TRACK RULES
Safety is our first priority! If you see something that is unsafe, please report it to the Race Director immediately.
1: Have Fun! We all have our own definition of what is fun. Please use common sense.
2. Do not walk on the track unless you are marshalling, fixing the track, taking pictures or retrieving a car. When you do walk on the track, wipe your feet first.
3: All cars must be no lower than a minimum 4mm ride height. This is to protect the track carpet.
4. TIRE DOPE
Legal: SXT Regular, JDub’s
Illegal: SXT Max (Red cap), any tire dope not specified in the Legal category
USING ILLEGAL TIRE DOPE WILL RESULT IN IMMEDIATE DISQUALIFICATION
5: Your car must be on the “Tech table” the race before your race. This assures everyone is prepared for their race and helps the event stay on schedule.
6: All cars must be “Put down” in Turn 1 and “Taken Out” in Turn 4 ONLY to avoid unnecessary collisions and broken cars.
7: You can ONLY drive from the driver’s stand. Driving from anywhere else is immediate disqualification from your race.
8: If you stop on the track to make adjustments, pull into the infield to avoid unnecessary collisions and broken cars.
9: YOU ARE REQUIRED TO MARSHAL AFTER YOU RACE. After your race, put your car on the “Impound table” and go back out to marshal. If you cannot marshal due to physical/health issues it is your responsibility to find someone to take your place marshalling. You can be docked a lap for chronically not marshalling.
Do not leave your marshalling station until the race is over
Do not work on cars while marshalling
Do not play on your phone when you are supposed to be marshalling
Do not sit in a chair while marshalling
No children under the age of 8 are allowed to turn marshal.
Please wear shoes that allow you to run. No flip flops, sandals, or open toed shoes are allowed when turn marshaling.
10: No short tracking – 1 lap penalty.
11: Do not drive against the flow of traffic or use reverse at any time during the race day.
12: Do not continue to drive a broken car. This can cut the carpet. Your car will be black flagged.
13: Race Directors are in charge and have a final say in any decision made.
14: Be courteous to other drivers and their vehicles. Do not crash other people on purpose. You can be disqualified for intentionally wrecking other drivers.
15: Do not yell or make comments to the marshals before, during or after a race.
16: Do not come off of the drivers stand during a race for any reason. It distracts the other drivers and can block their vision. NO EXCEPTIONS!17: Lapped traffic needs to try to move over for the leaders. There is no reason a driver 2 or 3 laps down should be interfering and taking out or slowing down the leaders.
18: Any driver found guilty of placing fellow racers, turn marshals, mechanics, or spectators in harm’s way will be asked to leave immediately and you will also forfeit any fees paid.
19: If you are not racing or practicing, please do not enter the driver’s stand.
20: Battery rule: 4.22 max volts (1 cell) / 8.44 (2 cell) max volts.
21: No 1/8 scale RC’s are allowed.
22: Zero Tolerance Policy – No yelling, fighting, threatening, whining, arguing, trash talking, or sabotaging other drivers.
23: All participants must pay for practice and racing prior to placing your vehicles on the track.
24: No foul language. Children do not like to hear it! (And most of their parents!) Please keep it PG.
25: Smoking is only allowed in your car. Take your cigarette butts with you. I should not have to clean them up. If this becomes a problem you will be asked to not come back. Entire property is monitored and I will know who the leaving them behind.
26: No Food or Drinks are allowed on the Track or Driver Stand.
27: Please help keep our facility clean by picking up after yourself. We have trash cans throughout our facility. Please use them!
28: All Batteries must be taken with you when you leave the track. Do not leave your batteries at the track!

SPORTSMAN RTT (21.5)
This class features a NAS-Truck style body, CRC Rubber Tires, any
1/10th pan car chassis, MOTIV TOUR 21.5 motor (Part #GRC2010), and Electronic Speed Controls (ESC) approved under the “ROAR Sportsman Class ESC rule” set to the Sportsman profile at all times. ROAR approved 1-cell battery. NO SPOOLS, diffs only. Driver eligibility for this class is limited to “Sportsman” level racers as defined by TOUR/Event Promoter.
General Rules
Batteries
Only 1-cell LiPo batteries (nominal voltage; 3.7V or 3.8V) having received ROAR approval are to be used. Label must be clearly visible.
Single Power Source
In all TOUR classes the 1-cell LiPo main battery is the only power source permitted for any electronics in the car (i.e. receiver packs are no longer permitted). The only exception to this is the Open Modified, Pro RTC, and 12th Modified classes, where receiver packs are permitted.
Voltage Limits
1s LiPo batteries may be charged to a maximum of 4.22v per cell, regardless of their nominal rating. Batteries presented to Tech over the 4.22v max voltage per cell must be drawn down to 4.20v per cell before they will be permitted to race. This should prevent the problem with voltage creep back up over the legal limit.
Voltage verification to be done as part of standard pre-tech race procedure
• 4.22V per cell is not only the maximum voltage per cell that LiPo batteries may be charged to......it is the maximum voltage per cell allowed to be presented to the motor drive circuitry for the purpose of powering your car.............period.
• Any attempt to use a secondary source of power (receiver pack battery or booster) to drive the motor at a higher voltage than 4.22V per cell is prohibited. No sneak circuits, no gray areas. This is blatant cheating.
• If any violation of this rule is suspected, the race director has the right to perform an “in-line test” of the car’s operating voltage on the
starting grid.
· Voltage manipulation of any sort is a serious issue affecting our mutual safety. In an attempt to verify any tampering, the following measures will be taken:
o Random voltage measures on the racing “grid”
o Random post-race voltage measurements to detect irregular high “end-point” voltage after a run
o If either of these tests point to an irregularity, the race director reserves the right to impound the car for further inspection. (i.e. disassembly of the battery and/or motor) o It is further recommended that the results of these measurements/inspections be made public to ensure the comfort and credibility of all involved.
• All battery mfg. labels must be clearly visible. Any battery presented without label will not be allowed.
21.5 Motor rules
Motor for this class will be the MOTIV TOUR 21.5 motor (Part #GRC2010). No modifications can be made to this motor at all. Any signs of tampering will be result in disqualification and the motor will be confiscated. Minimum Stator Resistance for this motor is a 29.7 milliohm single pole resistance “average” of the A, B, and C poles when measured 75 degrees Fahrenheit. This is a “hard” measurement, not subject to the 99% testing rule. A Instek
GOM 80 milliohm meter will be used to tech Motors.
Heating & Cooling (Batteries and Motors)
Batteries max temp will be 90 degrees; motors must be no less than 5 degrees below the ambient temperature of the track area when the vehicle is presented for tech inspection. Racers will not be able to race if battery temp is too high or motor temp is too low. Fans will be allowed (ambient air), No forced cooling of batteries allowed (freeze spray, etc.) or any other product used to cool the battery.
Lipo sacks will be required at all TIMES!
Tires
• RTC & RTT Classes to use CRC Rubber Tires with stock inserts:
• Team CRC GTR rims will be the only rims allowed (Part #2310). The only front tires that will be allowed are Team CRC RT-1 (Part#2311) or Team CRC Mounted RT-1 (Part#2314). The only rear tires that will be allowed are Team CRC RT-1 (Part#2312) or Team CRC Mounted RT-1 (Part#2316). Tires must be mounted “F1/NASCAR” style with the larger sidewall visible from the outside profile of the car. Sidewalls may be glued. Tires must display the molded letters (CRC). Stock inserts only, with the front inserts in the front tires, and the rear inserts (the grey ones) in the rear tires. No Modifying inserts or “double stuffing” of inserts will be allowed. You are not allowed to add anything to the inside of the tire, no duct tape, no glue (to the inside), or anything else that did not come from the factory. You are not allowed to modify the air holes of the rim. This means that you cannot plug them, make them smaller, or make them bigger. The intent here, is to run these tires as provided by CRC with no tweaks or modifications AT ALL. PERIOD.
• “Smooth” Rule: In an effort to keep rubber tire racing easy, convenient, more affordable and fun, we are instituting a “Smooth Tire Rule” for rubber tires. The goal here is to eliminate the need for tire prep work that includes truing, sanding, paddling, grinding or ruffling the tires. We hope to return rubber tire racing to its intent, which was more of a “plug and play” approach.
Tires must show no other signs of wear, other than “normal use”. (After 5 seasons of racing these tires, we have gathered plenty of data on the long term use and wear “pattern” of a tire that have experienced “normal use”.)
The normal pattern of wear on a CRC tire is a slow-forming “wear ring”. This ring is parallel to the direction of travel or rotation and slowly gets deeper as the tire wears. This ring appears after many runs. Other than that wear ring, the CRC tires do not show any signs of surface deformation under normal use, and there are NO perpendicular lines or waves of surface imperfection. Under normal use, the tire surface stays flat and the race surface of the tire stays smooth race after race and will not show any ridges, ruffles, graininess or any “waves” of wear. Thus, if a tire shows signs of anything but a smooth surface, it has experienced some other outside factor other than racing the tire on a carpet surface.
• Therefore, all rubber tires presented at tech must comply to these guidelines:
▪ The tire surface must be smooth and free from texturing or waves.
▪ The tire cannot be trued, ground, filed, touched or manipulated * in any way with a tool or object.
▪ No drills, dremel, truing, sanding, paddling or grinding the tires. The only thing that should touch the tire is the carpet you will race on.
▪ The tire surface cannot show ANY sign of waves, ruffles, texture or lines. No past “shadow” texturing, or faint ghosting patterns. Smooth surface ONLY.
▪ No grinding the “bead” or mold line. If you feel the tire needs to be “broken in”, do it on the carpet track. Run it in advance, let the carpet race track do the work.
▪ If you raced in the past on some kind of surface that left anything but a smooth surface, those tires will not be legal for use. Smooth surface only.
Electronic Speed Controls (ESC):
Competitors must use an ESC approved by ROAR for Spec use. The ESC must be set to the Sportsman mode (i.e. no timing boost, cheat modes, etc.) at all times when used in these classes. No wirelessly configurable ESCs are permitted in these Spec classes. No Delayed Turbo.
ESC’s hardware and software version used in a TOUR Championship event must be available to the racing public through normal distribution channels at least 30 days prior to the date of the event.
Any questionable ESC is subject to further analysis and may be removed and held during an event at the race director’s discretion.
ESC’s must be configured so that they cannot be wirelessly updated when presented for technical inspection and as used in all competition (qualifying and mains). Some examples include removal from the car of any separate, external wireless modules; removal of any specific receiver used to enable wireless programming; and / or a locked software mode in the ESC which prevents wireless updating (locked mode must be indicated by a specific distinctive blink code or LED color).
Also no driving enhancement radio or gyros (AVC) may be used.
No modifications to the ESC circuitry are permitted. This includes but is not limited to jump circuits, extra non-factory wiring configurations that include extra components such as buck boost circuits in the motor drive circuit and/or low ESR/super capacitors. Normal Factory supplied components that are available to the general public are allowed in the configuration suggested by the manufacturer of the ESC. No Low ESR or Super Capacitors will be allowed. Any manufacturer that offers a Low ESR or Super Capacitor as part of their standard ESC offering, must offer a low cost electrolytic cap as an option as well. This low cost electrolytic cap must be approved by the TOUR and will be all that is allowed for competition.
Factory supplied capacitors, if wrapped in heat shrink, must be identifiable. Therefore, only clear transparent heat shrink is allowed. The TOUR will maintain a list, with pictures to assist in tech, of the normal factory supplied components for each ESC.
Modified classes may use receiver packs, can modify ESC circuitry as necessary, and can use any capacitors in their configuration.
Weight Minimum
• 39 oz.
Body Rules
• 2" spoiler max (no side dams attached)
• Tailgate/rear bumper must be left in
▪ We will be using a 1.7" measurement from the top of the tailgate to the point where the truck body cut line needs to be, as a standard measurement for all 10th scale trucks, regardless of where the mold line is. This will provide a constant cut for all brands.
• Holes may be drilled in the body for the purpose of mounting the body or transponder. Any other holes in the main body surface area, for any other reason are prohibited.
• Minimum roof height: 4 3/8".
• Approved Bodies for 10th Scale Truck Classes

▪ Mon-Tech Racing Part #MB-022-012
Race Director’s Discretion:
TOUR has done its best to define rules encouraging fair and competitive racing. We have focused on defining simple, clear, and understandable rules.
We realize it is the nature of every racer to push the limits, but the time and energy required to write an “air tight” rules package is not available to us. (And we don’t have the money to pay an attorney to write R/C rules.) Therefore, we ask that each of you adhere to the rules listed and follow the common sense guideline that we have all observed for over 20 years. These are the “generally accepted guidelines” that usually go without saying and simply follow ROAR’s most basic oval guidelines (i.e. wheelbase, width, tire [type, diameter, & width], single speed, one-piece drive axle only, etc.…)
However, in the event that there is a question or discrepancy, the Race Director has the FULL AND EXCLUSIVE AUTHORITY to interpret the rules. His or Her decision is final for the purposes of that event.
The TOUR reserves the right to edit and/or “repair” the rules listed above to account for oversight, unforeseen circumstances and /or in the interest of promoting fair competition.
Tire Traction:
The only Traction compounds that will be allowed are
o SXT 3.0
o J-Dubs Tire Rub

Racers will not be able to race if battery temp is too high or motor temp is too low. Fans will be allowed (ambient air), No forced cooling of batteries allowed (freeze spray, etc.) or any other product used to cool the battery.
Lipo sacks will be required at all TIMES!
Tire rules
World GT Tires are the only tires allowed for use in the TOUR Sportsman Truck and 17.5 Stock. World GT Tires must meet the following specifications:
- Tire and wheel must meet 10th scale specifications
- Tire compound to be Japanese R4 compound, 38 shore - Tires must have an identifier ring of purple or blue colored foam visible around the circumference of the tire
- Tires meeting the above criteria will be considered legal for use after samples are submitted and approved by TOUR.
Current Approved WGT List
• BSR Tires
• CRC
• Contact
• Excelerate
• Jaco Tires ( white rim with purple or blue stripe)
** Tampering with or deviating from the original foam (Japanese R4 compound) in any way could result in disqualification from an event and suspension from any TOUR event for up to one year (including the Snowbirds, Ovalmasters, and TOUR Nationals).
Electronic Speed Controls (ESC):
Competitors must use an ESC approved by ROAR for Spec use. The ESC must be set to the Sportsman mode (i.e. no timing boost, cheat modes, etc.) at all times when used in these classes. No wirelessly configurable ESCs are permitted in these Spec classes. No Delayed Turbo.
ESC’s hardware and software version used in a TOUR Championship event must be available to the racing public through normal distribution channels at least 30 days prior to the date of the event.
Any questionable ESC is subject to further analysis and may be removed and held during an event at the race director’s discretion.
ESC’s must be configured so that they cannot be wirelessly updated when presented for technical inspection and as used in all competition (qualifying and mains). Some examples include removal from the car of any separate, external wireless modules; removal of any specific receiver used to enable wireless programming; and / or a locked software mode in the
ESC which prevents wireless updating (locked mode must be indicated by a specific distinctive blink code or LED color).
Also no driving enhancement radio or gyros (AVC) may be used.
No modifications to the ESC circuitry are permitted. This includes but is not limited to jump circuits, extra non-factory wiring configurations that include extra components such as buck boost circuits in the motor drive circuit and/or low ESR/super capacitors. Normal Factory supplied components that are available to the general public are allowed in the configuration suggested by the manufacturer of the ESC. No Low ESR or Super Capacitors will be allowed. Any manufacturer that offers a Low ESR or Super Capacitor as part of their standard ESC offering, must offer a low cost electrolytic cap as an option as well. This low cost electrolytic cap must be approved by the TOUR and will be all that is allowed for competition.
Factory supplied capacitors, if wrapped in heat shrink, must be identifiable. Therefore, only clear transparent heat shrink is allowed. The TOUR will maintain a list, with pictures to assist in tech, of the normal factory supplied components for each ESC.
Modified classes may use receiver packs, can modify ESC circuitry as necessary, and can use any capacitors in their configuration.
Weight Minimum

Race Director’s Discretion:
TOUR has done its best to define rules encouraging fair and competitive racing. We have focused on defining simple, clear, and understandable rules.
We realize it is the nature of every racer to push the limits, but the time and energy required to write an “air tight” rules package is not available to us. (And we don’t have the money to pay an attorney to write R/C rules.) Therefore, we ask that each of you adhere to the rules listed and follow the common sense guideline that we have all observed for over 20 years. These are the “generally accepted guidelines” that usually go without saying and simply follow ROAR’s most basic oval guidelines (i.e. wheelbase, width, tire [type, diameter, & width], single speed, one-piece drive axle only, etc.…)
However, in the event that there is a question or discrepancy, the Race Director has the FULL AND EXCLUSIVE AUTHORITY to interpret the rules. His or Her decision is final for the purposes of that event.
The TOUR reserves the right to edit and/or “repair” the rules listed above to account for oversight, unforeseen circumstances and /or in the interest of promoting fair competition.
Tire Traction:
The only Traction compounds that will be allowed are
o SXT 3.0
o J-Dubs Tire Rub
