Intermediate Class Rules
It's become very apparent over the last 4 years it's almost impossible to know who has sponsorship and who doesn't in Intermediate so now things will be different this year. One of the common excuses is I didn't know I couldn't. So this year if you sign up for Intermediate you will be required to sign a statement that you have no motor or chassis sponsor of any percentage and if during the year it is discovered you do have one of any percentage you will immediately be bumped to Open and lose all points. Also in a racers 1st event qualifying times will be monitored as with Open/Pro and if your qualifying times would place you in the middle of the B main or higher in Open you will be bumped to that class. As a 3rd way to regulate this class track owners will be asked to consult on their local racers as to who should be in Intermediate. The Intermediate class is designed to be an introduction class for large events and a place for the newer racers or older drivers to race and be competitive. For 2009 it will maintain a national championship. If we continue to have problems with sponsored drivers trying to run in this class it could very well become a division only class in the future. Hopefully the new regulations will solve this problem.
You cannot run in Intermediate if any of the following applies.
#1. You have a motor or chassis sponsorship from a manufacturer or distributor. It does not matter what percentage the sponsorship is.
#2. If you race in Open in one class you must race in Open in all classes.
At the end of 2008 the following will be required to bump to Expert. Any Intermediate driver that finishes in the top 3 in any Division will be required to move up to the Expert class the following year. Any driver finishing 4th or 5th in two years not consecutively will be required to move up to Expert. Furthermore anyone finishing in the top 5 nationally in an Intermediate class will be required to bump up to expert in all classes.
Open Class.
Open class is allowed any level of sponsorship on any parts. This class is now a stepping stone to the Pro class (see next section). We are aware that some racers have signed up for the Expert class at times that have proved they should have been in the Intermediate class instead. We have never had a true drop back rule it was based on our judgment and past performances. In 2008 we will use a percentage rule for this if anyone feels they have signed up in the wrong class before this year. If a racer has raced in at least 2 races in a season and finished outside of the top 60% that racer may drop back to Intermediate. If that racer has raced in multiple seasons in RC Pro he/she has to have been outside the top 60% in each season. Only the seasons where 2 or more races were attended will this be available. (you can't drop back if you were outside the top 60% and only ran 1 event). All of this is providing you don't have a chassis or motor sponsor of any percentage.
Pro Class.
For 2009 the the previous Pro list from 2008 will be our Pro class drivers. The top 3 in each division in expert at the end of 2008 plus the top 5 Nationally in Expert will also bump to the Pro class (after the International Finals). Also the following applies for Pro class qualifications. Past RC Pro Expert National Championship, Division Championship or ROAR National Championship or placed in the A Main at a ROAR Nats or IFMAR Worlds will automatically be in the Pro class. As with anything loop holes are pointed out so because of that possibility we will also allow a racer who feels they SHOULD be in the Pro class to submit a resume for review. These will be reviewed and based on past performances in RC Pro and other large events these racers may be allowed to enter the Pro classes. These resumes for review should be sent to nitrooffroad@rcprosites.com
WHY a Pro Class?
This is designed to equalize the competition as much as possible in the Expert/Open class by moving the racers who have dominated that class into the Pro class. These racers are in fact PRO drivers. By equalizing the Expert class it should in turn make room for the Intermediate drivers who SHOULD be in expert to move up and truly make Intermediate for the racers described in that class definition. You do not qualify for the Pro class by your sponsorship level you qualify by your performance as described in that section.
Driver Eligibility. Division rules.
The RC Pro Offroad classes are open to all racers based on the descriptions in the previous sections..
Each racer can race in any division and score points in that division. This allows for each racer to compete for multiple division championships if they wish. Points from another division will not count toward any division except the one the points were scored in.
A Division standings will be based on the best 2 races for each racer in that division.
The National standings may vary. The National standings will be based on each racers best 2 races of all of the races that points were scored in. If the National standing is higher than that racers division standing then that standing will be used for that racers equalization formula. See the explanation of that next.
Points
One of the problems we have had in the past has been a disparity in competition level from division to division which has shown in the points brought to the finals in the past. In an effort to remedy that we will do the following.
The division points championship will be determined by the points scored in that division (same as in the past).
Each racer will have a points equalization based on their standing in their division. Please see the following examples.
Examples. (see the points format page for a full points equalization)
#1. The winner in each division will be assigned 470 points, all division 2nd's will receive 466 points. This will continue with a 4 point split between positions down to 12th position. From 13th to 23rd is 3 points between positions, 24th to 34th is a 2 point separation and 35th down is a 1 point separation. This formula will be used for all racers who have ran at least 2 events in their division. Anyone who has only raced in one race will go into the finals with the points that were scored in that one race.
#2. Racer A did not race in 2 races in the same division. Racers who's best 2 races are in different divisions points total will be ranked against all other racers BEFORE the equalization. Based on that ranking be it 1st or lower Nationally that racer will be equalized with the appropriate points score the same as if it was a division standing.
Why not just dump the points for the Finals?
RC Pro always has been and always will be about rewarding consistency through out the year. The National Championship should be based on who was the most consistent. This formula will still reward racers for their division performances plus gives more opportunity to RACE into the National Championship. In the recent past some division positions have come into the finals 30-40 points behind the same position from other divisions. Each division position will come to the finals on equal footing with the same positions from other divisions now. Also by closing up the points between positions it will give more racers a chance to RACE into a championship. The points for the Finals is still 1.5 times the normal points score.
