We have recently commissioned two USA designed "Tuffwing UAV Mapper's".
These are big and tough. With more adaptable payload options, handle stronger winds and cover more ground just to name a few features. Oh and they have a parachute for those tricky landing sites and for public piece of mind.
The stability in the air when the wind is blowing still blows me away. That translates to good Nidar imagery and good data.
