In the field finally with the XP-1 3D printed quadcopter. Doing some high speed runs, and aggressive flying I got just over 10 minutes of flight time before the lights blink. You do have another minute after the lights blink but that’s about it before the ESC’s go into low voltage protect and shut down.
First is me being careful.
Around 6 minutes is some flips, high speed tests, and other stuff.
