Yeh sounds like radar beeping,,turn it off see if same,OA only good for low flights so Yeh turn offMy P4P + v2 works great. But, upon starting the props, the controller continually beeps until I lift off. Is it sensing that it is too close to the ground? I haven't even begun flying yet! How do I make this go away? Thanks for any help.
I had the same problem on one of my P4A's. I simply turned off VPS (obstacle sensors), as I don't need them. Perhaps a VPS calibration would help?
