You guys race a lot of different classes in one meeting.

We certainly do, there is usually a Fuel race and a RWYB (that you haven't run today) as well. We start with practice from 10am and racing from 11am, we run four classes then break fo lunch, 10-15minutes then back into racing for the afternoon until the classes are done or people start packing up. 

Heats are 3 minutes. Having a stable RMS really helps with the racing day.
