NOTE: The following Welcome Letter is intended for guidance only, it is not official from MARC. The Meet Race Committee may revise this Letter as necessary for their specific meet.


We are glad you registered to compete in the Hubley Derby. The race will be held after the Welcome Reception on Tuesday, _________, at 9:00 pm, in the ______________________ .

Please check in with the Meet Personnel before noon on Tuesday. Participants may be allowed to test-run their cars individually on Tuesday afternoon. No competition will be allowed during the test-runs.

The following are some helpful suggestions for the entries:

  • Be sure the inside surface of the brake hub is smooth so it will run freely against the brake drums.
  • Sand the outside of the brake drums smooth to remove any casting seams which will allow the wheels to run more freely.
  • Apply dry lubricant, such as graphite, to the axle so the wheels spin freely.
  • Tires have a tendency to fall off the rims on the later models. Try to remedy this problem, before the meet.
  • Assemble the front end with the screws connecting the tie rods facing out. This will make it easy to adjust and lock the front wheels, if you choose to do so.

There will be awards for winners of each age classification. There will also be a Best Overall trophy awarded to the winner of a runoff of the top winners from each class.

Depending upon the number of entries, the Hubley Race Committee has the right to combine classes or change the age groupings to maximize the competition.

Good Luck. The awards will be presented immediately following the race.
