I tried putting my M2Z through a spot I fly my 5" FPV drones through regularly - I fly up the hill, under the trees, then up between the roof and the trees and out over the house. Had my sensors on - as I was curious. But they actually trapped me - I saw my opening, between roof and treetops - it was narrow - but enough - so I made for it, and was close - when - darn - I couldn't go forward through the opening ... the sensors not only were warning me (I was use to that) but they wouldn't let me proceed - weird feeling to push on the stick and nothing happens - so I had to find another, unplanned, path out, or retrace the path I'd taken in - didn't work- I caught something - and went down - no damage luckly - so overgrown in there. But next time - I'll do it sport mode. The sensors are a liability if you want to get in close to something. Useful sensors would only kick in inches from what you were hovering near. And just not let your props make contact - but give you all that space to fly in. The current sensors are not made for close proximity work. Oh well. On to sport mode.
