The recorded flight data would reveal what actually happened.
I know that people suggest using rice.
It's very inefficient, but the myth...
That won't have been the reason the drone crashed.
His recorded flight data might show what actually caused the incident.
Using rice is much less effective that rinsing with alcohol and letting the drone air dry.
