The rules have been updated to show the new rear wheel/tire spec – Scaleauto SC-2424P.
The hard BRM foam tires put down a layer of harder rubber on the track that is difficult for the softer Scaleauto tires to hook up on. We will be cleaning the track to pull up the hard rubber and put down the softer Scaleauto foam rubber.
I have tried shore 30, shore 22 and shore 15 BRM rubber tires and none of them worked well.
Motors – I personally would not a red motor but I have not actually run one recently. We did run them in some of our previous BRM series. Maybe it could work. I’m not going to try it but its left in the rules in case someone would like to give it a try.
Rear tire specs have been updated. The minimum rear tire diameter at the start of a race is 26.5mm.
Tire Question – This is not some Euro carry over rule. This rule exists in many of the series run in the States. Our truer is not set up for putting a conical shape to the tires but it can easily be done. The purpose is to have a smaller contact patch for front tires so their is less drag when running the large width wheels/tires.
