Here's something that most people don't know.
The United States is not the only place in the world where people exist.
Can you imagine how crazy it is for someone outside the US to want to buy a drone.
The mind is boggled!!
Customs can, should they feel like it, ask you to show proof of purchase of items valued over $800, manufactured abroad, but purchased in the US. If you cannot, they can charge you import duties. You can appeal, but your children may be alive to...
Something has been shorted. Think of seawater as a liquid conductor. Immersion connects every soldered electrical connection in contact with every other electrical conductor. I’d never fly that drone again.
