  • Page 39 BEFORE RUNNING YOUR NEW 8IGHT 2.0 OFF-ROAD RACING BUGGY for the fi rst time, you should run down the following checklist in order and complete the listed tasks. We’re sure you’re anxious to get out and run your new 8IGHT 2.0 now that it’s built, but please note that fi ne-tuning of the initial setup is an essential part of building a high-performance racing buggy such as your new 8IGHT 2.0.

  • Page 40: Setup Guide

    Team Losi Racing development team has put hundreds of hours on the 8IGHT 2.0 to arrive at the setup we put in the instruction manual. If you fi nd that you have lost the “handle” go back to the vehicle (stock) setup, as this setup has proven to be reliable, consistent and easy to drive.
  • Page 41 Differentials: The 8IGHT 2.0 comes equipped with 5000 wt in the front and center diff , and 2000 wt in the rear diff . Thinner front diff erential oil increases off - power steering, but if the oil is too thin the steering will become grabby and inconsistent. Thicker front diff erential oil increases off -power stability and increases on-power steering.
  • Page 42 Outdrives and Traction: When your 8IGHT 2.0 is new it will have a lot of chassis roll and be a little loose on throttle due to lack of friction in the out drives and crossbones. After about 45-60 minutes of running, the 8IGHT 2.0 will gain traction and stability. Once your 8IGHT 2.0 is broken in, replacing the out drives and crossbones with new parts will have more corner speed.
