I've read a lot of posts about flight time, distance runs, etc. It seems (I could be wrong) that at least the long distance flyers go out and back at max possible speed. But what of us who just want to go out a couple thousand feet, maximize the time we can stay there, and head back? At some point doesn't it make sense to go slower (using less battery, I would think) rather than faster? These batteries have to work harder going faster, fighting wind, etc. right? What's a good compromise speed to maximize time aloft? (I understand that winds will have an effect here as well). My apologies if this seems like a silly question.
