Night Race | Mantis 5"

This is a tipical fpv meeting here in rome in our summer nights, friends, drone racing and a lot of fun!
The crashes are random and I saw from my gopro footage that I have a ratio of lipo/crash of 1:1 LOL I need to improve or I'll finish to kill of my lipo and props! (btw these aren't all the crashes, there are many others)
