Here is the basic class structure for the 2009-2010 Brushless Racing League Oval Series. We’ll get a full rules update done soon with all the details but this will give the basics.
First, I wanted to make a couple comments. You’ll notice that most classes allow any ROAR approved motor. After 3 seasons using Novak motors nearly exclusively, this was a difficult decision. We’ve had great, close racing and Novak’s motors have proven to be very reliable and long lasting. They have been a great supporter of oval racing and their new Ballistic motors look like outstanding products.
But, for the first time in some years, our sport has a chance to adopt a unified set of rules across most of the country. This will make it possible to run competitively with the same equipment in many series and at most major carpet oval races. We participated in developing those rules but throughout the process we told the others involved that the BRL reserved the option to add limitations to those rules if we felt it was in the best interests of our racers. In the end, we’ve decided that adopting the rules for the TOUR Championship classes will give BRL racers the chance to use the same equipment they run in our series when they go to other major races and kick butt.
The 2009-2010 BRL Oval Series will award points and crown champions in the following classes:
- Super Stock 13.5 / 1 cell Lipo – This class will follow TOUR rules and use COT bodies (Protoform or McAllister) with any 13.5 brushless motor and single cell Lipo which is ROAR approved on or before October 1st, 2009. Motors or batteries approved after that date will not be legal during the 2009-2010 season.
- Pro Stock 21.5 / 2 cell Lipo – This class will follow the same BRL motor, battery and body rules as last season; Novak 21.5 SS Pro motors, SMC 3228 batteries and Nationwide Series style NASCAR bodies running 1 “ spoilers only, no wings. The rear of the body must remain in place above the manufacturer’s molded in cut line.
- Pro Stock 10.5 / 1 cell Lipo – This class will follow TOUR rules and use NASCAR Nationwide Series bodies with any 10.5 brushless motor and single cell Lipo battery which is ROAR approved on or before October 1st, 2009. Motors or batteries approved after that date will not be legal during the 2009-2010 season. Wings and cutting out the rear of the body will be permitted.
- Pro Mod / 1 cell Lipo – This class will follow TOUR rules and use NASCAR Nationwide Series bodies with a TOUR Spec Mod brushless motor (expected to be 7.5) and single cell batteries which are ROAR approved on or before October 1st, 2009. Batteries approved after that date will not be legal during 2009-2010. Wings and cutting out the rear of the body will be permitted. The TOUR Spec Mod motors will be made by a single manufacturer but will be available only through the TOUR (details on distribution to follow).
In addition to these championship classes, we encourage local tracks to run the 17.5 / 1S class with NASCAR truck bodies to give new entrants to the sport a class in which to run. When we run at tracks with local participation in this class, this Sportsman Class will be added to the BRL program.
The TOUR has adopted the BRL approach to heating and cooling of batteries or motors. So we will continue to check battery temp and motor temp in tech. Motors and batteries must be within 5 degrees of ambient at tech inspection. Artificial heating or cooling of motors or batteries is not permitted.
There is a lot of concern that some ESC’s have the capability to feed through power from receiver packs to the motor control circuit. Although our testing to this point indicates that this does not provide a performance advantage, we want our racers to be confident that no one is gaining an advantage through this technique. For this reason, we will place a limit on receiver pack size (TBD but probably 400 mAhr’s or less) and require that receiver packs be connected only to the receiver using standard JST or servo plugs and wiring not to exceed 20ga.
Further, our final rules will state that the voltage as measured at the connector between the ESC and main battery can not exceed the allowable maximum (4.22 v for 1 cell and 8.44 v for 2 cell) at any time. If wired as required, any voltage fed back from the receiver pack through the ESC will be measurable at this inspection point. Voltage is subject to inspection at pre-race tech or at any other time the car is race ready (including on the starting line).
