Here are some Mini Mod tips to make your Mini faster:

(1) Use strapping tape to hold your batteries - no side braces

You can adjust your weight bias left to right to offset your batteries from center.

(2) Remove the two chassis braces from the chassis for more rear bite

(3) Add a small rubber band to the steering ball to steering ball to keep the arms swept back to remove play and wheel wobble

(4) Remove all transsmision ball bearing covers and grease - dry and lightly oil with a synthetic lubrucant.

(5) Add a light spray of silicon to the plastic transmission gears and then add a dry graphite powder

There's more later...
