Before risking my own I wanted to know if anyone had flown the Mini 3 with the downward vision & ultrasonic sensors disabled? Will it still fly in GNSS mode or does it trip it into atti?
I plan to do some flying from boats in the near future, and so the whole landing protection thing is a no go. In GO4 you used to be able to disable it for the phantoms but in fly it seems you can’t.
Yes it is fine covering them. Full sat lock with cardboard taped over sensors.
GPS remains locked, it stays in Normal mode, and does not revert to Atti mode.
I’ve done it while flying the Mini 2 indoors, stops it gaining altitude when flying close over furniture, no issues to report.
Fab, good to known
Be careful when landing, as it does know where the ground is and comes down quick 
I’ll only be using it if I’m on a boat, at which point it’s normally a hand catch (deffo with gloves on).
It doesn’t work with the sensors enabled as by the time you’d get it into landing mode you might have moved too much (either vertically or horizontally), needs to be a snatch and grab basically 
Amateur ;o)
Would this be a good idea if flying in fog to assist with coming back down?
There’s a reason we still use phantoms for nearly all boat work, nice big legs to catch
So, ressurecting this thread with an update.
I had all kinds of strange behaviour taping over the sensors, very jumpy vertical motion as it tripped in and out of thinking the sensors were obstructed vs giving valid input.
Obviously some people here have had good results but I wouldn’t trust it.
The ‘clean’ solution I have found is to set
“g_config.flying_limit.avoid_ground_and_smart_landing_enable”
to zero in drone hacks. This keeps the downward sensors active (so you still get the radar warning), but disables them for landing and collision avoidance, which is exactly what I was looking for.
