Chassis prep:
Shown here is the chassis top and
chassis bottom. Note that the chassis
bottom has countersunk holes. To
prep this chassis you will need to file
the battery slots to keep from cutting
the insulation labels on the batteries.
This will also allow the battery pack to
sit lower in the chassis, lowering the
center of gravity.

When filing the slots, file from the top
side of the chassis with the file at a 45°
angle. Have an assembled 4-cell battery
pack handy to check depth as the
chassis is filed. Removing too much
material will allow the battery pack to sit
too low and could rub on the ground in
high speed corners.
After filing, the slots should look something like
the illustration to the right. If you filed the slots
too low and the battery sits lower than the
bottom of the chassis, they can be built back up
slowly using multiple layers of thick
cyanoacrylate (CA) glue.
