5 min qual - 5 min mains - usually - unless there is a big race weekend - then the mains for nitro are usually 15 min - however i have seen 1/8 scale mains that were 1/2 hour long. Usually when you sign up for 1 race - you race 2 heats and the main - with a few mins in between the heats for practice and tuning. If you enter one class then you race 2 qual heats and the main - if you enter more than one class - then they usually drop the cost for the next class - and so on....
