2017 Remote Control Demolition Derby

IF IT DOESN’T SAY YOU CAN, DON’T DO IT UNTIL YOU ASK
Sportsmanship is paramount.

1.0 CHASSIS:
Minimum 23 inches long (Slash), 21 inches long (Rustler), maximum 26-inches long
12-inches wide, max
Height minimum of 5.25 inches at fender (+/- .25 inches), and minimum 7 inches at roof. Measured from the ground
Weight: ~7 pounds with battery.
Traxxas Slash or Rustler, or similar Short course trucks.
No all-wheel drive.
Stock plastic parts or RPM/nylon only!
“No aluminum upgrades” besides LCG (low center of gravity) extesion plates on non-Slash (Rustler) chassis
Any tires/wheel combo
Two wheel drive (rear) only (4wd discouraged, if run, remove front drive)
Any shocks.
No homemade suspension parts, chassis or driveline parts.
No weight added to frame
No rear chassis bumper.
Aluminum steering parts are not allowed beyond stock equipment.

2.0 BODIES:
Aluminum Bodies only (using For Sale-type signage, soffit, coil stock) .024 gauge (like For-Sale Sign)
Legal Bodies include: Roark, Feerhle, Tillery, Witt, JMW Spec, etc.
No AR aluminum. No PVC coated aluminum. No sheet aluminum. Aluminum should EASILY Bend with fingers.
No welding. No solid-form cars (melting metal, casting a body, press/stamping body form).
No reinforcing of the body or the frame. Four point cages allowed. Positively no crawler cages.
No weight added to body
Major build point: no bodies wrapping tight around or under bumpers. No bracing / kickers.
No extreme body-lining. Body lines to replicate that of a real car are fine, side lines are fine to harden. But no stiffening lines the length of the hood, roof or trunk.
Small bead rolls to reflect GM Wagon roof lines are permissable, but cannot be enhanced in any way
Roof Signs should not be extreme, and should not act as protectors to prevent roll-overs or aid/assist in putting a car back on its wheels.
No full-wedge vehicles.
Window openings should be cut out, like a car would have the glass removed.
One rear, single-layer strap over the back window, two allowed over the front window.
Two single layer straps from bumper to hood is allowed.
KEY POINT: These cars should bend.

2.1 FASTENERS:
Fasteners should not be used to excess; be prepared to remove or drill out items.
General guides: three or four over the fenders and quarters. five a side to hold cage in doors, three to five to hold each bumper on.
Thin beading wire – not mechanic or actual nine-wire – is allowed with no more than three loops passing through any opening.

2.2 BUMPERS:
Homemade front / rear bumpers outside the body/mounted to the body are acceptable.
No rear bumpers on the chassis of the slash, front bumper should be either factory slash or RPM.
No nitro/foam bumpers.

2.3 CAGES:
Maximum thicknesses three-layers of metal/tripled for cage, ad 3/4-inches wide.
Braced cars/kicker’ed cars will not run.
Rear window bar and bumpers are subject to the same parameters. Window bar and cages are only instances where tinwork may exceed three layers, but should not in any case exceed four layers.
Door bars should not extend forward into hood and fenders beyond the body mount points, nor extend backward into the quarter panel/trunk area past the body posts.
Diagonal struts between the door bar and body mount bars (front and rear) are not encouraged at national events.

2.3.1 WIRE ON CAGES
To help lower body heights, you may use wire to wrap through the hood or trunk and around body mount (dash, trunk) BAR, and it must be OUTSIDE the area of the body mount itself. It cannot wrap through/around or attach in any way to the chassis.

2.4 ATTACHING BODIES:
Body will be held on in four OEM locations only, and by pinned OEM or screw-on mounts.
May mount through body or through cage bars.
A fifth attachement point is allowed in the form of a skidplate (2.5 x 3 inches), and may be secured to the front of the chassis by a single (1) self-tapping screw. The plate should attach to the aluminum body with 2 rivets or screws and should attach to a single-layered core support. It should not loop through the existing traxxas-style on-board bumper.
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).

2.5 PATCHING:
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 bent to match body lines.

2.6 DECKING:
No full decking/shoeboxing. Cockpit area should be open on all cars. Come prepared to cut these areas out. When you look through a car window, you see to the floor area – when you look through the windows of the RC car, you should see the plastic chassis.
On Wagons: A single-layer deck with no fold-overs may run from the back bumper and arc up to the rear body mount or cage bar. It can be attached in only two spots: the back bumper/tailgate and the cross bar. It is expected there will be three to five fasteners at each point. The deck cannot connect to the quarter panels, and may not be included in any patching process. Sedans have a trunk lid and cannot do this
On Trucks: No decking of the bed.

3.0 ELECTRONICS (Batteries, Motors):
Any single 2s battery with a maximum of 6000 MAH (stock style rules) 7800 MAH (National). Battery must fit in OEM tray (6.25 in long, 1 in tall, 1.75 in wide). No double battery setups.
Any motors, brushed or brushless.

4.0 TRACK:
Track is adjustable to size, from as small as 8 x 8 feet, up to 20 feet by 20 feet. Elements such as setting, space, cars will affect track size.
There will be a three-foot gap around the track for spectator safety. Tracks should have a six-inch tall wall to limit ejecting of cars.

5.0 PROCEEDURES:
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

5.1 DURATIONS:
Heats will have a rescue cutoff of 15 minutes, features of 25 minutes.
Once an event on track has elapsed a certain time frame – heats ~15 minutes, the feature ~25 – 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.

5.0.1: BLIZZRD BASH DURATIONS
In head-to-head rounds (Round 1, winner’s round 2): You will have a 10 minute time frame, other non-feature rounds will be 15, the B feature and national championship will be 25.

6.0 RESCUES:
Cars will be released from a stuck position only twice per on-track appearance by officials. 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 rescue.

6.0.1: BLIZZRD BASH RESCUES
Blizzard Bash will be a two-rescue event in all rounds.

6.1 SELF-ESCAPES:
If freed on their own or with help from another driver, it does not count. The third time, you will have on 30-seconds to free yourself or be freed by another. Once the clock expries, you are out.

6.2 SHOT CLOCK:
If you wave the official off, the clock will begin and you have 30 seconds to be freed. Once a driver calls for a resuce, their shot clock will stop.

6.2.1: BLIZZRD BASH SHOT CLOCK
In head-to-head rounds (Round 1, winner’s round 2): You will have a 20 second shot clock. All other rounds will have a 30-second clock.

6.3 ROLLOVERS:
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 wal.
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.

6.4 EJECTIONS/NON-RESCUE ELIMINATIONS:
There are only a few instances where a car is automatically out. The first is the body connection clause outlined above in section 2.4. 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 in the arena 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.

6.5 RESCUE PROVISION:
If you become hung on a car who was already on the clock, and that driver calls for an assist, and you are freed as a result, it will not count against your alloted two. If you roll someone, and you are both stuck, only the car being rolled will be counted as using a rescue.

7.0 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.
