So I'm at the park flying close in headed between two trees10' off the ground, I'm blind in my left eye so depth perception is limited, I thought I cleared the two trees before I launched the bird straight up into the tree branches, man that thing went ballistic spinning and tumbling to the pavement below, sounded like an angry hornet, only damage was 2 busted props, replace props took a test flight and all was well, I feel lucky that the bird decided not to stay 40' up in the tree!
Be careful!
