:: Tuning Tips
Tips for Beginners:
Before making any changes to the standard setup, make sure you can get around the track without crashing. Changes to your car
will not be beneficial if you can’t stay on the track. Your goal is consistent laps.
Once you can get around the track consistently, start tuning your car. Make only ONE adjustment at a time, testing it before making
another change. If the result of your adjustment is a faster lap, mark the change on the included setup sheet (make additional
copies of the sheet before writing on it). If your adjustment results in a slower lap, revert back to the previous setup and try another
change.
When you are satisfied with your car, fill in the setup sheet thoroughly and file it away. Use this as a guide for future track days or
conditions.
Ride Height:
The standard starting point for ride height is 5.0mm (keep in mind that your local track may have minimum ride height
requirements). You can slightly raise the rear relative to the front to give the car more steering. Raise the car slightly for tracks
with large bumps.
Battery Placement:
For most cases, run the battery in the standard forward position. Typically this will be the most stable and easiest to drive. Try
moving the battery back if you encounter a low traction surface by switching LiPo braces front to back.
Ackermann & Steering Rate:
Ackermann refers to the relative angle difference between the front wheels as they are
turned to steer the car. The outside wheel will turn less than the inside wheel in most
conditions. Settings with more Ackermann will have a bigger difference in wheel angle,
causing the outside wheel to turn less. Likewise, settings with less Ackermann will cause
the outside wheel to turn more.
Increasing the Ackermann will smooth out the steering and is used most often on high
traction surfaces such as carpet. This is a result of the reduced outside wheel angle.
Settings with reduced Ackermann will help to increase corner entry steering, and are
typically used when running a spool in the front.
The chart to the right lists the different Ackermann options.
Wheelbase:
Lengthening the front will reduce steering, shortening the front will increase steering. Shortening the rear will
increase rear grip, lengthening the rear will decrease rear traction.

Rear Toe-In:
The TC6.2 allows rear toe adjustments in two positions: inner hinge pin, and outer hinge pin at the rear hub. In general, decreasing
rear toe-in will decrease rear traction and increase corner speed.
Rear toe-in can be adjusted by 0.5° increments at the inner hinge pin with
supplied arm mount inserts (see chart to right). Standard toe-in angle for
inner hinge pin when using same insert front and rear is 3°.
Standard insert used is 1 dot.
Use rear hub inserts to change toe at the outer hinge pin by 0.5° increments.
Note the number on hub insert should be on outside of hinge pin for proper installation.
