Max Vne for a given frame?

Most of my frames are large, with large props and low kv motors.  Is there a way to calculate the Vne to determine when the lagging props with stall?  Something where you would input prop diameter and rpm range I would think...  Using GPS to determine speed combined with high winds could definitely cause problems in an auto mission.

  • We've mapped in winds around 8m/s, of course it's hard to tell what it really is a 100m up.  But there was definitely something odd going on.  A lot of bucking and the unit slowing down from 9m/s to 3 lol!  Should probably be ok as I wouldn't want to fly with wind speeds any higher.  Would be good to know for operational manuals to satisfy government regulations.
