Qualifying & Racing Rules

 

*The race course and event format will be discussed in the driver’s meeting. Each participant is required to be present
during the driver’s meeting. Any and all questions can be addressed during this time regarding the events and scoring.

 

  1. Each participant will qualify their truck(s) on each lane of the race track. The best time will be used to seat the truck
    into the racing bracket. Any truck that does not receive a qualifying time will be given a DNF (Did Not Finish) and
    be placed into the bracket accordingly. Quickest qualifying time will get lane choice in eliminations.

  2. Once a racer has “staged” his/her truck at the starting line, the other racer has one minute to stage his/her truck.

  3. A five minute grace period will be allotted only if the racer encounters a problem at the starting line. Each racer will be
    allowed to receive only 1, five minute grace period per race.

  4. If the truck moves across the staging plane before the green light is illuminated, then the red light will illuminate,
    indicating a false start. This is an automatic DQ, and the other racer will advance automatically to the next round.

  5. Trucks are required to come into contact with obstacles (i.e. crush car ramps or ramps) with any combination of two
    tires.Track Marshaling is not allowed.If your vehicle flips over and can’t be saved by its own power your run is done.

  6. The truck may not hit or come into contact with any part of the timing system or its barricades during the run. If this
    happens, it will result in a DQ.

  7. When trucks are competing and both completes an illegal run, A re-run will take place.If only one truck makes an illegal run
    the opposing truck will be granted the win only by a legal pass.

  8. In the event that all four tires go into the opposing lane, the truck will be disqualified. If only two tires cross, and you
    are able to recover, you are safe.If a driver runs into the opposing lane and makes contact with the opposing truck it will result in a DQ.

  9. In the event that a racer with multiple entries in the same class should have to race themselves, each truck will run one
    at a time on the track in different lanes. The truck that records the fastest lap time will advance to the next round.

  10. In the event that a winning competitor cannot make it back for the FINAL round of racing, the competitor he/she beat
    will be inserted back into the bracket.

  11. No electronic steering assistance will be permitted. Examples: Spektrum Active Vehicle Control, Traxxas Stability

Ultra mod was created to give builders a place to put a scale driveshaft truck. Normally a scale truck with a cage and the extra added weight would not be able to compete in pro mod or sport mod due to its top heavy design. The vision for this class is to have builders design a truck that is scale in appearance and speed.
