I was sent a copy of the rules for the Scout class tonight. Looks pretty much like BASX rules (but no oil allowed):

The wheels can be trued to get to the 2.4 gram weight but they are not to be cut down intentionally under the weight limit and use foreign material to bring it back to weight.
Wheels may be removed and weighed after the race to verify they are legal.
LUBRICATION
Only dry powdered graphite is allowed, no type of liquid lubricants.
Once the car has passed inspection, it may NOT be retrieved for lubrication.
REPAIRS
If a car malfunctions during a race, the race will NOT be restarted unless the car interferes with another vehicle or fails to pass the finish line and register a time in its lane.
If the car crosses the finish line in its lane, the results will stand and race officials will determine if the participant is allowed to make a repair before the vehicle's next race. After the car has passed inspection, any approved repairs must be made under a race official's supervision and within a five-minute time limit. Upon completion of the repair, car weight will be checked again for compliance.
The following Modifications are not allowed
A.Starting or finish line devices B. Electronic or lighting devices C. Glass or extremely fragile parts. D. Paint that is wet, smudges or extremely sticky. E. Bearings and/or Bushings. F. Sharp objects, sandpaper or abrasives on the bottom of car (We do not want any damage to the rubber stopping pads). G.
