I like to take about 1/2 hour between flights, given the 6 sets of batteries I have and charging at 10 amps I can fly all day. Packs take about 30 minutes to charge.

When trimming I might fly a few laps, land, change something and go back up with the same pack.

The most important flight of the day is the first one, big contest you get one flight a day or maybe 2, but hours apart.

Make the first one count.
