Motorama MudBOss and Sprint Classes and Rules

---

Preface:
If the rules do not say you can, then you can't.

If you THINK you can, you should probably ask.

We will follow the stock Salvas Mudboss rule-book employed at each North East MudBoss Series event.

Official's decision is final. 

STOCK MUDBOSS

The intention is to take the Salvas Sportsman Rules for 2015/2017, and adapt them for a fun, entry-level RC division. It should remain an affordable division to compete as box stock as possible. The rules below are simple. Its to be a fun, spec class, allowing for competition on fairly equal grounds for everyone. This class is meant to be about driving ability and adjustability. There shouldn't be secrets or trickery. Cheating is thoroughly frowned upon. It should be fun, and open to all skill levels and driving abilities.

SPECIFIC TOUR RULES: COMPETITORS

Points at all regular events: 100-97-95-94-93-92-91-90 on down; +1 for TQ

Any event with a car found illegal before mains start will be full point paying events.

All races over 150L pitstops are allowed (with exception); over 200L pitstop is mandatory

Race durations can be changed after determinations are made on battery life, and the safety of executing live pitstops.

In-Race Breakdowns: If you take the car off the track, it may come back on in A-Mains only. In main events allowing a pitstop if not yet taking pit stop, then you may make repairs and count it as your stop.

Tech will be both planned and random.

Batteries will be tested before the racing, and before mains, along with spares for extra distance races, and all elements above checked visually before going to the track. Batteries over the tour spec on the tour meter will be burned down during the first round of heats, then sent to the rear for the second round and not allowed to race in A-Mains.

Protest rules: If a competitor wants to protest a car there will be a $20 fee that needs to put up with in 5 minutes after a race and specified what you want Tech'ed.

Tech will only consist of 1 item only (ie:) Motor, Shocks, Battery, Speed Control, ect.

If the car is found legal $10 goes to the legal car and $10 goes to series.

If found Illegal the protester will get the $10 and $10 goes to series.

Cheating: If caught cheating by protest or in tech, you will forfeit all points up to that point, and those events will count as your drops. If caught a second time, you will sit out a race and lose any remaining drops. Third offense: you will no longer be welcome to participate on the tour.

Rough driving: Races, above all, should be fun. They should also be clean, and fair. If a driver is determined to be out of control, rough driving or head hunting, they will be warned openly, and if it continues, they will be pulled from the heat or feature in which the offense was committed, but allowed to continue racing that day. A third offense in one day will result in a loss of points for the day and it cannot be counted as a drop. A second instance of rough driving or a pattern of this habit may result in further action, including being parked for a period of races, or losing drops. 

This is to help expand and meet the requests of local drivers and tracks around the northeast. It is to be a positive and constructive environment, and not to turn into a hub of complaint.

Timing Clause: In the rare case of a timing error: Any racer timed under 4 minutes will have their lap rounded up to the next, anything longer than 4 mins will be recalculated, using 240 seconds divided by the average lap time to get laps; laps will be rounded up to the next nearest lap.

Attendance clause:Drivers who leave before the main will be awarded points based on their order after all drivers competing in mains are awarded points. If a driver is seeded, for example, in the B-main, and the order of the day includes an E-main, all drivers through the last-finishing active driver will be scored, and then the departed driver(s) will be scored based on their qualifying spot, A-B-C-D and so on Mains behind those that actively raced in a preliminary feature. You must have one qualifying effort in the book and have been seeded in one of the mains to score points if you do not race in the mains.
