Poor Steering...

[Brushless Moose]

My slash just doesn't steer nearly as tight as some of the others at my local track. I have checked everything, and it still has a huge turning circle, especially under throttle. all of the endpoints are maxed out... Are there any mods that will SIGNIFICANTLY decrease the turning radius?

You can use the toe right?

[Acer]

What you are experiencing is "push" or understeer. This means that the rear tires have more traction than the front.

You can decrease this by:

Shocks
Use heavier oil in hot weather and lighter oil in warm weather. If
your rc car is understeering, try lighter oil at the front.

Shock position
Move shocks out one hole on the arms.

Camber
In general, more negative camber means increased grip. Go to -2 to -3 degrees on the front.

Toe-in
If the car is pushing (understeering), removing some front toe-in will remedy this. Try wheels straight or slightly toed out.

your king pins are bent i have a stampede it does the same thing when they bend

[Billstmaxx]

try another servo?

[Cainam]

Check for binding in the suspension, and check the shocks to make sure they haven't leaked the oil out.

[Brushless Moose]

nothing is binding, and the shocks are 40wt all around.

Do you have full travel as compared to other Slashes on your servo?

Are you running toe-in or toe-out on your front wheels?

Do you have negative camber on your front wheels?

[Brushless Moose]

no, no, and no.

[GForce]

Is it less one way or both ways?

[Acer]

No, as in "No I don't have full travel of my servo as compared to other Slashes."

No as in "No, I don't run toe-in or toe-out."

No as in "No I don't have any negative camber dialed in."

I am trying to help you here Moose but you have to give me something in the way of information. Any one of those things could explain why your truck is pushing. If you don't want any assistance I'll back out of your thread.

[Brushless Moose]

I don't think I am getting as much travel as the others. I have a little neg. toe in the rear. none in the front. I have a little neg. camber in the rear, and a little less in the front.

[dereckg]

sounds like you need some neg camber like someone else allready said go -2 or 3 start with 2 should be better

[Acer]

The rears are set up with a fixed toe-in angle, you can't adjust it.

If you look at page 19 of your manual it will explain all the adjustments you can make. Pay particular attention to the toe and camber portions as this will affect your on track performance.

If your servo is not turning the full throw I would call Traxxas Customer Service.

Adjusting your CASTER and TOE will help..

[Carbonrevo33]

Yeah, and maybe add some weights to add some additional help?

I wasn't aware you could adjust the caster of the Slash. Do you have any tips for this? Are you using original Traxxas parts to do it?

Caster is defined as:
Caster angle is the angular displacement from the vertical axis of the suspension of a steered wheel in a car, measured in the longitudinal direction. It is the angle between the pivot line (in a car - an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical. Car racers sometimes adjust caster angle to optimize their car's handling characteristics in particular driving situations.

The pivot points of the steering are angled such that a line drawn through them intersects the road surface slightly ahead of the contact point of the wheel. The purpose of this is to provide a degree of self-centering for the steering - the wheel casters around so as to trail behind the axis of steering. This makes a car easier to drive and improves its directional stability (reducing its tendency to wander). Excessive caster angle will make the steering heavier and less responsive, although, in racing, large caster angles are used to improve camber gain in cornering.
