Inside of body not to be painted
Cars questioned for training mode settings will not run.
A body must remain connected by at least two OEM mounts. If a body is totally removed from the chassis
or being held by only one, the car is disqualified. If a body is attached by only two mounts, judges have the
discretion to remove the car (the added weight dragging around can cause excess heat, and a fire hazard).
----- REPAIR ---------
Bodies can be patched in up to four spots, with a patches measuring no larger than four-square inches
(1x3, 2x2), doubled and attached to the body in four spots.
The body cannot be patched until metal is ripping.
Patches can be manipulated to match body lines.
------- EVENT AND PROCESS GUIDELINES --------
The intention is to put on the best show. One and Dones / heats may not be known until day-of.
Consolations will likely be run at events with heats.
Drivers are subject to inspection, and may not run if tech is failed and they do not make fixes. Cars MAY be
equipped with flags following inspection, or marked and impounded
Heats will have a rescue cutoff of a set time frame, features of a shorter duration.
Once an event on track has elapsed a certain time frame - heats ~3 -5 minutes, the feature ~5-10 - the
rescue rule will be waived and the remaining entries subject to one-and-done perils. The difference being
that, if a driver is to be freed, flipped back over, or free themselves before the 30-second hit clock expires,
they are free to remain in the derby.
Cars will be released from a stuck position only during the allotted unlimited rescue time. It is to their
descretion, and a driver may attempt to wave an official off if needed. No driver is ever REQUIRED to use a
Cars should be put back in the ring with a door against the wall.
It is immediately a fair-access car, and can be struck once moved. Opposing drivers should be congizant of
the officials, and try to avoid driving in the region where the car being saved is located, so as to avoid a
Competition note: Give the rescued car a chance to pull away and move from the rescue.
If you are in danger of being put out of the ring, call for the rescue.
If freed on their own or with help from another driver, it does not count. After rescues are off, you have 30
-seconds to free yourself or be freed by another. Once the clock expries, you are out.
Holding will be defined as using a bumper to pin another car in place.
It is not tolerated in heads-up events.
In team events, a standing 10-count will be put on cars interpreted as holding. This could result in the loss
of a rescue.
Drivers coming to the end of a standing 10 count must back up at a car-length. The car being held may
drive back into the car backing up, and the holding clock will restart as necessary against the offending car.
Blocking is determined as preventing access to a car by using the your car doors.
Blocking is allowed in heads up and team events, with the intent of keeping other drivers from getting to a
Roll overs will not draw an automatic stoppage.
Efforts will be made by officials to administer rescues without stopping the heat, especially if the cars are
near the wall.
Eliminated cars will not be taken from the track. Efforts will be made to unhook the battery for the driver,
and the car will remain. This adds a driver's element, making competitors navigate the course, and adds
another element of strategy in pinning another driver in.
There are only a few instances where a car is automatically out. The first is the body connection clause. A
fire or hazardous situation will result in an immediate elimination and the car may be removed for safety.
Finally, if a car goes over the wall and out of the park, it is disqualified. A car must have one tire still on the
arena wall to use a rescue and stay in the derby. Drivers can call for a rescue in the act of being pushed
out, but must have a wheel inside before calling for the help. These are usually bang-bang and will require
attention of the judges.
Drivers announcing they are out will be scored out at that point. Any cars with time remaining on their
active shot clocks will be scored ahead. Be a strategist: DON'T BREAK OFF YOUR STICK.
If you are calling for a rescue, you cannot be counted out until the rescue is given. Due to traffic, officials
may not get to your car immediately. If you call for help, and were in danger of being counted out, the clock
will stop on you until the car is put back on its wheels. This could become a judgement call. Be sure you are
heard. Make yourself heard.
OFFICIALS CALL Officials reserve the option of amending these parameters (cut off times, number of heats,
qualifiers from each) based on pace, number of total entries and/or other factors. There will be positively
no arguing, fighting or belly aching. The doors have been open to us on a grand scale, and there will be
zero tolerance of poor sportsmanship. Represent the hobby with respect and professionalism.
Officials call is final.
