What is a good starting point for rollout for 1/12th on black carpet? I know it depends on motor and track size/layout, motor temp, etc., but looking for advice on a range to play within. I currently have a R1 17.5 and our track is 88 feet long by 44' feet wide - so the lanes are usually pretty wide for 1/12th scale - 8 or 9 feet in most areas. We are currently only lifting fully off the throttle at the end of the straight/sweeper, plus one other spot in the infield and rolling out slightly through much of the infield. What's a good place to start?
