Default TC4 Steering adjustments and alignment

Hi All,

I have been playing around with my new TC4. That thing is crazy fun.

But, Iím having steering issues. (First, remember that Iím a noob to this whole game.) Here are my questions, what is the best way to or the rule of thumb when adjusting the steering links from the steering rack to the wheels (Hub Carriers)? The Manual said 1.7 inch or 43.5 mm long. But, when I installed them both wheels looked off. (That is when I pinch the steering rack arm and the drive train to center. Is that a good way to find center?) So I adjust them by eye. What is a better way? Look at the photos below. When trying to drive straight, the car is slightly turning to the right.

It is not a trim problem. This is way, when the rack arm is right below the main drive shaft (center), I can spin out going both left and right (360ís). If I fix the trim so the car drives straight (off Center). Then the car does not spin out going right anymore. But going left, it still can.

I also had to modified the servo horn and ball stub connection with epoxy (ball stub was getting lose), and sanded down the steering drag link from hitting the servo.

One last thing, is there an upgrade to those steering linkages?

Like always thank you for your time and help.

I think you may want to try this one in the TC4 forum.

About the steering linkage between the servo and the steering rack, I replaced the one-piece plastic link to a turnbuckle. I also noticed that the plastic one-piece linkage was a tad too long so I shortened it.

Hope that helps.

Use the steering sub-trim to straighten your wheels.

1. With the one piece linkage it is a no brainer as there is no adjustment. Set your servo with the one piece linkage so that your rack is straight.

2. Hook up your steering links starting with the original settings and then adjusting them equally side to side so that your wheels are straight.

It can't be any simpler than that.

When you have that straightened out you can adjust your throw.

Ya, use the sub-trim to make the servo straight. Then if the wheels still look off, then its the toe in. Even with the servo turned a little. Both wheels should be turn a little the same way. The toe-in will have both wheels straight. That might help.
