If you're battling city traffic, don't just look at speed—look for a drone with "smarter eyes" (advanced sensors) that won't get spooked by power lines or tight alleys.
For those running long-distance routes over quiet terrain, the conversation shifts entirely to flight endurance and how the drone handles crosswinds when it's flying empty versus fully loaded.
You also need to be realistic about your cargo. A drone built for light mail will struggle with the weight shift of a liquid-filled medical kit, so check the mounting hardware first.
Lastly, think about the "brain" behind the bird—make sure the control interface feels intuitive for your team to use every day, not just something that looks good in a demo video. Choose the tool that keeps your packages moving and your maintenance costs down.
