My P4 went berserk while returning home automatically and slammed a tree trunk. Lost 3 props, one prop attachment, cracked camera glass and cracked both fore arms. Now I'm mainly seeking advice on how to fix the cracks on the arms. Likely the fracture only wraps the bottom half of one of the arms and the other is more of a minor injury I am not that worried. Please refer to images. I'd love some feedback/advice! This is my first post too
