 then go to -4)
2. Try lowering your roll center.
3. Go to a thinner sway bar.

Hope this helps,

Thanks Jason...I think its the little things like this that you notice "good" drivers doing to get thier cars going.

I noticed at a race a few weeks back that if you don't hold the throttle while on jump faces, the trucks attitude would come off the jump more nose down so I could get back into it on the double double section for the next set. Plus it seemed easier to hit the backside of the jumps that way.

Just some food for thought. I used to hold some throttle while heading up to the lip of the jump and it was much harder to negotiate the nose down effect and still backside the landing nice and smooth.

I figured this out by listening to guys like Kelby Roberts and some of the other local sponsored drivers going through the rythm section doubles and they were all off power on the jump faces and all the trucks were nose down almost right away off the jumps, and they could just lean on the throttle when they hit the backside and then let go again before the next jump face.

It allowed for less mistakes too once I got used to the rythm of doing that.

You got it.
