Am I the only person that has all the sensors turned off all the time?
Managed quite OK without flying into anything with the P2 that didn’t have them.
OK - yes - I would use them if I was going to attempt a (lunatic) Litchi mission like some people … eh @colinbm 
(I still love that video of it … miles away … but still navigating the tree foliage with alactrity! )
