Very seldom.
Between soft walls, and adjustable power, 95% of my repairs are broken lead wires, from the original factory solder job.
Probably 2/3rds of my birthday parties are full speed.
And almost the same percentage of rentals.
With kids being off of school, I've been busy the last 2 days, during the day, with rentals.
Having full speed racing , with cars staying within a foot or two, of each other, for laps at a time, even gets the adults watching, excited, let alone the 5 or 6 year old kids, doing it.
