As I wait for some extra batteries to arrive (not enough flight time to make a trip somewhere worthwhile), I continue practicing flying the quad in my backyard. This time, I take it up early on a hot, hazy morning... for what turns out to be a number of spins around the horizon. Alas, the tall trees on my property make it tricky to go anywhere and maintain line-of-sight, and at the height this morning, it's so small it's easy to forget its orientation. FPV needed, for sure!
