Last night on my backyard deck we started getting swooped at by local bats. I quickly launched my Spark to see what would happen, initially fearing they may hit it and knock it down. Surprisingly they quite noticeably avoided it and stayed away when I flew near my deck. Started chasing them as I would have liked to video them but it was too dark and I couldn't get close to them anyway. Anyone else have experience with bats and drones.
