What is the best way to confirm an sUAS with a new payload is within its weight limits?

• A.Estimate by hand and compare with a previous flight
• B.Rely on the payload's advertised weight alone
• C.Weigh the complete aircraft in its flight configuration before takeoff

Why

Only the complete flight configuration gives the true takeoff weight, including mounts, cables, and battery. Weighing the assembled aircraft removes guesswork about limits and performance.
