DJ, with a little throttle control 20 minutes is not out of the question. I've had a couple of flights that the air time was closer to 25 minutes. The other end of the equation is that with a full charge the plane is wicked fast, so flying fast can induce you to forget about throttle maintenance. It will also take about 35 minutes to charge. The placement of the charge port also changes the cg a little. I'm rebuilding a jet model and that looks like the hardes one to hang a charge port on.
