I got caught once with my micro car when I was lining up on the grid. I am used to my quantum speed control in my 1/10th scale and always hold the brake down before the start for that extra punch off the line that is a common feature of those speedos. Anyway, I forgot to disable reverse on my micro car which has a quantum micro in it and when I lined it up on the grid I held full brake like always but the car backed right into the guy behind me. I was pretty embarrased. I didn't get in trouble and they let me race it anyway.
