Hi Guys

So I got the H520 last week and i have tried to test the obstetrical avoidance by bring it close to me but it does not seem to react to me being there at all. I have ensured its armed and showing on the St16 as on but nothing . What am i doing wrong ?

Thanks
Ryan
 
One thing that comes to mind is the landing gear. Try it with the landing gear in the UP position, if you haven't already. Also, some objects may reflect the ultrasound signal in a weird way. When I want to test the ultrasonic sensors in flight i hold up my ST16 controller, flat surface towards the drone.

Also, when you enable OBS, can you hear clicking from the sensors? Does the OBS system display the distance towards the obstacle and does it reflect reality more or less?

You will only hear it on the ground, when you place your head in front of the sensors.

Hi

Yeah i hear it and it now shows up saying the distance , I see with the H version of the drone it it moves back but with this one it just shows you is there a way to make it move back ?

Thanks
