I need some help choosing a Tekin speedo. I only race sedan (rubber tire 13.5,17.5) on asphalt and very soon carpet. I was wondering if the "RS" was better/faster for "strictly" stock rubber sedan racing compared to the "RS-Pro"?
Have any of you guys actually tried to do an A/B type of test with the two different speedo's using the same car/motor/battery combo to see which is faster for Stock racing?
