I also ran the Cirtix Comba at the TCS Regional and my car was flying at 33mph down the straight. Then I figured out my brake wasn't working, I thought it's the ESC but on closer examination, my new used radio did not have the brake caliberated properly (should have recaliberated a used system when I got it). A costly mistake but still made it to B-Main 3rd considering I am running a GT1 car without any brake.
Motor and ESC both runs extremely cool given the sunny weather around 75F.
