The "perimeter path" issue you're seeing on the standard M4T firmware is a known limitation of the retail TimeSync implementation when handling KML imports with complex vertices. It often triggers a safety verification loop during flight planning.
We currently have "Export Edition" units in our Tsuen Wan warehouse that run a refined firmware stack optimized for enterprise photogrammetry. These units bypass the standard retail verification loops for authenticated missions, ensuring maximum path efficiency.
If you are looking for a professional-grade solution that eliminates these technical hurdles, we have stock available for inspection. Pricing is $4,800 USD/unit, FOB HK. We require a $30k deposit to secure units from our current allocation.
